Target, ruled line

Ruled Line Target. For the measurement of pincushion distortion, we decided to examine a ruled line target. It turned out that the intensity profiles obtained for these measurements were also useful for evaluation of the distortion caused by the pulsing of the SIT vidicon and also for measurement of channel-to-channel crosstalk. 

The preceding was developed mostly for atomic or molecular targets, and, indeed, much experimental work has been carried on gaseous samples. If one thinks along the lines of the Bragg rule [21], then one would not expect such considerations to differ much from results obtained on solid samples, and for most molecular or van der Waals solids - indeed they do not [22].
