The Optical Mark Reader
The Optical Mark Reader is a device the "reads" pencil marks on NCS compatible scan forms such as surveys or test answer forms. Here is an example of an NCS form... The computer test forms designed for the OMR are known as NCS compatible scan forms. Tests and surveys completed on these forms are read in by the scanner, checked, and the results are saved to a file. Many traditional OMR devices work with a dedicated scanner device that shines a beam of light onto the form paper. The contrasting reflectivity at positions on a page is then used to detect the marked areas because they reflect less light than the blank areas of the paper.
