3 LASER SPECKLE NOISE SUPPRESSION SYSTEM AND 3D RECONSTRUCTION METHOD OF OBJECT AGE USING THE SAME

摘要

The present invention maintains the coherence of the laser light source and efficiently reduces the laser speckle by passing the diffuser plate controlled by a predetermined control unit on the imaging surface side after the laser light source passes through the optical interferometer, thereby effectively reducing the laser speckle to digital holographic microscopy technology It provides a laser speckle noise reduction system that can improve the measurement accuracy of and a 3D object shape restoration method using the same.
