摘要： A projection system for a vehicle, in particular for an ambient lighting device for generating a plurality of light cones for illuminating the ground in the surroundings of the vehicle, includes at least one light source and a microlens array. The microlens array includes an optical axis, a first portion with at least one first channel and a second portion with at least one second channel. The projection system includes an optical device that is provided downstream of the microlens array and is arranged at least in the area of the first portion, with the distance between the microlens array and the optical device being less than 20 mm. Light emitted by the light source, which falls through the at least one first channel of the first portion, is deflected by the optical device by a first angle with respect to the optical axis and forms a first light cone, and light emitted by the light source, which falls through the at least one second channel of the second portion, is deflected by a second angle with respect to the optical axis, which differs from the first angle, and forms a second light cone.

摘要： An exemplary micro-optical component includes a micro-substrate and a micro-optical element disposed on the micro-substrate. The micro-optical element is structured to modify or process light. At least a portion of a component tether is physically attached to the micro-substrate or physically attached to the micro-optical element. The micro-optical component has a thickness less than 250 μm. Light can be processed by reflection, refraction, diffraction, frequency changes, polarization changes, color-temperature or frequency distribution changes, or phase changes. The micro-optical component can be disposed on a system substrate to form a micro-optical system. The system substrate can include a cavity and the micro-optical element can be disposed at least partially in the cavity. Micro-optical components can be passive optical micro-devices. A light-active element can be disposed on the micro-substrate to receive light from or emit light to the micro-optical element.

摘要： A micro-lens based module including at least one nanostructured layer, the nanostructured layer including one or several diffractive domains corresponding to an optical object. The claimed micro-lens based module allows dynamic and/or coloured projections of optical objects with an improved optical quality. The present invention also relates to a projection device and a method of projection of improved coloured and/or dynamic images.

摘要： A method for assessing the quality of a multi-channel micro- and/or subwavelength-optical projection unit is disclosed. The method comprises the following steps: At least a predefined portion of the optical projection unit is illuminated so that an image is generated by at least two channels of the predefined portion of the multi-channel optical projection unit. At least one characteristic quantity is determined based on the analysis of the image, wherein a value of the characteristic quantity is associated with a characteristic feature of the projection unit, a defect of the projection unit and/or a defect class of the projection unit. The quality of the projection unit is assessed based on the at least one characteristic quantity. Moreover, a test system for assessing the quality of a multi-channel micro- and/or subwavelength-optical projection unit and a computer program are disclosed.
