Abstract

a invenção descreve um dispositivo de iluminação (100) para iluminar uma disposição tridimensional (250) em um espectro do comprimento de onda infravermelho. o dispositivo de iluminação (100) compreende pelo menos um primeiro grupo de dispositivos a laser (110) que compreende pelo menos um dispositivo a laser (105) e pelo menos um segundo grupo de dispositivos a laser (120) que compreende pelo menos um dispositivo a laser (105). o primeiro e o segundo grupo de dispositivos a laser (110, 120) são adaptados para ser operados de modo independente um do outro. o primeiro grupo de dispositivos a laser (110) é adaptado para emitir luz de laser com uma primeira característica de emissão e o segundo grupo de dispositivos a laser (120) é adaptado para emitir luz de laser com uma segunda característica de emissão diferente da primeira característica de emissão. a invenção descreve adicionalmente um dispositivo de detecção de distância (150) e um sistema de câmera (300) que compreende tal dispositivo de iluminação (100). as diferentes características de emissão podem ser usadas para compensar ou levar em consideração a profundidade da estrutura tridimensional (250). diferentes partes da disposição tridimensional (250) podem ser iluminadas através da primeira e da segunda característica de emissão de diferentes maneiras.
