Imaging input/output with shared spatial modulator

摘要

An image input/output apparatus and method includes a light source in optical communication with a spatial radiation modulator for projecting an output image and an image sensor for capturing an input image along a shared input/output path. In a described embodiment, the display of an output image and the capture of an input image is effected using a common spatial radiation modulator (SRM) in the form of a deformable mirror device (DMD).

主权项

1. A method of displaying a first image at a display location and capturing a second image of a subject located proximate the display location utilizing radiation paths having at least partially common paths, wherein the at least partially common paths both include the same spatial radiation modulator; wherein the radiation includes electromagnetic radiation having a frequency in the terahertz region of the electromagnetic spectrum.
