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.

Abstract: Techniques are disclosed for systems and methods for facilitating infrared imaging in multiple imaging modes. A device may include an infrared image capture circuit and at least one processing circuit. The infrared image capture circuit may be configured to detect first infrared data and generate a first pixel value based on the first infrared data and a first imaging mode among multiple imaging modes. The at least one processing circuit may be configured to compare the first pixel value to a set of saturation threshold values associated with the first imaging mode. The at least one processing circuit may be further configured to select an imaging mode among the multiple imaging modes based on the comparison of the first pixel value. The at least one processing circuit may be further configured to set the infrared image capture circuit to generate a second pixel value based on the selected imaging mode.

Abstract: Various techniques are disclosed for bolometer circuits and related methods for thermal imaging in a difference domain, where each pixel value represents a difference in incident IR radiation intensity between adjacent bolometers. For example, a bolometer circuit may include an array of bolometers each configured to generate a pixel signal in response to a bias and incident infrared radiation. Each column of the bolometer array may comprise an amplifier, a first plurality of switches each configured to selectively provide a supply voltage to a respective one of bolometers of the each column, a second plurality of switches each configured to selectively route a difference of the pixel signals of a respective adjacent pair of the bolometers of the each column to an input of the amplifier, and a third plurality of switches configured to selectively provide a common voltage to a respective one of the bolometers of the each column.
