Scanning Integrator for Producing Sinusoidal Test Objects

Not Accessible

Your library or personal account may give you access

Abstract

An account is given of a simple system for producing a sinusoidal exposure distribution in time and space. A “scanning integrator” is used to scan square-topped periodic test objects, thereby presenting the desired exposure distribution to the lens system under test. The effects of various geometrical shapes of the entrance aperture of the scanning integrator on the exposure distribution are investigated. By such a direct scan, sine waves of opacity result on the recording film, which may then be employed for producing sinusoidal transmittance waves by a printing method. Direct sine waves of transmittance are also produced using a nonuniform Ronchi ruling. The simple setup used for this investigation is described, and the microdensitometer traces show that high quality sine wave test objects are obtainable.
