Title: Limited reflection type sensor
Inventor: UNO TETSUYA
IPC: G01J1/06
Filed: 1991-07-19
Abstract: PURPOSE:To enable detection of an object within a limited long-distance range by providing a light-intercepting plate which covers a part of a light-sensing element sensing a reflected light from the object being present in a limited reflection region. CONSTITUTION:A light-sensible region R is limited to be narrow by providing a light-intercepting plate 10 covering a part of a light-sensing element 12. A mark P shows the right end of the region R in the case when the light- intercepting plate 10 is not provided. In other words, a scattered light in a region shown by a mark N is obstructed by the light-intercepting plate 10 and does not enter the light-sensing element 12. The fore end of the light-intercepting plate 10 is sharpened to be thin so as to eliminate the effect of the thickness thereof. The light-intercepting plate 10 is disposed preferably at a position where a reflected light from an object is imaged on the front of the light-sensing element 12 by a light-sensing lens 8. Thereby it can be avoided that the quantity of light sensed by the light-plate 10. The region R can be limited more by covering the opposite sides of the light-sensing element 12 with two light- intercepting plates. Consequently, a limited reflection region L is limited more as well and only an object inside the more limited region can be detected.

The image pickup signal of the element 11 is inputted to a computer 10 through a cable 12. When the laser light is projected, the laser light is not reflected from the part corresponding to a nonirradiated part around the step D1 and, as a result, a gap is formed at part of the light receiving surface of the element 11.  The computer 10 measures the size of the gap based on the image pickup signal and calculates the thickness of the film 3 from the size of the gap.
