Abstract
An optical transformation module includes a light generator generating a parallel light beam to be incident onto a surface of an inspection object and changing a wavelength of the parallel light beam, and a rotating grating positioned on a path of the parallel light beam and rotatable by a predetermined rotation angle such that the parallel light beam is transformed according to the wavelength of the parallel light beam and the rotation angle of the rotating grating to have a desired incidence angle and a desired incidence position onto the surface of the inspection object.
