Patent ID: 10539771

Abstract:
An imaging system is provided, which includes: a microscope; a field diaphragm; a one-dimensional beam-splitting grating, configured to duplicate a beam after passing through the first 4f system into beams with different angles; a phase modulation component, configured to perform different phase modulations to the beams with different angles respectively; a blazed grating, configured to perform dispersion to the beams with different angles passing through the phase modulation component at a dimension orthogonal to the beam-splitting grating; a micro lens array, configured to make the beams with different angles passing through the blazed grating to map to different locations on a back focal plane of the micro lens array; an image sensor, configured to image the back focal plane of the micro lens array. The system may recover three-dimensional information and multispectral information of the sample simultaneously from a single image.
