SOLID STATE OR LASER GYROS

1
The ring laser gyro (RLG) IS JUST ABOUT AS DIFFERENT FROM A CONVENTIONAL GYRO AS IT POSSIBLE TO GET .THE rlg OPERATES ON THE PRINCIPLE of the relativemovement of two beams of laser light, whereas a conventional gyro operates on the principla of stored mechanical energy (inertial). RLGs are a solid state alternative to the conventionalrate integrating gyro.
CONSTRUCTION
2
THE CONSTRUCTION of a triangular ring laser gyro is shown at figure 13.1 shows a cross section through the sensitive plane of the RLG ,thesensitive axis passes perpendicularly through the page . square RLG are also manufactured ,the principle of operation is much the same.
3
the RLG is formed from a solid block of cer vit(glass/ceramic ) material which is used because it has a very ñow temperatura co- efficient . it does not distort with age , which would degrade the accuracy and perhaps destroythe gas right seal necessary to contain the helium and neon gases .
Channels are drilled very accurately in the block to from two triangular laser paths which are filled witha low pressure helium /neon mixture.
4
Two anodes and a common cathode are used to created electrical discharges within the gases which cause the channels to act as gain tubesproducing laser beams . these beams travel in opposite directions around the triangular block.

5
At each of the three corners of the block are flat mirrors which reflect thelaser beams into the next channel .two of these mirrors (B and C at figure 13-1 ) are mavable and are controlled by piezo electric actuators operating in a closed loop system toadjust the optical path length to within precise limits, and so to correct for the small expansións/contractions of the block with changing temperatures within the permitted...
