Xix. Neurophysiology A. New Methods for Testing Camera Lenses (part Ii)

In Quarterly Progress Report No. 73 (pages 209-216) we described a new method for testing camera lenses and cameras. This method, which makes use of an especially designed analyzer lens placed in front of the camera lens, together with a polar coordinate test chart, permits simple diagnosis of the focal properties of the lenscamera combination. In particular, our method was shown to be sensitiv...
