Abstract
Techniques are disclosed for facilitating multiple microbolometer selection for simultaneous readout. In one example, a device includes a plurality of microbolometers. The plurality of microbolometers includes a first set and a second set of serially-connected microbolometers. The device further includes a first plurality of switches configured to selectively short the plurality of microbolometers. The device further includes a second plurality of switches configured to selectively couple the plurality of microbolometers to ground. The device further includes a third plurality of switches configured to selectively provide a bias signal to the plurality of microbolometers. The device further includes a processing circuit configured to configure the first plurality, second plurality, and third plurality of switches to cause simultaneous read out of one microbolometer of the first set and one microbolometer of the second set. Related methods and systems are also provided.
