Abstract
An imaging device is specified, the imaging device including a detector array a plurality of pixels, the pixels including a plurality of subpixel types, a micromirror array with a plurality of mirror elements, and an internal light source, wherein at least one of the subpixel types is configured to detect a first radiation; the mirror elements are configured to deflect in response to a second radiation, the internal light source is configured to illuminate the detector array with a third radiation; at least one of the subpixel types is configured to detect the third radiation deflected by the micromirror array. Furthermore, a method of multi-spectral imaging is specified.
Claims21
An imaging device comprising:
- a detector array with a plurality of pixels, the pixels comprising a plurality of subpixel types,
- a micromirror array with a plurality of mirror elements, and
- an internal light source, wherein
- at least one of the subpixel types is configured to detect a first radiation wherein the first radiation includes radiation in the visible spectral range and comes from a scene to be imaged by the imaging device;
- the mirror elements are configured to deflect in response to a second radiation,
- the internal light source is configured to illuminate the micromirror array with a third radiation;
- at least one of the subpixel types is configured to detect the third radiation deflected by the micromirror array.
(canceled)
A method of multi-spectral imaging comprising including
- a) providing an imaging device comprising:
- a detector array with a plurality of pixels, the pixels comprising a plurality of subpixel types,
- a micromirror array with a plurality of mirror elements, the mirror elements being configured to deflect in response to a second radiation, and
- an internal light source;
- b) obtaining a first image using at least one subpixel type responsive to a first radiation, wherein the first radiation includes radiation in the visible spectral range and comes from a scene to be imaged by the imaging device;
- c) illuminating the micromirror array with a third radiation emitted by the internal light source;
- d) detecting the third radiation reflected by the micromirror array using at least one subpixel type responsive to the third radiation;
- and
- e) obtaining a second image corresponding to the second radiation based on the detected third radiation.
