RLG SIGMA 40 is based on Ring Laser Gyroscope technology. RLG is a type of gyroscope based on the principles of interferometry and the Sagnac effect, which is a relativistic phenomenon in the theory of electromagnetic fields. In this article, we learn details about  RLG SIGMA 40, its features, core aim, and the units.

Sagnac effect : The Difference in path Length (∆L) is directional proportional to Angular Rotation (ω). When course is steady:- Path traveled by F1=2πR Path traveled by F2=2πR When Course changes:-     Path traveled by F1= 2πR+AB Path traveled by F2= 2πR - AB Difference in Path Length i.e. ∆L  =  2AB or ∆L =...
