The piezooptic effect refers to the change in the optical properties of a material when it is subjected to mechanical stress. Specifically, it describes how the refractive index of a material changes in response to applied pressure or strain. This effect is particularly important in materials that exhibit both piezoelectric and optical properties, such as certain crystals and polymers.

A plasmat lens is a type of lens that utilizes plasma—a state of matter consisting of ionized gas—rather than traditional materials like glass or plastic to focus light. Plasma lenses can manipulate light in novel ways and have applications in areas like optics, laser technology, and advanced imaging systems.

A polychromator is an optical device used to separate and analyze light into its component wavelengths or colors. It works by dispersing incoming light into a spectrum, which can then be measured or analyzed for various applications in fields such as spectroscopy, astronomy, and metrology. Polychromators typically utilize diffraction gratings, prisms, or filters to achieve this dispersion.

The Proceedings of SPIE is a series of published volumes that contain the papers presented at various conferences organized by the Society of Photo-Optical Instrumentation Engineers (SPIE). SPIE is an international society dedicated to advancing light-based sciences and technologies, including optics, photonics, and imaging. The Proceedings of SPIE serves as a platform for researchers, engineers, and industry professionals to share their work and discoveries in a peer-reviewed format.

She has been involved in both theoretical and experimental aspects of accelerator physics and has contributed to public engagement and science communication, emphasizing the importance of fundamental research in advancing technology and understanding the universe. Additionally, she has gained recognition for her outreach efforts, aiming to inspire and educate the next generation of scientists.

Tord Ekelöf could refer to a person with that name, but there isn't a widely recognized public figure or concept by that name as of my last knowledge update in October 2023. If you have more specific context, such as a field (like art, science, sports, etc.

As of my last update in October 2021, there is no widely known or notable figure named Vanina Ruhlmann-Kleider. It's possible that she could be a private individual or someone who gained prominence after that date.

A Severi–Brauer variety, named after the mathematicians Francesco Severi and Hans von Brauer, is a specific type of algebraic variety that is related to the study of division algebras and central simple algebras in algebraic geometry.

The Cancellation Property is a concept often used in mathematics and various fields, including algebra and logic. It refers to a specific situation where an operation or a relationship between elements allows for the removal or "cancellation" of certain terms without affecting the overall truth or outcome of the equation or expression. In mathematics, particularly in algebra, the cancellation property can be illustrated as follows: 1. **Cancellation in Addition**: If \( a + c = b + c \), then \( a = b \).

A fixed-point theorem is a fundamental result in various branches of mathematics, particularly in analysis and topology, that asserts the existence of fixed points under certain conditions. A fixed point of a function is a point that is mapped to itself by the function. Formally, if \( f: X \rightarrow X \) is a function on a set \( X \), then a point \( x \in X \) is a fixed point if \( f(x) = x \).

A reference surface is a baseline or standard surface against which measurements or comparisons are made. The term can be used in different contexts, including engineering, geodesy, fluid dynamics, and more.

Yablonovite is a rare mineral that is a member of the zeolite group. It is primarily composed of aluminum, silicon, and oxygen, and it is characterized by its unique crystal structure and properties. Yablonovite was discovered in the 1980s and is named after the Russian geologist A. Yablonov.

A zero-mode waveguide (ZMW) is a type of optical structure used primarily in the field of nanophotonics, particularly for the study of single-molecule interactions and fluorescence microscopy. The concept is often applied within the context of techniques such as single-molecule spectroscopy.

An appoggiatura is a musical ornament or embellishment that typically involves a non-harmonic tone (a note that is not part of the chord being played) that approaches a main note (the principal note) by a leap, usually in the opposite direction. The appoggiatura is usually accented, meaning that it is given more emphasis than the subsequent main note, and it is often resolved down to the main note.

Bebung is a term that refers to a specific style of ornamentation in Indonesian gamelan music, particularly in the performance of the central Javanese gamelan. It involves a type of vibrato technique used by musicians playing traditional instruments, such as the gender (a metallophone) and other related instruments. Bebung adds expressiveness and emotional nuance to the music, enhancing its overall aesthetic and making it more dynamic.

Diminution generally refers to the process of becoming smaller or less in amount, value, quality, or intensity. The term can be applied in various contexts: 1. **General Use**: In everyday language, it simply denotes a reduction or decrease in size or degree. 2. **Legal Context**: In legal terms, diminution often refers to a decrease in property value due to factors such as damage, market conditions, or other external influences.
