VGA 17-micron uncooled infrared imaging sensor has a 24.13×24.13×5.57mm footprint
This translates into a uniform pixel factor of merit (400 mK.ms). Thermal sensitivity or NETD (Noise Equivalent Temperature Difference) shows how well pixels convert input signals (IR light/thermal radiation) into voltage in proportion to the thermal radiation emitted by an object: the higher the thermal sensitivity, the better the image.
Thermal time constant refers to the speed at which pixels respond to input signals. For IR microbolometers, a low thermal time constant enables lag-free images. The device can perform long-range detection up to approximately 2km, depending on the target, as well as detect fast-moving objects.
The Pico640E’s high performance makes it suitable for image-fusion applications, which use both visible and IR images, minimizing the delay between visible and IR images when they are superimposed.
