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 system for displaying and capturing images, comprising:
a radiation source; a spatial radiation modulator positioned to receive radiation from the radiation source and direct the radiation for display of at least portions of an image to a display location, responsive to first position settings of individually addressable radiation reflecting members of the spatial radiation modulator; and a radiation sensor positioned to capture at least portions of an image of a subject positioned adjacent the display location, said spatial radiation modulator positioned to receive radiation from the display location and direct the received radiation to the radiation sensor responsive to second position settings of the individually addressable radiation reflecting members; wherein the image is displayed on one side of an imaging display surface for viewing from an opposite side of the surface; and the system further comprises a switchable diffusion screen for coordinated switching of a diffusion characteristic for capture of an image of a subject on the opposite side of the surface.
