Phase Gratings with Odd Symmetry for Lensed Optical Sensing

摘要: A sensing device with an odd-symmetry grating projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, are in focus for range wavelengths and spacings. The captured by array, photographs other image information can be extracted from resultant data. Used conjunction converging optical element, versions these gratings provide depth about objects imaged scene. This computationally obtain map
