Patent ID: 8890072

Claim:
A system comprising: a first micro-mirror device including a surface having a plurality of micro-mirrors movable to reflect light incident to the micro-mirrors in at least a first direction and a second direction; a control circuit configured to arrange the micro-mirrors to project a spatial image using the incident light and to generate spectral content for the spatial image to form a simulated target model containing both spatial information and spectral information, the spectral content including light having one or more wavelengths outside a range of wavelengths for visible light; and a spectrometer circuit configured to extract spectral image information from the generated spectral content and provide the spectral image information to the control circuit, wherein the control circuit is configured to, based on the extracted spectral image information, rearrange one or more micro-mirrors of the micro-mirror device to tune spectral content of the target model closer to specified target spectral image information.
