In the past month several sets of correction filters have been constructed to
remove two dimensional linear motion but at this time results are inconclusive. We
have been using a new evaluation technique since a valid simulation of a two dimensional
smear is very difficult to generate. However, if the original aberrated impulse response
is used as a target, the filter that was made with it should be a matched filter for that
particular shape, i.e., a successful filter will produce a delta function response when
matched to the smeared impulse response. Although this technique is very sensitive, the
total illumination is so low that a visual evaluation procedure is quite slow and weak res-
ponses from marginal filters are not'always detectable.
Once again we have found it necessary to refine the exposure parameters used
in the filter construction since in the two dimensional case, small exposure changes have
totally changed the filter characteristics. Our best evidence indicates that for each
particular smeared impulse response a unique set of exposures must be found experimen-
tally to obtain a satisfactory filter.
Most of the coming month will be used to generate optimum filters and examples
of filtered imagery for the final report.
As of 1 July 1967, 83% of the contract time has been completed and 74% of the
funding has been expended. It is estimated that approximately 80% of the work is
completed.
