Scanning-type distance measuring apparatus
A scanning-type distance measuring apparatus includes: an optical system 9 having a first deflecting member 9a that deflects measurement light output from a light transmitting unit 3 toward a space to be measured via an optical window, a light receiving lens 9c that condenses reflection light from an object R to be measured existing in the space to be measured, and a second deflecting member 9b that deflects the reflection light passed through the light receiving lens toward a light receiving unit 5 disposed to oppose the light transmitting unit 3; a scanning mechanism 4 that rotates the optical system 9 about a predetermined axis P; and an optical member 90 that outputs the measurement light deflected by the first deflecting member 9a from an incident light path Lc of the reflection light to the second deflecting member 9b.
