Increasing sensitivity of optical gas imaging cameras

7th January 2016


High Sensitivity Mode (HSM) is a technological innovation developed by FLIR Systems to enhance the leak detection performance of their GF-Series optical gas imaging cameras.

FLIR's High Sensitivity Mode is based upon an image subtraction video processing technique that effectively enhances the thermal sensitivity of the camera. The HSM feature subtracts a percentage of individual pixel signals from frames in the video stream from the subsequent frames, thus enhancing the differences between frames, which make leaks stand out more clearly in the resulting images. Using the high sensitivity mode even the smallest of gas leaks can be spotted using a FLIR GF Series optical gas imaging (OGI) camera.

FLIR GF Series OGI camera's offer non-contact measurement of gas leaks in real time. Where many other measuring instruments only present users with a number, GF Series OGI cameras present visual information, making the leak detection process more intuitive.

Optical gas imaging cameras can also be used in hard-to-access locations, since they can detect small leaks from a distance. Unlike restricted point measurement provided by 'gas sniffers' a GF Series OGI camera allows you to detect gas leakage anywhere within the field of view of the camera. This speeds up the process of inspection for gas leaks considerably.
