Stereoscopic examination with low and high power objective is used to detect retouching, patching and unnatural pen lift in signature analysis. With proper angle intensity of illumination, it aids in the decipherment of erasures, some minutes manipulation not perfectly pictured to the unaided eye, and the sequence of entries done by different writing instrument

presence of erasures, matching of serrationand some other typesof alteration
