Laser Gyroscope

As the professional manufacturer, we would like to provide you Laser Gyroscope. The principle of the laser gyroscope is to measure the rotational angular velocity ( Sagnac effect) by using the optical range difference. In a closed optical path, two beams of light transmitted in clockwise and anti-clockwise directions from the same light source and optical interference, using the detection of phase difference or interference fringe changes, you can measure the closed optical path rotational angular velocity. The basic element of the laser gyroscope is the ring laser, the ring laser by a triangle or square quartz made of closed optical circuit composed of one or more tubes containing a mixture of gases (helium-neon gas), two opaque mirrors and a semi-transparent mirror. The gas mixture is excited with a high-frequency power supply or a direct-current power supply to produce a monochromatic laser. In order to maintain the resonance of the loop, the circumference of the loop should be an integer multiple of the wavelength of the light wave. The translucent mirror is used to direct the laser light out of the loop, and the mirror causes the two oppositely transmitted laser beams to interfere, and a digital signal proportional to the angle of the output is fed through the photodetector and circuit.
