Sensing system with a multi-channel fiber optic bundle sensitive probe
First Claim
1. In a sensing system for simultaneously sensing at least one parameter from the group consisting of displacement, roughness and two angles between a probe tip and a light reflected target, including a fiber optic light conducting bundle having light transmitting fibers and light receiving fibers, wherein the improvement comprises:
- a multichannel fiber optic bundle sensitive probe having a flat sensitive probe tip end with at least three types of transmitting and receiving ends of channels divided between three branches;
a) a first of said three branches consisting essentially of receiving fibers directed to four sections, means for symmetrically orienting the fibers within a middle point of each section, means for connecting the fibers optically with four respective light sensors;
b) a second of said three branches consisting essentially of receiving fibers collected into two sections, means for symmetrically orienting the receiving fibers around the receiving fibers of said first branch, means for connecting the fibers with two respective light sensors; and
c) a third of said three branches consisting essentially of transmitting fibers symmetrically oriented and collected in at least five separated transmitting sections and connected with between one to five light sources.

Abstract
A sensing system with a multichannel fiber optic bundle (MFOB) sensitive probe for measuring displacement, vibrations, roughness and two angles between a probe tip and light reflected target. The MFOB sensitive probe includes three branches of transmitting and receiving channels. The tip end of the MFOB is arranged in a rectangular 3*3 matrix formation. The other end of the MFOB includes eleven optical tips and connectors for optically connecting the tip of each channel, through optical filters, with light sensors and light sources. The sensing system further includes an electronic portion, having a thermostabilized box, an analog portion of an electronic module, a multifunction input/output board for use with a computer, and a controller for programmably controlling and measuring all parameters using computer analysis.
