= Phase-coherent holography
{wiki=Phase-coherent_holography}
Phase-coherent holography is an advanced technique in optical imaging and measurement that combines principles of holography with coherent light sources to capture both the amplitude and phase information of light waves. In traditional holography, an interference pattern is used to record the light field generated by an object and a reference beam. This interference pattern encodes both the intensity (amplitude) and phase information of the light.
