SFG Series Digital Micromirror Spatial  Light Modulators

We are mainly engaged in the application  technology research and development of digital micromirror spatial light  modulator (Digital Micromirror Device-DMD). It is a high-tech enterprise  specializing in the research and development, production and sales of hardware  and software in digital light process (DLP) related fields such as  semiconductor maskless lithography, computational imaging, compressed sensing  and 3D detection. Our products include SFG-F3010, SFG-F4100, SFG-F4200, SFG-F4500,  SFG-F4710, SFG-F4320, SFG-F6500, F SFG-9000, etc., widely used in scientific  research, 3D scanning and LDI industries.

The company has been composed of young and  middle-aged technical backbone R & D team, can be said to provide customers  with DLP scheme design, DMD drive control system design and other services. At  the heart of the digital micromirror spatial light modulator is the digital  Micromirror device (DMD), an optical semiconductor module and a MEMS chip in  which each lens can be deflected ±10deg, ±12deg or ±17deg respectively, around the hinged shaft.  The DMD chip mainly regulates the rotation Angle of each micromirror on the  chip according to different digital signals transmitted by the front-end  circuit to the CMOS chip, so that the light irradiated on the micromirror can  be selectively reflected to the imaging surface for imaging. Since the  deflection of the lens is controlled separately by the underlying CMOS control  circuit and the binary information of the reset signal of the lens, the optical  field digital flower modulation can be realized. Because DMD is reflected by  aluminized micromirror, almost no energy absorption, and controlled by CMOS technology,  the speed, accuracy, energy and efficiency of light modulation are far more  than other spatial light modulators. DMD technology is widely used, including  spectral analysis, maskless lithography, 3D measurement, naked eye 3D display,  holographic imaging, compressed sensing, biological microscopy, SLA 3D  printing, machine vision, etc.

Operation Principle  of Digital Micromirror Devices:

At heart of the Digital Micromirror spatial  light modulator is the Digital Micromirror device (DMD), an optical  semiconductor module and a MEMS chip in which each lens can be deflected ±10°,  ±12°, or ±17.5°, respectively, around the articulated shaft. The DMD chip mainly  regulates the rotation angle of each micro mirror on the chip according to  different digital signals transmitted by the front-end circuit of the CMOS  chip, so that the light shin on the micro mirror can be selectively reflected  on the imaging surface for imaging. Since the deflection of the lens is  controlled solely by the underlying CMOS control circuit and the binary  information of the lens reset signal, the digital modulation of the optical  field can be realized. Because DMD is reflected by aluminized micro mirror,  almost no energy absorption, and controlled by CMOS technology, the speed,  accuracy, energy and efficiency of light modulation is far higher than other  space light modulators. DMD technology is widely used, including spectral  analysis, maskless lithography, 3D measurement, naked eye 3D display,  holographic imaging, compressed sensing, biological microscopy, SLA 3D  printing, machine vision, etc.
