Abstract
PURPOSE: To realize a measurement of distance to a target object, by providing the light source at the vertex (original point) of the light emitting barrels forming two sides of a triangle along with installation of a reflector at the tip of one light emitting barrel and then giving a control so that the light beams emitted from the light source are cross on the target object and then both the original point and the target object may be a focus of the oval passing through the center of the reflector.
CONSTITUTION: The light emitting barrels 4 and 5 are provided to form two sides of a triangle, and the light source 3 is provided to the vertex A. At the same time, the rotatable reflector 2 is installed at the tip of one barrel 5 with a certain distance secured from the light source. Then a control is given so that the beams from the light source 3 are cross to each other on the target object 1 and both the object 1 and the light source 3 may be the focus of the oval passing through the center 2 of the reflector. The length of the sides of the triangle 231 is set as (a), (b) and (c) each from 2 toward 3; and the angle formed with the side (a) and the face of the reflector is set δ along with the angle 231 [opposite angle of side (c)] set to θ1. The opposite angle of the side (b) is obtained as θ2=π-2δ by measuring the length of the side (a) plus the angles δ and θ1. Accordingly, the opposite angle θ3 of the side (a) can also be known, and as a result the distance (b) to the target 1 can be known.
