A fiber optic gyro measures rotation using the _______ of the two beams?(a) Intensity difference(b) Resonance(c) Interference intensity(d) Wavelength difference |
|
Answer» Right choice is (c) Interference intensity To elaborate: In a fiber optic gyro, The counterpropagating beams are launched into an optical path and are recombined as they exit. The interference generated by the recombination depends on the optical phase difference between the two beams and therefore provides a measure of rotation. |
