    摘要: A measurement method includes emitting a transmission signal comprising at least one light pulse, wherein an amplitude of an intensity of the light pulse is modulated with a modulation frequency, detecting a receiving signal comprising at least a part of the transmission signal that is reflected from an external object, selecting at least one frequency component of the receiving signal corresponding to the modulation frequency of the transmission signal, and determining a distance to the external object from a time difference between the emission of the transmission signal and the detection of the selected frequency component of the receiving signal.

    摘要: A method for the time-differentiated detection of a spectrum of a test object comprises providing a first conversion dye, which is configured to convert light with a first spectral distribution in the visible range into light with a second spectral distribution in the infrared range. The first conversion dye is excited with a light pulse in the range of the first spectral distribution during a first time period, and a light fraction, reflected or transmitted by the test object, in the range of the first spectral distribution is registered during a first time interval. During a subsequent second time period, a fraction of converted light reflected or transmitted by the test object is registered. According to the invention, the first time interval is selected so that it lies substantially inside a luminescence lifetime for the first conversion dye in the first time period.

    摘要: A light emission arrangement includes a driver arrangement having a first, a second, and a third driver. The light emission arrangement also includes a number N of assemblies. Each assembly includes a first, a second, and a third light-emitting semiconductor body. The number N is greater than 1. The first driver is coupled to a first series connection including the first light-emitting semiconductor bodies of the number N of assemblies. The second driver is coupled to a second series connection including the second light emitting-semiconductor bodies of the number N of assemblies. The third driver is coupled to a third series connection including the third light-emitting semiconductor bodies of the number N of assemblies. The first, second, and third driver are each configured to output a driver signal dependent on photometric quantities of the first, the second, and the third light-emitting semiconductor bodies of the number N of assemblies.
