Abstract:
The present invention provides a multi-mode calibration target operable to calibrate multiple optical sensors. One embodiment has multiple planar surfaces, wherein the multiple planar surfaces are able to be distinguished by visual sensors based on their color, hue, shade, tint, or tone. Additionally, these planar surfaces may be raised or recessed from one another to provide depth contrast as well as visual contrast. Other embodiments may include narrow band emitters such as laser diodes located at predetermined locations within the multi-mode target. These targets may then be used to calibrate various sensors, such as optical sensors, within an inspection system such as a laser ultrasonic inspection system.
