Abstract: A hand-held device for recording of living skin areas of human autopods and documents is disclosed. The device has an image acquisition module with a support surface and a holding unit for a display and an operating module. The holding unit contains a base frame and a folding frame, which are pivotably connected by a mechanical pivot joint. The image acquisition module is arranged in the base frame, with the support surface facing the folding frame, and the display and operating module can be arranged in the folding frame, with the display facing away from the base frame. In an opened state of the holding unit, the base frame and the folding frame enclose an angle of less than 90° and greater than 20° with each other. In a closed state of the holding unit, the image acquisition module can be covered by the display and operating module.

Abstract: A device and method for non-contact optical imaging of a selected surface area of a user's hand, wherein the surface area is actively guided in a non-contact manner into a target position with respect to an image capture unit. For this purpose, the device has a frame in which the hand is inserted, assuming an actual position, roughly related to the target position. In addition, the device contains at least one active means for localizing the respective actual position and an output unit via which feedback is given to the user and the user iteratively guides the surface area into the target position. Advantageously, the device and method are suitable for distinguishing a natural hand from an artificial hand.

Abstract: A device for displaying information and for the contact-based, simultaneous capture of impressions of a plurality of blood-perfused skin regions of human autopodia, including: a placement surface for placing the autopodia, a display unit which is arranged below the placement surface and which has at least partially transparent display elements which are arranged in grid form and are individually controllable by a control unit, the display elements having display pixels which emit light in a direction of the placement surface. The device also includes optical sensor pixels which detect light incident on the sensor pixels. The sensor pixels may be arranged in a sensor layer arranged under the display unit viewed from direction of the contacting skin region or may be arranged in the display unit between the display elements. A cavity filter for angle selection is arranged in front of the optical sensor pixels.

Abstract: An apparatus for direct optical recording of security-related objects with a series of layers comprising a cover layer with an object placement surface, a sensor layer, a spacer layer with spacer structures for limiting light incident from the placement surface to small incident angles on the sensor layer, and a substrate as carrier of the series of layers. To capture security-related objects with good contrast over a large surface, the sensor pixels have a light-sensitive element and a passage region, and the spacer layer is produced by spacer structures provided on the sensor layer or by spacer structures formed from existing raised-shaped function elements, and the spacer layer comprises cutouts in the region of the entrance aperture of every light-sensitive element, each cutout filled with a medium having a refractive index lower than that of the sensor layer and a layer adjoining in a direction of the placement surface.

Abstract: A handheld device contains a main body and a sensor disposed on the main body, which is configured to sense biometric data of a person. A recess formed in the main body is disposed relative to the sensor such that an electronic device with a light means is temporarily receivable in the recess and positionable in the recess below the sensor.
