Sensor for spectral analyzer for living tissues
First Claim
Patent Images
1. A sensor for a spectral analyzer for living tissues comprising;
- a holder, a bundle of fibers held in position in said holder and connected to the analyzer, a probe including a reflector fitted to an end thereof, said probe being axially movable by a predetermined distance with respect to said holder, a light transmitting/receiving fiber connected to a switch circuit of said analyzer, and a spring positioned between said holder and said probe for urging said reflector away from a tip of the light transmitting/receiving fiber, said switch being actuated so as to be turned on in response to a decrease in the intensity of the light reflected into said fiber due to a decrease in a distance between said tip of the light transmitting/receiving fiber and said reflector.

Abstract
A sensor for a spectral analyzer includes a relatively movable holder and probe, where the probe is fitted with a reflector, and the holder is provided with a pair of adjacent optical fibers for transmitting/receiving light. When the probe abuts the surface of the object to be measured, the probe and holder move relatively so that the fiber pair approach the reflector. A switch activating the analyzer for data collection is operated in response to the change in reflected light intensity caused by the relative movement.
