It has done so in the past. But one problem with the circle-in-the-square test is that it measures scanner performance at only one point in the scanner鈥檚 performance regime. This is like measuring a loudspeaker鈥檚 performance by the accuracy at which it plays middle C. While helpful, it does not tell the whole story.

        Measuring at one point has worked so far because in the past the scanner performance curve has been similar at 12K, 30K and even 36K. If performance is known at one point, it can be inferred at most other points.

        But new scanners or scanner amp tunings may come out which change the shape of the curve. For this reason, it may be necessary for the laser display industry to develop a consensus on new test patterns that give additional data.
