Abstract
A color scannerless range imaging system includes an illumination system for controllably illuminating a scene with modulated illumination and an image responsive element for capturing image light from the scene, including the modulated image light. The system establishes a primary optical path for directly image light toward the image responsive element. A beamsplitter located in the primary optical path separates the image light into two channels, a first channel including an infrared component and a second channel including a color texture component, whereby one of the channels traverses a secondary optical path distinct from the primary path. A modulating element is operative in the first channel to receive the infrared component and a modulating signal, and to generate a processed infrared component with phase data indicative of range information. An optical network is provided in the secondary optical path for recombining the secondary optical path into the primary optical path such that the processed infrared component and the color texture component are directly to the image responsive element.
