Abstract
The measurement device includes a light source that emits the distance measurement light, a focusing member that transmits the reflected distance measurement light and reflects reflected collimated light to form an image of the measurement target object, the reflected collimated light being reflected by the measurement target object and in a wavelength band different from a wavelength band of the reflected distance measurement light, a distance measurement light reception unit that receives the reflected distance measurement light that has been transmitted through the focusing member and the internal reference light, and a collimated light reception unit that receives the reflected collimated light reflected by the focusing member.
