LEOK-50 Information Optical Experiments with LC-SLM


  • Open structure to enhance students' hands-on skills and deepen their understanding of experimental principles
  • Powerful software for holographic encoding transform of images and their reconstruction
  • Measurement of electro-optic effect of liquid crystal materials
  • Comprehensive experimental instructions


Liquid crystal (LC) is an organic polymer compound that may flow like a liquid, but the molecules may be aligned in a crystal-like orientation. When LC molecules are aligned, the material becomes optically anisotropic. A LC screen is a spatial light modulator (SLM) based on the electro-optic modulation property of the LC material. This type of modulator is electronically addressable so that both input and output signals of the device can be computer-controlled. A LC-SLM can be used for optical signal processing, such as computed holography. It is suitable for optical experiment education in opto-electronic information, physics and other related areas.
