KB ViTA kindly sent me an info about their latest LWIR camera that senses polarization: " It all was started with the fact KB ViTA has developed a very sensitive thermal imaging module VLM640, which had a sensitivity of at least 20 mK in 8 — 12 µm band. The sensor manufacturer turned to KB ViTA and offered an engineering sample from an experimental wafer of bolometric detectors with integrated polarization filters. For KB ViTA it was honorable but, at the same time, there was no understanding of what it is expected to ultimately obtain. The technology and the very idea of seeing the own polarization of the thermal photons of objects that surround us is absolutely new and hardly anyone has experience of processing such information. Below we will show you how the polarization in the IR spectrum looks. There were a polarizing sensor and electronics from VLM640 camera with 20 mK sensitivity. The interesting thing about the sensor is each pixel in the group of four is covered with a p...
