Abstract
A method and system for imaging a target scene using a microbolometer array having multiple lines of microbolometer pixels are disclosed. Each line is switchable between an exposed state and a shielded state, where the line is exposed to the target scene and a reference scene, respectively. The method may include alternating between generating a target frame of the target scene and generating a reference frame of the reference scene, each of which in a rolling shutter mode. The method may also include, concurrently with the generating steps, alternating between sequentially shielding each line after its readout in the exposed state for its next readout in the shielded state, and sequentially exposing each line after its readout in the shielded state for its next readout in the exposed state. The method may also include adjusting the target frames using the reference frames to generate thermal images of the target scene.
