OCR 09WP 11 / 02 / 2569 1. The digital holographic fingerprint analyzer consists of a device housing (19) for Cover all the equipment mounted on the optical equipment mounting table (20), in which area? One side is fitted with a switch (16) connected to a laser (1) which acts as a light source to create an image. When the switch (16) Turn on the operation. The light from the laser (1) travels to strike the first beam splitter (2) to make the light It is split into a first beam (3) and a second beam (4), with the first beam (3) traveling into the device. Expand the beam (7) to reflect it to the mirror (9) and then reflect it into the second beam splitter. (11) and a second beam (4) is reflected into a mirror (6) so that the light travels into the beam extender. The second beam (8) travels through a convex lens (10) to converge the light into a second beam splitter (11). And the light travels and strikes through the objective lens (12) and shines through to strike the fingerprint on the collection device. Fingerprint (13) by the first beam (3) and the second beam (4) return to the point of interference (15). And an image is produced at the camera area (14), where all of the above equipment is mounted on a table for The optical equipment (20) is installed, and the camera (14) takes a picture of the fingerprint and sends the image. The fingerprint is transmitted via a data cable (17) connected from the camera (14) to the computer (18) by Computer (18) performs the function of taking the obtained image data and analyzing whether the fingerprints are likely to be Whether it's cancer or not, this will be compared to a dataset of cancer patients and healthy individuals trained by the system.
