Abstract

For acquiring optically sectioned images of volumetric samples from multiple depths without axial scanning, a confocal system which is able to obtain multi-plane images with a Digital Micro-Mirror Device (DMD) has been proposed. The focal points of the laser beam can be arbitrarily positioned to any multiple planes in the three dimensional object space by switching multiplexed binary hologram encoded in the DMD by Lee hologram. The radius of the spherical wavefronts generated directly determines the location of the focal points and DMD can function either as a convex or concave mirror. The optical sectioning capabilities of system are verified and which can be applicable in various biomedical imaging applications.
