摘要： A method for operating a laser light source including the steps: a) cyclically ascertaining an electrical voltage drop at the laser light source by energizing the laser light source; b) cyclically ascertaining a temperature of the laser light source from the ascertained electrical voltage drop with the aid of a first mathematical connection previously ascertained from the electrical voltage and the temperature of the laser light source; c) ascertaining a current which causes an essentially constant visual output of the laser light source for each ascertained temperature value with the aid of a second mathematical connection from the visual output and the current; and d) energizing the laser light source using this current.

摘要： A projector having at least one laser diode which is designed to emit light, having a laser control device which is designed to control the at least one laser diode, having a first controllable resonant mirror which is designed to reflect the light that is emitted by the laser diode, and having a control device which is designed to control the orientation of the first controllable resonant mirror. The control device is further designed to reduce the power supply to the laser diode and to the laser control device in a first configuration of a power-saving mode of the projector, and to further control the orientation of the first controllable resonant mirror at a resonant frequency of the first controllable resonant mirror. Moreover, a corresponding method is described.

摘要： A method for ascertaining a gesture performed in the light cone of a projected image which has a plurality of pixels includes: detecting all pixels of the projected image and one or multiple parameter values of the individual pixels; comparing the one or the multiple detected parameter values of the individual pixels with a parameter comparison value; assigning a subset of the pixels to a pixel set as a function of the results of the comparison; and ascertaining a gesture performed in the light cone of the projected image based on the assigned pixel set.

摘要： The invention relates to optical arrangements which can be provided, preferably also in miniaturized form, for the most varied applications. They can be used in many sectors of life and also commercially, and indeed whenever information should be presented visually and/or optical information should be recognized and taken into account. It is the object of the invention to provide optical arrangements with which different optical information can be utilized in more complex form together in one arrangement. The optical arrangement in accordance with the invention is configured such that elements both emitting and detecting electromagnetic radiation are arranged on a common substrate or are configured thereat. A plurality of these elements are preferably present together in each case. It can, however, also be sufficient for specific applications to provide in each case an emitting or a detecting element with a plurality of the respective other elements.
