Bird's eye extinction, or the "bird's-eye view" extinction, is not a widely recognized term in ecology or evolutionary biology. However, it may refer to certain ecological concepts where the extinction of species is viewed from a broader perspective, emphasizing how human activity and environmental changes affect entire ecosystems rather than just individual species.

In the context of optical fiber, a **buffer** refers to a protective layer or coating that surrounds the optical fiber strands. The primary purpose of the buffer is to provide mechanical protection to the delicate glass fibers, which are sensitive to bending and breaking. Buffers help to absorb shocks, prevent damage from environmental factors like moisture, and reduce the effects of external stressors on the optical fiber.

CAVEman is a term that typically refers to a type of immersive virtual reality (VR) environment designed for scientific visualization and interactive simulations. The term is derived from the "CAVE" (Cave Automatic Virtual Environment) systems, which are immersive display systems that project computer-generated images onto the walls, floor, and sometimes ceiling of a room-sized space.

The term "CLD chromophore" typically refers to a type of chromophore that exhibits characteristic light-absorbing properties and is often associated with certain chemical compounds. In this context, "CLD" could refer to specific structural features or categories of chromophores, but it's not a widely recognized acronym in the scientific literature. Chromophores are molecules or parts of molecules that absorb light in the visible or ultraviolet range, which often imparts color to the substances containing them.

Caesium cadmium chloride is a chemical compound composed of cesium (Cs), cadmium (Cd), and chlorine (Cl) atoms. It is often represented by the formula Cs2CdCl4, which indicates that two cesium ions and one cadmium ion are combined with four chloride ions. This compound belongs to a class of materials known as halides and can exhibit interesting properties that are useful in various applications, such as in the fields of photonics and materials science.

Calligraphic projection, often referred to as "cavalier projection," is a graphical technique used in technical drawing and computer graphics to represent three-dimensional objects in two dimensions. This type of projection maintains the scale of one axis, typically the depth axis, while the other two axes (usually horizontal and vertical) are represented at an angle, typically 45 degrees to the plane of projection.

A campimeter is a device used in ophthalmology to measure the visual field of the eye. It is designed to assess peripheral vision and can help detect visual field defects caused by various conditions like glaucoma, retinal diseases, and neurological disorders. The test typically involves an individual looking straight ahead while a series of lights or stimuli are presented in different areas of their peripheral vision. The responses to these stimuli are recorded to create a visual field map, which helps in diagnosing and monitoring eye conditions.

The Carey mask, also known as the Carey mask or Carey-Edwards mask, is a type of orthopedic facial mask used primarily in the field of orthodontics and maxillofacial prosthetics. This device is designed to support the treatment of patients with various craniofacial abnormalities and skeletal discrepancies, particularly those involving the maxilla (upper jaw).

A catadioptric sensor refers to a type of imaging sensor that uses a combination of lenses (dioptric) and mirrors (catoptric) to capture images. The term "catadioptric" itself typically describes optical systems that use both refraction (bending of light through lenses) and reflection (bouncing of light off mirrors) to form images.

The Celor lens is a type of optical lens that is often associated with camera systems and photography, particularly in the context of film photography. It is known for its ability to produce images with certain optical characteristics, such as sharpness and contrast. The term "Celor" can also refer to specific models of lenses used in vintage cameras or in particular photographic applications. However, without specific context, it is difficult to provide detailed information.

The **centre wavelength** refers to the specific wavelength that is positioned at the midpoint of a spectral range or wavelength band. It is commonly used in various fields, such as optics, telecommunications, and spectroscopy, to define the central value of a range of wavelengths emitted, transmitted, or detected by a device or system.

Cer-Vit is a type of dental ceramic material used in restorative dentistry, particularly for making crowns, bridges, and other dental prosthetics. It is known for its strength, aesthetic qualities, and ability to mimic the natural appearance of teeth. The material is often favored for its biocompatibility, durability, and resistance to wear.

Chinese Optics Letters is a scientific journal that publishes research articles in the field of optics and photonics. It covers a wide range of topics, including but not limited to, optical materials, devices, imaging, laser technology, and photonic applications. The journal aims to provide a platform for researchers to share their findings and advancements in optical science and technology, fostering collaboration and innovation.

The term "Chromatrope" does not refer to a widely recognized concept, object, or term in mainstream knowledge as of my last update in October 2023. It could potentially refer to a specific product, artwork, or concept created after that date or be a misspelling or variation of another term.

In fiber optics, **cladding** refers to the outer optical layer that surrounds the central core of an optical fiber. The core is the light-carrying part of the fiber, typically made of glass or plastic, and it is designed to transmit light signals. The cladding, on the other hand, is made from a different type of glass or plastic material that has a lower refractive index than the core.

The Coefficient of Utilization (CU) is a metric used in lighting design to measure how effectively the light output from luminaires (light fixtures) contributes to the illuminance level on the work surface. It is defined as the ratio of the illumination on a specific surface to the total light output emitted by the luminaries.

Coherence Scanning Interferometry (CSI) is a high-resolution imaging technique that utilizes the principles of interference and coherence of light to obtain detailed, three-dimensional images of a sample. This method is especially prominent in fields like biomedical imaging, materials science, and metrology. Here’s a brief overview of how it works and its applications: ### Principles 1. **Interference of Light**: CSI leverages the interference of light waves that are derived from a common source.

Coherence theory in optics refers to the characteristics of light waves, particularly in terms of their phase relationships. It is a crucial concept in understanding the behavior of light, especially in applications such as interferometry, holography, and various optical technologies. **Key Aspects of Coherence Theory:** 1. **Coherence Length and Time:** - Coherence length is the distance over which a coherent wave (like a laser beam) maintains a predictable phase relationship.

A Coherent Perfect Absorber (CPA) is a device or system that is designed to absorb incoming electromagnetic waves (such as light) completely, without reflecting or scattering any of that energy. It achieves this by using interference effects, where the incoming waves are perfectly matched in phase and amplitude to the waves that are coherently emitted by the absorber. The concept of a CPA is analogous to that of a laser, where energy is emitted coherently.

A "cold mirror" is an optical device designed to reflect visible light while allowing infrared (IR) light to pass through. This is particularly useful in applications such as photography, videography, and scientific instrumentation where it's important to separate these wavelengths. Cold mirrors usually consist of a thin layer of metal or a dielectric coating that reflects certain wavelengths while being transparent to others, effectively achieving thermal management by preventing heat buildup from infrared radiation.
