Non-interference parallel OCT imaging system based on digital microscope device

This utility model discloses one DMD-based (digital micromirror device) crosstalk-free parallel optical coherent tomography (OTC) imaging system. This system realizes face illumination with broadband point source. One DMD is added in the lighting path. Optical system design is adopted to ensure that the micromirror transverse scale on the sample conjugate planes is equivalent to the sample transverse scale distinguishable to the system. The micromirror is in the ''open'' state and introduces the corresponding part in the light source into the interference system when it is at an angle of plus 12 degrees. Comparing the DMD codes to change the parallel state of interferometric imaging can effectively restrict the signal crosstalk inherent to organism parallel imaging. Sinusoidal phase modulation and four-stage integral detection method are combined to obtain interference signals. This utility model is characterized by simple system structure, simple and highly efficient coding mode and fast acquisition of signals and there is no need for image mosaicking. Heavy-duty light source can be used.
