摘要： A surface roughness measurement device that in one embodiment includes main and auxiliary emitting fibers, multiple collecting fibers, an optical housing, main and auxiliary reflective mirrors, and an external circuit. The optical housing includes the fibers and defines an aperture for optically contacting a surface of an object. The main reflective mirror is arranged in the optical housing, for reflecting light emitted from the main emitting fiber to a detecting point of the aperture and reflected light by the object to the collecting fibers. The auxiliary reflective mirror is arranged in the optical housing, for reflecting light emitted from the auxiliary emitting fiber to the detecting point. The external circuit is for generating a laser beam to the main and auxiliary emitting fibers, collecting the reflected light from the collecting fibers, and calculating the surface roughness of the object based on the collected reflected light.

摘要： A method involves receiving a test image of at least a portion of a test object which includes a test moiré pattern generated by superposing one or more reference gratings on one or more subject gratings. The method further involves analyzing one or more test beat lines in the test moiré pattern and calculating one or more test values based on the analysis of the one or more test beat lines. The one or more test values are a function of one or more rotational angles corresponding to the one or more subject gratings and a shape of at least the portion of the test object. The method also involves calculating one or more angular errors of the one or more subject gratings based on the one or more test values and one or more template values and sending a notification based on the one or more angular errors.
