IR Sensor Calibration: When Extreme Uniformity Is Not Boring

Extended area blackbodies are now commonly used as reference sources for IR cameras, simultaneously calibrated. The uniformity of the reference blackbody is therefore essential. A newly developed specific bench measures IR source uniformity with a high accuracy.

CATHERINE BARRAT, HGH INFRARED SYSTEMS INC.

To increase productivity, more and more IR camera manufacturers are developing parallel calibration processes, in which a set of sensors are facing a reference source consisting of a large area blackbody. Consequently, demanding constraints are reported on the specification of the reference source...Read full article
