Abstract
An optical smart sensor combines a phase grating with a rolling shutting to distinguish between modulated point sources. Employing a phase grating in lieu of a lens dramatically reduces size and cost, while using timing information inherent to imaging techniques that used a rolling shutter allows the smart sensor to distinguish point sources quickly and easily using a single frame of image data.
