Testing of coherent optical data processing systems has shown a need for a method which measures resolution at all points in the image format. The use of multifrequency linear gratings as test objects satisfies this need. Quantitative data may be obtained if care is taken to calibrate and linearize the photographic process. However, the method’s principal application seems to be for qualitative testing. A comparison is made between calculated wavefront aberrations and experimental results obtained using linear gratings.
