Abstract. Three options of photometric wedge formation and employment in digital photometric shadow method are described. The methods allow for building the wave front deformation map and evaluation of image quality characteristics for the optical system under investigation from a pair of digital patterns processed with the use of specially designed software.
Keywords: shadow method, izofotometry, image structure, Foucault knife-edge, photometric wedge, wave front deformation map
