In the laser display industry, the ILDA Test Pattern is generally recognized as the standard of comparison. A computer might be able to output the points in the ILDA Test Pattern at 60,000 points per second (or more), and the scanner might show most of the ILDA Test Pattern acceptably, but this is not sufficient -- some of it is unacceptable.

        If someone says 'this scanner shows the ILDA Test Pattern at such-and-such a speed and angle', laserists reasonably assume that the scanner correctly shows all parts of the test pattern (unless explicitly stated otherwise).
