With high demand in performances, ring laser is proposed as an angular measuring transducer, due to its many considerable advantages compared to other means of angle’s measurement, since it’s based on the physical fundamentals, methods, equation/logarithms are developed and experimental work using high precision goniometer, this paper focus on reducing the instability, zero shift, the resolving power to as low as 0.05, the technique required to determine the output frequency within angle of periods in the RL output signals in an entire rotation (2π), The output characteristics instability of scale factor (K1) and zero shift (Ko ) was observed with time and the effect of instability on the rotational velocity of RL in regard to component error in measurement was minimized, the type of RL used proved to be the square type as different values based on CW and CCW was recorded.
