摘要： A video projector device includes a visible light projector to project an image on a surface or object, and a visible light sensor, which can be used to obtain depth data regarding the object using a time-of-flight principle. The sensor can be a charge-coupled device which obtains color images as well as obtaining depth data. The projected light can be provided in successive frames. A frame can include a gated sub-frame of pulsed light followed by continuous light, while the sensor is gated, to obtain time of flight data, an ungated sub-frame of pulsed light followed by continuous light, while the sensor is ungated, to obtain reflectivity data and a background sub-frame of no light followed by continuous light, while the sensor is gated, to determine a level of background light. A color sub-frame projects continuous light, while the sensor is active.

摘要： A method for encoding information that is encoded in spatial variations of the intensity of light characterized by a first wavelength in light characterized by a second wavelength, the method comprising: transmitting the first wavelength light through a photo-conducting material in which electron-hole pairs are generated by absorbing photons from the first wavelength light to generate a first density distribution of electrons homologous with the spatial variations in intensity of the first wavelength light; trapping electrons from the first electron density distributions in a trapping region to generate an electric field homologous with the density distribution in a material that modulates a characteristic of light that passes therethrough responsive to an electric field therein; transmitting a pulse of light having sufficient energy to generate electron-hole pairs in the photo-conducting material through the modulating material and thereafter through the photo-conducting layer to generate a second additional electron density homologous with the first electron density distribution; trapping electrons from the second electron density distribution in the trapping region; and transmitting the second wavelength light through the modulating material thereby modulating the second wavelength light in response to the electric field and encoding it with the information.
