It is a photographic registration of the interference pattern formed by two laser beams of coherent light.
The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light.
She has shepherded the construction of the Linac Coherent Light Source at the Stanford Linear Accelerator Center and the National Synchrotron Light Source II at Brookhaven National Laboratory.
They have selected 70 papers and organized them into sections that set the foundations of phase-space optics, explore the incorporation of phase-space concepts into the analytical tools for describing optical wave fields and optical systems, describe the use of phase-space representations to analyze and design imaging devices, explore the use of phase-space representation to understand radiometry and partially coherent light, discuss the discrete Wigner distribution, look at optical implementation of phase-space representations, consider issues of optical metrology and signal recovery, translate the description of optical signals and systems into the framework of phase-space representations, and introduce time-domain application and the manipulation of short-time pulses.
The Optical Translation Measurement technology allows for measurement of the relative motion between an OTM sensor and practically any object moving across its optical aperture, using a coherent light source (laser) and an innovative, simple optical set up.

This is the first practical 3-D laser ever produced," says Musevi, who expects that the microdroplet lasers, which can be made by the millions in seconds, will be used in making arrays of coherent light emitters.
The HZB operates at its Berlin offices in Wannsee and Adlershof 2 large scientific equipment for basic research in physics: the neutron source BER II at the Wannsee site provides neutrons for research purposes and the synchrotron radiation source BESSY II allows material analysis with a brilliant, coherent light from the terahertz to in the X-ray range.
Claire Gmachl, who was not involved in the research and is Princeton's Eugene Higgins Professor of Electrical Engineering and a pioneer in the field of semiconductor lasers, said that because lasers, masers and other forms of coherent light sources are used in communications, sensing, medicine and many other aspects of modern life, the study is an important one.
