Abstract
PURPOSE: To simplify constitution and reduce size and weight by measuring the outside diameter size of the measuring object from the photodetecting output of photodetectors.
CONSTITUTION: Light from a light emitting source 1 is radiated as the parallel light of a diameter larger than the outside diameter D of the measuring object 3 by a lens 2 to the object 3 in its perpendicular direction. The outside diameter image (d) obtained by this radiation light is imaged on the light incident plane of a photoconductive band 4. Thence, according to this outside diameter image (d), the light input propagates in the photoconductive band 4 and is detected in respective photodetectors 7. The detection outputs thereof are analyzed to measure the outside diameter size D of the measuring object 3. Here, the photoconductive band 4 is made by flatly and regularly arraying a multiplicity of optical fibers 5, forming them in strip form by means of flexible resin or the like and constituting the light incident plane 6 in linear form.
