Portable uncooled shutterless camera operating in the long-wavelength infrared range. Part II: Digital image processing

This work consists of two parts and describes an original portable Long-Wavelength Infrared Range (LWIR) camera, which was developed based on a commercial uncooled bolometric matrix and aided by few approaches, aimed at the image acquisition improvement. In the second part of our paper, we focused on numerical methods applied for compression of the dynamic range, enhancement of the image details, and suppression of image noises. These algorithms were implemented in a hardware using the Field-Programmable Gate Array (FPGA) and the high-speed double data rate Synchronous Dynamic Random Access Memory (SDRAM). In our opinion, the described camera is capable of solving numerous demanding problems of IR optics and biophotonics.
