Digital comparative holography is a useful mechanism for checking the body or contortion of two corresponding entities with diverse micro architecture. The spatial light modulator (SLM) is deployed for illuminating the entity with the master entity’s mask; It is also of importance to analyze the edges of the entities by the aid of the SLM. In this paper, primarily we describe the fundamental concepts of digital comparative holography and also we will use SLM for wave front manipulation and explain the results with template matching technique. Template matching is a technique in digital image processing for finding small portions of an image which match a template image to be used as a way to detect edges in images. Here in this carried out research, an approach has been taken to our selected picture in digital comparative holography’s context by applying SLM and template matching notions to detect the edges and explain the details by demonstrating the light and optical behaviors
