Object tracking and / or object detection device and object tracking and / or object detection method

Abstract

The invention relates to an object tracking and / or object recognition device (60a-d) for at least non-contact detection of relative changes in position and / or velocities of an object (10a-d) and / or non-contact differentiation of differently shaped objects (10a-d), with a laser feedback interferometry (LFI) sensor unit (12a-d). It is proposed that the LFI sensor unit (12a-d) comprises at least one surface emitter (VCSEL) (14a-d) with at least one integrated photodiode (ViP) (16a-d), which forms a plurality of integrated mesas (18a-b, 20b, 22a-d), each of which represents a sensor laser beam source.
