摘要： The present disclosure relates to various embodiments of an optical package for a LIDAR sensor system having a substrate including an array of a plurality of capacitors formed in the substrate, a plurality of switches formed in the substrate, where each switch is connected between at least one laser diode and at least one capacitor of the plurality of capacitors; and at least one laser diode being mounted in close proximity to the plurality of capacitors on the substrate in order to provide small parasitic inductances and capacitances. A processor is configured to control the plurality of switches to control a first current flow to charge the plurality of capacitors, wherein the processor is configured to control the plurality of switches to control a second current flow to drive the at least one laser diode with current discharged from at least one capacitor of the plurality of capacitors.

摘要： A lighting apparatus may include a light generating device for generating a primary light beam, a phosphor body that can be irradiated by means of the primary light beam and serves for partly converting primary light of the primary light beam into secondary light, and a spectral filter disposed downstream of the phosphor body. The spectral filter may be more highly transmissive to the secondary light than to the primary light where the spectral filter is arranged along a beam axis of the primary light beam incident on the phosphor body. The lighting apparatus may be used in LARP arrangement for vehicle lighting, general lighting, exterior lighting, stage lighting, effect lighting, etc.

摘要： Various embodiments may relate to a lighting device including at least two light sources, the light from which has different spectra and is combined to form useful light. For measuring the portions of the light from the individual light sources, part of the useful light, the measurement light, is branched off with the aid of a coupling-out element at the output of the lighting device and is fed to a measuring device.

摘要： The present disclosure relates to various embodiments of an optical component for a LIDAR Sensor System. The optical component includes a first photo diode implementing a LIDAR sensor pixel in a first semiconductor structure and configured to absorb received light in a first wavelength region, a second photo diode implementing a camera sensor pixel in a second semiconductor structure over the first semiconductor structure and configured to absorb received light in a second wavelength region, and an interconnect layer (e.g. arranged between the first semiconductor structure and the second semiconductor structure) including an electrically conductive structure configured to electrically contact the second photo diode. The received light of the second wavelength region has a shorter wavelength than the received light of the first wavelength region.
