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
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 = 2RӨ (Since […]
