Heimann Global Shutter
While ALL microbolometer infrared cameras operate with a rolling shutter, thermopile arrays have the option to be used in global shutter mode.
This is possible due to the architecture of the signal conditioning and AD-conversion. All Heimann array sensors are build of separate "blocks". All pixels from one block can be read at the same moment in time. And this global shutter option can be very fast compared to reading the whole array.
E.g. the 8x8 array consists of 1 single block and all 64 pixels are read at the same time. The 60x40 on the other hand consists of 5 separate blocks and usually you read the array block by block. In global shutter mode, you can read only the inner block of 60x8 pixels, but at 5 times higher framerates. So instead of standard 21 Hz you can read a single block in global shutter mode with more than 100 Hz.
This makes thermopile arrays suitable for fast scanning applications e.g. in production environments inspecting heat seals or detection and counting of fast moving (hot) objects.
