Abstract: The three-dimensional microscopic imaging system includes: a microscope; a field diaphragm; a narrow-band filter, configured to perform narrow-band filtering; a beam-splitting grating, configured to duplicate a beam into beams with different angles; a lens array with different focal length, configured to perform different phase modulation to each beam with different angles; a micro lens array, configured to modulate the beams with different angles that pass through the lens array with different focal length respectively to different spatial locations at a back focal plane of the micro lens array respectively; and an image sensor configured to record an image corresponding to the modulated beams at the back focal plane of the micro lens array. The system has a simple structure, a cheap cost, and a relatively weak exciting light, and is suit for living samples, and has the adjustable intervals of imaging depths.

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.
