Infrared focal plane arrays

Circuit de Détection (CD) ; detection circuit

Infrared matrix detector brick absorbing incident radiation and generating an electrical signal.

Circuit de Lecture (CL); Read-Out Integrated Circuit (ROIC)

Integrated circuit for reshaping the electrical signal generated by the detection circuit to obtain a video signal.

quantum efficiency; Quantum Efficiency (QE)

Efficiency with which a quantum detector converts photons into electrons.

Noise Equivalent Temperature Difference (NETD)

Merit function quantifying the thermal sensitivity of a camera (and, by extension, of an infrared detector); it is the blackbody temperature variation generating a signal variation equal to the temporal noise.
