Ultra-High speed 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.
