Paper Abstract

In the manufacture of small primary and secondary replicated mirrors used in tactical missiles one of the most critical decisions is when to accept a master to be used for the replication process. A method has been developed whereby actual measured data on each master can be input to the ACCOS V optical design program so as to appropriately distort the ideal mirror design contour in such a manner as would result from the use of these masters. The resultant image can then be evaluated in terms of blur circle diameter, MTF or whatever other convenient image evaluation criteria one may wish to use. To accomplish this task a program was written to accept the measured data from the masters and translate it into a form compatible with the SPLINE subroutine input format for each mirror. Once this was accomplished normal ACCOS V evaluations were performed. An example is given to demonstrate the steps needed to achieve the above evaluation, including SPLINE curve fitting, interpolation, input sequencing, storage manipulations and image quality evaluation.
