A infrared radiation detector array for providing an image signal of a scene is provided including a plurality of infrared radiation detectors having infrared radiation responsive elements. Each one of the plurality of infrared radiation detectors provides a proportionate electrical signal in response to infrared radiation of the scene incident thereto. At least one blind infrared radiation detector having a radiation responsive element is provided and shielded from infrared radiation of the scene. The blind infrared radiation detector provides a proportionate electrical signal in response to infrared radiation incident thereto. The blind infrared radiation detector is configured to provide a signal indicating thermal distortion of the infrared radiation detector array.

Uncooled IR detector array having improved temperature stability and reduced fixed pattern noise

A method of adjusting the position of a micro-mechanical bi-material cantilever is provided. The bi-material includes a first and a second material and each material has a corresponding thermal expansion coefficient. The method includes implanting ions predominantly into one material of the bi-material to modify internal stress in one of the first and second materials relative to the other material. The deformation of the bi-material is then detected to modulate the implantation of ions thereto.
