This paper presents a non-contact optical system for real-time gyroscope drift measurement under simulated spin-stabilized missile conditions, integrating the laser reflection principle with webcam-based image processing. The gyroscope was mounted on a flange coupled to a servo-motor shaft rotating continuously at 10 Hz to replicate representative missile spin dynamics, with electrical continuity maintained through a multi-channel slip ring. The proposed system demonstrates that gyroscope drift can be reliably measured in a continuously rotating environment using only low-cost, commercially available hardware, providing a practical solution for inertial sensor calibration and performance evaluation in guidance research on spin-stabilized missiles.
