This article introduces an improvement in field of view and resolution in LSFM technology, and demonstrates its effectiveness in three-dimensional high-resolution imaging.
In light-sheet fluorescence microscopy (LSFM) a thin light sheet is used to excite the specimen from the side and imaging is performed in the direction perpendicular to the light-sheet. It has the advantages of fast imaging speed, high optical sectioning capability and low photobleaching and phototoxicity to samples. Therefore, it is suitable for high-quality, long-term three-dimensional dynamic observation of large living biological samples. However, the traditional Gaussian light sheet illumination microscopy technology has the problems of small imaging field of view and low spatial resolution. Based on the existing dual-sided illumination LSFM, a large field of view and high resolution LSFM combined with virtual single-pixel imaging deconvolution is presented in this paper, which improves the field of view and resolution of LSFM simultaneously. The relevant microscope is designed and built, and three-dimensional optical sectioning imaging experiments on fluorescent beads and transgenic zebrafish standard samples are carried out. The experimental results prove the three-dimensional high resolution imaging capability of the microscope, which is of great significance in developing the large field of view and high resolution LSFM.
