Abstract
Apparatus for imaging a scene, comprising a focusing structure for focusing light emanating from a scene on an imaging subsystem, and an imaging subsystem. The imaging subsystem includes an imager, disposed within the optical path of the focusing structure, having an array of pixels sensitive to light at frequencies higher than far infrared frequencies, and a frequency shifter disposed between the lens element and the imager. The frequency shifter includes an array of frequency-shifting elements disposed over a subset of the array of pixels, the elements shifting the far infrared frequencies from the focused light to higher frequencies and transmitting the resulting signals to the subset of the array of pixels.
