Note: even for timed capture tests, you may want to acquire and analyze a single static image of the specimen before
running the test. This will verify that the test is ready to proceed and there are no problems with the lighting, calibration,
focus, or speckle pattern. This is a good safeguard before running any type of expensive or destructive test and only takes a
few moments. Simply acquire the image; analyze according to the instructions in the following section; and confirm that the
error is low and that the shape looks correct.
