Abstract: A holographic optics module having a main body having a first surface, and two or more area elements each having a holographic structure is provided, wherein the two or more area elements are arranged on the first surface of the main body such that they form a coherent area that provides a predetermined optical function.

Abstract: A system for a functionalized pane in a door, through which person-based and/or object-based authorization verification can be carried out is provided. The person-based verification can include a holography-based, stereoscopic holocamera that can be integrated into the pane. In addition, a holographic display that can also be integrated into the pane can be included. Corresponding methods can be used to carry out the authorization verification under the control of the control device and to control a locking mechanism of a door and a holographic display.

Abstract: A device for measuring a time of flight of a measuring light beam, comprising a measuring light source for emitting the beam, a light sensor for detecting the beam, a waveguide, and a data processing device. The waveguide is designed to guide the beam emitted by the measuring light source to an object situated in an object region of the device and the beam reflected off the object to the light sensor at least partially through the waveguide, wherein the waveguide includes a measuring diffraction structure for wavelength-dependent deflection of the beam and wherein the beam traverses a wavelength-dependent path length in the waveguide. The data processing device is configured to determine, when measuring the time of flight, an optical path length contribution and/or a time-of-flight contribution for the beam detected by the light sensor, taking into account the wavelength-dependent path length of the beam within the waveguide.
