The spatial light modulator (SLM) used in the holographic projection display system is essentially an optoelectronic device, which can change the amplitude, phase, polarization and direction of the wavefront. The system has the characteristics of high flexibility and good innovation.

The supporting software of UPOLabs digital holographic optical experimental system can realize computational holography and optical reproduction. It can also use optical recording holography to perform digital reproduction or optical reproduction. Through this system, the knowledge of information optics can be linked together, and the Fourier transform in information optics can be fully explained. important role in.
