Pico 数字光投影仪已被实现为用于共焦成像的集成照明源和空间光调制器。用一系列快速投射的线或点来照明目标以模拟扫描。从目标返回的光被成像到 2D 滚动快门 CMOS 传感器上。通过控制卷帘快门和照明图案之间的时空关系，从目标返回的光被空间过滤。介绍了这种新颖成像技术的共焦视网膜、荧光和傅里叶域光学相干断层扫描实现。
A Pico digital light projector has been implemented as an integrated illumination source and spatial light modulator for confocal imaging. The target is illuminated with a series of rapidly projected lines or points to simulate scanning. Light returning from the target is imaged onto a 2D rolling shutter CMOS sensor. By controlling the spatio-temporal relationship between the rolling shutter and illumination pattern, light returning from the target is spatially filtered. Confocal retinal, fluorescence, and Fourier-domain optical coherence tomography implementations of this novel imaging technique are presented.
