Device for detecting impression, such as fingerprint on tracking carrier for use in forensic investigation for detecting dactyloscopic impressions, has receiving head with camera, and infra-red emitter provided above drivable emitter holder

摘要

The device has a receiving head (4) with a camera (2), which receives infra-red radiation. An infra-red emitter is provided, which is arranged in the receiving head, such that the infra-red radiation emitted from the infra-red emitter strikes on the impression on the tracking carrier. The infra-red emitter is provided above a drivable emitter holder as a part of the receiving head, which is moved or pivoted corresponding to the infra-red camera. The infra-red emitter is moved around the camera by the drivable emitter holder in a circular arc or circular manner. An independent claim is included for a method for detecting an impression on a tracking carrier.
