We present the results of a method for the detectivity simulation of multi-period AlGaAs/GaAs Long-wavelength quantum well infrared photodetectors (LW-QWIPs) directly from the characterized device parameters in a self-consistent way. This simulation method takes into account the fundamental mechanisms involved in the detection process. The electrical field distribution, currents and detectivity are...
A novel night vision enhancement technology based on IR to visible light translation was demonstrated with a specifically designed liquid crystal cell sandwiched with pyroelectric and glass plates, which can be viewed by naked eyes.
