1 January 1993 Measurement equipment for CAQ-based final control of optical systems
Author Affiliations +
Measurement equipment is presented for the quick measurement of modulation transfer function (MTF), image field curvature (FC), and chromatic aberration (CA) of optical systems. The measurement device is based on a cooled CCD-matrix element as image analyzer and on a set of pinholes as objects. It is intended to be used in final quality control of optical systems and is thus incorporated into a system of computer aided quality assurance (CAQ) which has been developed in the last few years. After a description of the hardware modules and the interface constellation to the computer hardware (for the various control and regulation systems), the structure of the associated software and the function within the CAQ-System is described. An example of the test procedure for a fixed focal length optical system is given.
