Abstract
The present invention relates to a distance measurement apparatus. The distance measurement apparatus according to the present invention has, mounted thereon, a light transmitting portion which emits light, and a light receiving portion including a light receiving element where a spot of the light is collimated. The present invention comprises: a tilting base; and a rotating reflector which reflects the light emitted by the light transmitting portion to an object, and reflects the light reflected or scattered by the object to the light receiving portion.
Claims16
An apparatus for measuring a distance, the apparatus comprising:
- a base mounted with a light transmitter emitting light and a light receiver receiving light;
- and
- a rotatable reflector reflecting light emitted from the light transmitter to an object and reflecting light reflected or dispersed from the object to the light receiver,
- wherein the base is tiltable from a first position to a second position different from the first position,
- wherein the light transmitter emits light in a first direction when the base is in the first position and the light transmitter emits light in a second direction different from the first direction when the base is in the first position,
- wherein the light receiver receives light in a third direction when the base is in the first position and the light receiver receives light in a fourth direction when the base is in the second position, and
- wherein a pathway of light reflected from the reflector is changed according to rotation of the reflector.
