A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.
In a rotating ring laser gyroscope, the two counter-propagating waves are slightly shifted in frequency and an interference pattern is observed, which is used to determine the rotational speed. The response to a rotation is a frequency difference between the two beams, which is proportional [ 1 ] to the rotation rate of the ring laser ( Sagnac ...
This is called a ring laser or ring laser gyroscope. The light is generated and sustained by incorporating laser excitation in the path of the light. To understand what happens in a ring laser cavity, it is helpful to discuss the physics of the laser process in a laser setup with continuous generation of light.
A ring laser gyro (RLG) splits a beam of laser light into two beams in opposite directions through narrow tunnels in a closed circular optical path around the perimeter of a triangular block of temperature-stable Cervit glass with reflecting mirrors placed in each corner. When the gyro is rotating at some angular rate, the distance traveled by ...
When the Boeing 757-200 entered service in 1983, it was equipped with the first suitable ring laser gyroscope. This gyroscope took many years to develop, and the experimental models went through many changes before it was deemed ready for production by the engineers and managers of Honeywell and Boeing. It was an outcome of the competition with ...
Illustration of a Semiconductor Ring Laser (SRL). The laser cavity is a waveguide with a racetrack geometry (but this can also be another geometry), which enables it to lase in two counterpropagating directions: clockwise (CW) and counterclockwise (CCW). The light is evanescently coupled out of the cavity to a straight output waveguide.
