Integrated switch and shutter for calibration and power control of infrared imaging devices

Abstract

Various devices including a three-stage switch and an infrared (IR) imaging module and methods for performing FFC using the three-stage switch and the IR imaging module are provided. The three-stage switch may have at least a first position in which the IR imaging module is powered off, a second position in which the IR imaging module is powered on and the shutter is positioned in the FOV, and a third position in which the IR imaging module is powered on and the shutter is positioned out of the FOV, wherein the second position is intermediate in relation to the first position and the third position. A thermal image of the shutter may be captured while the switch is at or adjacent to the second position, and an FFC map of FFC terms may be acquired based on the thermal image of the shutter.

Dependencies are inferred from the claim text.
