ABSTRACT:
Imaging that uses glare to confirm proper measurement of a sample. An imaging device illuminates an object and generates glare (i.e., specular reflection, diffuse reflection or a combination of the two) off the object's surface, which is displayed on a display as a glare artifact. The location of the glare artifact is compared to a predetermined location to establish adjustment to obtain a desired angular orientation. The imaging device optionally highlights the glare artifact and steers a user to obtain the desired presentation angle. In two other embodiments, the spatial relationship between the imaging device and the object is time-varied. In one, the imaging device monitors changing glare and acquires a measurement when a desired glare is detected. In the other, the imaging device captures multiple images including varying glare artifacts and analyzes the images to select a preferred image having a glare artifact indicative of a desired angular orientation.
