DLP 0.45 WXGA DMD - DLP4500




The DLP4500 digital micromirror device (DMD) is a digitally controlled MOEMS (micro-opto-electromechanical system) spatial light modulator (SLM). When coupled to an appropriate optical system, the DLP4500 can be used to modulate the amplitude and/or direction of incoming light.  The DLP4500 creates light patterns with speed, precision, and efficiency.

Architecturally, the DLP4500 is a latchable, electrical-in/optical-out semiconductor device. This architecture makes the DLP4500 well suited for use in applications such as 3D scanning or metrology with structured light, augmented reality, microscopy, medical instruments, and spectroscopy. The compact physical size of the DLP4500 is well-suited for portable equipment where small form factor and lower cost are important.  The compact package compliments the small size of LEDs to enable highly efficient, robust light engines.

The DLP4500 is one of two devices in the DLP 0.45 WXGA chip set (see ). Proper function and reliable operation of the DLP4500 requires that it be used in conjunction with the DLPC350 controller. See the DLP 0.45 WXGA Chip-set data sheet (TI literature number DLPU009) for further details. shows a typical system application using the DLP 0.45-inch WXGA chip set.
