Embodiment Construction
[0010] As shown in Figure 1 (a), the reflective digital holographic microscopic imaging device based on the telecentric optical structure of the present invention includes a laser 1, a collecting mirror 2, a pinhole diaphragm 3 of the collecting mirror, a first collecting mirror 4, and a first plane mirror 10. The second beam splitter 11, the lens tube lens 12, the microscope objective lens 13, the camera 15, the first attenuation sheet 18 and the second plane mirror 19, the pinhole diaphragm 3 of the condenser lens is placed behind the condenser lens 2 The position of the focal plane is also the position of the front focal plane of the first condenser lens 4; where the laser light emitted by the laser 1 is converged to the pinhole diaphragm 3 of the condenser mirror through the condenser mirror 2, and the light is diverged by the pinhole diaphragm 3 of the condenser mirror and then absorbed by the first The condenser lens 4 collects and becomes parallel light, and then is refl...
