Texas Instruments DLP4500 数字微镜器件
Texas Instruments DLP4500 数字微镜器件(DMD)是一款数控 MOEMS（微光机电系统）空间照明调制器(SLM)。当与适当的光系统结合使用时，TI DLP4500可用于调制进入光的振幅和方向。DLP4500生成具有速度、精度和效率的光图样。从架构上来讲，DPL4500 是一款可锁存、电进/光出半导体器件。这个架构使得 DLP4500非常适合于使用结构光的3D扫描或度量、扩增实境、显微镜、医疗仪器和光谱分析等应用。DLP4500紧凑的物理尺寸非常适合于注重小外形尺寸和较低成本的便携式设备。DLPC350数字控制器是DLP 0.45 WXGA芯片组的一部分，它能够支持DLP4500数字微镜器件的可靠运行。
