Three-dimensional imaging system

A three-dimensional imaging system is described which exploits the defocusing of non-zero diffraction order images caused by the quadratic distortion of a diffraction grating. An optical system is used such that objects (and ), located at different distances from grating, are imaged simultaneously a...

Zusammenfassung:A three-dimensional imaging system is described which exploits the defocusing of non-zero diffraction order images caused by the quadratic distortion of a diffraction grating. An optical system is used such that objects (and ), located at different distances from grating, are imaged simultaneously and spatially separated on a single plane B.
