FIELD: optical engineering.
SUBSTANCE: optical image is formed by means of computer technology; it can be also used for building dactyloscopic maps used by law and order organs. Device has radiation source connected in series and optically related with prism having input, output and papillary pattern perceiving system of photo-receiving members electrically connected with image processing unit. Elastic optical-transparent material is placed onto receiving surface of prism. Material can move relatively receiving surface of prism. Space between elastic optically-transparent material and prism is filled with immersion liquid.
EFFECT: improved quality of images registered by photoreceiver.
