Abstract

The present invention solves a problem of back-reflections from a digital micromirror device (DMD) and optical path allignment when a DMD device is used in confocal microscopy to generate multiple spots on a sample (sample), as well as to act as an array of pinholes for registering the light reflected from the sample (sample). The working area of a single DMD devixe is split into two separate parts of the DMD working surface area, which are independently controlled: one part (illumination part) is used to generate an array of spots, while the second part (detection part) is used to act as an array of pinholes directing the light reflected from the sample (sample) to the image registering device (camera). Such spatial separation of the two parts of the DMD prevents the back-reflection from DMD reaching a detector or the image registering device (camera). Furthermore, using a single DMD device (DMD) for both light beam paths allows perfect allignment of the optical layout and light beam paths, thereby, implementing the confocal microscopy function more simply and efficiently.
