In the present forensic era Document Examiners play a very important role in investigating a scene of crime. This division deals with the examination to all types of Questioned Documents, whether it is hand-written or a printed matter, Document Examination is a branch of forensic science which works with help of advanced Technology and instrumentation. The adminicle things to the document examiner are Magnifiers and Microscopes, make small things visible and measurable, combining those devices with cameras allow examiners to get a clear view of the images for proper examination and to present the fact before clients and a flair fact in court of law. To give opinion in matters like establishing genuineness of questioned writings and signatures, identifying or making model or age of type writer, examinations and identification of rubber stamps and metal seals, deciphering erased, altered, added or obliterated writing, indented, charred as secret core tings, traced document and the detection of non-contemporaneous handwritten entries. Examination of writing material like paper, peer, pencil and inks. Dictation of fared lottery tickets, railway tickets, and counterfeit currency notes etc. determination of age of ink, paper and other documents. A variety of other advanced light sources are now available in the modern forensic science to help the examiner for their use where the magnifiers and microscopes are not able to. More recently an instrument known as an Electrostatic Detection Apparatus, or ESDA, is now used to produce a visual image of the indented writing on transparency film. In this method, indented writings are identified and deciphered by means of low angle oblique light and photography. It's a non-destructive and rather non-detectable method. Another instrument such as a Video Spectral Comparator (VSC) assist in the case of an obliteration or alteration. The VSC allows the examiner to examine the document through infrared illumination using as infrared sensitive CCD camera as a detector. The image is examined by viewing on a monitor and digital image processing through a computer. This technique is also very useful in ink differentiation.
