20160111587 | INFRA RED DETECTORS AND METHODS OF MANUFACTURE - A method of forming infra red detector arrays is described, starting with the manufacture of a wafer. The wafer is formed from a GaAs or GaAs/Si substrate having CMT deposited thereon by MOVPE. The CMT deposited comprises a number of layers of differing composition, the composition being controlled during the MOVPE process and being dependent on the thickness of the layer deposited. Other layers are positioned between the active CMT layers and the substrate. A CdTe buffer layer aids the deposition of the CMT on the substrate and an etch stop layer is also provided. Once the wafer is formed, the buffer layer, the etch stop layer and all intervening layers are etched away leaving a wafer suitable for further processing into an infra red detector. | 04-21-2016 |

20110037855 | INFRA RED DETECTOR SYSTEM AND METHOD - A detector system is described in which an image of a scene is displaced with reference to a dual waveband detector array. Such ‘scanning’ increases the sampling density, thereby reducing the effective pixel pitch, by moving the image of the scene relative to the detector array by fractions of a pixel pitch in sequential frames.

A detector, detects the reflected radiation pulses and outputs signals characteristic of the scene to an imaging device or camera.
