Abstract: The present invention relates to a module for optically exciting a sample volume by means of an optical chip, comprising a control unit, a holding device for an optical chip, at least one coupling unit for guiding light into the optical chip, a positioning unit designed to position the coupling unit or at least parts thereof relative to the optical chip, and at least one detection unit for capturing light from at least one thin-film waveguide of the optical chip, a signal concerning the light captured by the detection unit, in particular concerning the intensity of said light, being transmitted to the control unit, which is designed to control the at least one light source and/or the positioning unit on the basis of the signal.

Abstract: An iris scanning device that includes a single camera sensor utilized for generating iris scan data is described herein. The iris scanning device includes a selector, a lens, and the camera sensor. The selector is configured to receive a first optical signal representative of a first eye and a second optical signal representative of a second eye. The selector selectively allows a passed optical signal to be optically propagated to the lens and inhibits a blocked optical signal from being optically propagated to the lens during a time period. The passed optical signal is one of the first optical signal or the second optical signal during the time period. The blocked optical signal is a differing one of the first optical signal or the second optical signal during the time period. The lens causes the passed optical signal to be incident on the camera sensor during the time period.

Abstract: The present invention relates to an optoelectronic chip for receiving a sample for optical examination, having a carrier layer, a thin-film lightguide having an active region, in which the sample interacts with a guided mode of the thin-film lightguide, wherein at least one scattering structure is arranged in the active region, which scatters a part of the light guided in the thin-film lightguide, whereby a reference light field is produced. The invention further relates to an optical system having such a chip. The system is used for the marker-free analysis of particles, particularly biomolecules in their natural environment.

Abstract: The present invention relates to an optoelectronic chip for receiving a sample in the visualization of temperature-dependent processes, having a carrier layer, a thin-film lightguide and a thin-film heating element, wherein the thin-film lightguide and the thin-film heating element are preferably arranged on sides of the carrier layer that lie opposite each other.
