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.
