Abstract

Based on the statistical properties of laser speckle, the response for laser speckle passing through a linear shift- invariant system is studied. This paper presents a method for testing the modulation transfer function (MTF) of charge-coupled devices below the Nyquist frequency. A new scattering microcrystalline glass material generates laser speckle. The instrument is designed and test results show that this technique is a variable MTF measurement approach. The difference of the results of each test is within 0.03.
