An infrared imaging system having functionality for maintaining image quality in the presence of temperature drift of the system. Such functionality is applied repetitively to maintain image quality of a target scene, yet without continuous actuation of a shutter of the system. The functionality of the imaging system results from implementing an imager algorithm. In use, the imager algorithm functions with a calibration curve created for the imaging system, with the curve comprising a plot of system output versus target scene temperature.

Shutterless infrared imager algorithm with drift correction

A thermal imaging apparatus includes an infrared camera module, aligned along a first axis, and a visible light camera module, aligned along a second axis. The apparatus employs a magnification correction factor, along with parallax correction, to register an infrared image, obtained by the infrared module, with a visible light image, obtained by the infrared module.

Registration methods for fusing corresponding infrared and visible light images

A thermal imaging apparatus comprises a thermal image camera having a lens and a display. The camera further includes a focal plane array located behind the lens for converting imaging radiation to produce an image signal for further processing. A shutter mechanism is operative to selectively inhibit exposure of the focal plane array to the imaging radiation such that the focal plane array produces a reference signal. Processing circuitry is operative to receive the image signal and produce a corresponding thermal image on the display. The processing circuitry is further operative to utilize the image signal and the reference signal to derive temperature information.
