Abstract: The use of double grating diffraction shearing for measurement of MTF is demonstrated.By superimposing two gratings optically we avoid the problem of grating contact and subsequent degradation.This simple and economical method is especially advantageous for optical systems with large pupil for which a rotating plate interferometer becomes prohibitively expensive.© 1979 Optical Society of America.
