The invention relates to a
structured light quick scanning
microscopic imaging method. The method comprises the following steps of: (1) controlling a
spatial light modulator to generate a
modulation pattern with single
spatial frequency by a computer, and projecting the
modulation pattern on a sample fracture; (2) under the condition that the phase of the
modulation pattern is unchanged, driving a sample to move by an
electric control movement platform, and synchronously triggering a line-scan
digital camera to take a picture; (3) changing the phase of the modulation pattern, and scanning the same imaging region until different lighting phase images required by
structured light imaging is acquired; and (4) moving a sample, and executing the steps (2) to (4) for the subsequent adjacent imaging region until the whole sample fracture is scanned. By performing
phase change for one time before scanning motion is performed at each time, requirements of imaging on the speed and robustness of the modulator are reduced; and in single-time scanning motion, a complete image is acquired, and adjacent images are partially overlapped. Sample motion and camera
exposure are synchronously performed, so that time is saved, and imaging speed is increased.
