Abstract

The present disclosure relates to a device 1000 for contactless acquisition of biometric data from skin areas. For example, a sensor optics arrangement 120 of the image acquisition unit 100 or an emitter optics arrangement 220 of the illumination unit 200 is offset such that the focal planes 135, 235 of the image acquisition unit 100 and the illumination unit 200 essentially completely overlap. As a result, for example, the area of the optical sensor 115 of the image acquisition unit 100 or the area of the light emitter 215 of the illumination unit 200 can be used to the maximum, thereby resulting in a significantly improved quality of the acquisition of the biometric features of a hand, in particular the fingers. In addition, the compactness of the device 1000 can be further increased, for example by beam folding using reflective optical elements 700.

Dependent claims

Device for contactless acquisition of biometric data from skin areas, comprising:

at least one image acquisition unit, which comprises an optical sensor and a sensor optics arrangement arranged upstream in the beam path and is configured for contactless acquisition of image data from illuminated skin areas, and
at least one illumination unit, which comprises a light emitter and an emitter optics arrangement arranged downstream in the beam path and is configured to illuminate the skin areas to be acquired by the image acquisition unit,
wherein the sensor optics arrangement is arranged offset relative to the optical sensor along the optical main planes of the sensor optics arrangement or the emitter optics arrangement is arranged offset relative to the light emitter along the optical main planes of the emitter optics arrangement, so that the focal plane section of the image acquisition unit and the focal plane section of the illumination unit have the greatest possible overlap with one another.

Dependencies are inferred from the claim text.
