AI Technical Summary

Technical Problem

Existing non-contact biometric data acquisition systems face challenges in maintaining a compact structure while ensuring high-quality fingerprint acquisition, often resulting in image distortion due to overlapping depth of field of the camera and projector.

Method used

The proposed solution involves offsetting the sensor optical arrangement with respect to the optical sensor and/or the emitter optical arrangement with respect to the light emitting element, allowing for maximum overlap of the focal plane sections of the image acquisition unit and the illumination unit, thereby eliminating image distortion.

Benefits of technology

This approach enables a more compact apparatus with significantly improved image quality and data quality of acquired biometric data, allowing for efficient non-contact acquisition of biometric features with high detail and accuracy.

Abstract

The present disclosure relates to an apparatus 1000 for non-contact acquisition of biometric data from a skin area. For example, the sensor optical arrangement 120 of the image acquisition unit 100 or the emitter optical 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 basically completely overlap. As a result, for example, the areas of the optical sensor 115 of the image acquisition unit 100 or the light emitting elements 215 of the illumination unit 200 can be used to the maximum extent, and as a result, the quality of acquisition of biometric features of the hand, particularly the finger, is considerably improved. Further, for example, by beam bending using the reflective optical element 700, the compactness of the apparatus 1000 can be further increased.
