1.	On the bases of application of optic fiber sensor, which of the following is not considered to be the classification of fiber optic sensor?(a) biomedical/photometricsensors(b) physical sensors(c) thermal sensors(d) chemical sensorsI got this question by my school teacher while I was bunking the class.This question is from Optical Fiber Sensors in portion Physiological Transducers of Biomedical Instrumentation
Answer» Correct choice is (C) THERMAL SENSORS Explanation: The variations in the returning light are sensed using a photodetector. Such sensors monitor variations EITHER in the amplitude or frequency of the reflected light. Two of the most important PHYSICAL parameters that can be advantageously measured using fibre optics are temperature and pressure.
