| 摘要 |
The invention relates to a multi-channel light source (1) having channels that can be individually modulated for imaging, comprising: a pump radiation source (2) for emitting pump radiation; a luminescent element (3) having a luminescent material for at least partially converting the pump radiation into converted light; a first (12) and a second spatial light modulator (13) for imaging; and a beam splitter (8) that is arranged downstream of the luminescent element (3) in such a way that a useful light, at least partially containing the converted light, falls on the beam splitter (8), wherein the useful light has a first spectral component in a first spectral range and a second spectral component in a different second spectral range, and the beam splitter (8) is transmissive in only one of the two spectral ranges, and reflective in the other, such that the useful light is distributed downstream of the beam splitter (8) onto a first beam path (10) with the first spectral component, and onto a second beam path (11) with the second spectral component, wherein the first spatial light modulator (12) is arranged in the first beam path (10) as the first channel, and the second spatial light modulator (13) is arranged in the second beam path (11) as the second channel, such that a number of channels are provided on the basis of the useful light. |
