Abstract
An infrared projector and an infrared observation system by which unevenness of wavelengths in a projection pattern is reduced are provided. An infrared projector () is provided with infrared semiconductor laser elements (to) that emit near-infrared laser light beams (L, L, L, and L), a scattering member () that receives and scatters the near-infrared laser light beams, and a projecting member () that projects the near-infrared laser light beams scattered by the scattering member.
