摘要：
A multiple wavelength optical system includes plural solid state light sources, an optical diffuser, a lens assembly, and at least one photodetector. The solid state light sources have different wavelength ranges respectively. The optical diffuser has an incident surface and an exit surface opposite to the incident surface. The solid state light sources are disposed opposite the incident surface, and the lens assembly is disposed opposite the exit surface. Each of the solid state light sources faces the incident surface with the same direction. The lights of the solid state light sources enter the optical diffuser and exit from the exit surface, and then are focused by the lens assembly. Finally, the focused lights are projected on a surface of a measured object. At least one photodetector receives the reflected lights or the penetrating lights from the surface of the measured object.本揭露提供一種多波長光學系統,包含多個固態光源、散射板、透鏡組以及至少一光偵測器。固態光源之每一者的波長範圍互不相同。散射板具有入光面及與入光面相對之出光面,其中固態光源與入光面相對設置,且透鏡組與出光面相對設置。固態光源之每一者係以同方向面向入光面出光至散射板後從出光面射出,且經透鏡組聚焦後投射至待測物體表面,並由光偵測器接收來自待測物體表面的反射光或透射光。100‧‧‧多波長光學系統110‧‧‧光源模組112‧‧‧固態光源114‧‧‧散射板114a‧‧‧入光面114b‧‧‧出光面116‧‧‧透鏡組118‧‧‧控制模組120‧‧‧收光模組122‧‧‧光偵測器124‧‧‧訊號處理模組200‧‧‧待測物體210‧‧‧第一位置220‧‧‧第二位置
