671nm Laser

Holography can be divided into two processes of recording and reproduction. The recording process is to superimpose the reference light and reflected light on the object onto the holographic plate to create interference fringes. After processing the plate in a dark environment, the interference pattern on the sensor plate is replicated by diffraction to be exactly the same as the original object. Compared with ordinary photography, holography can not only record the amplitude of the light field of the subject, but also the relative phase of the reflected light waves. It is widely used in holographic microscope, holographic anti-counterfeiting, data storage, deformation measurement and holographic interferometer.
