Digital Closed Loop Single Axis Fibre Optic BW-700A
BW-700A Digital Closed Loop Single Axis Fibre Optic BW-700A Product Introduction:

●All-fiber optics technology: Angular velocity sensor with long life, small size, high stability and anti-interference
●Intelli-Process Technology:Built-in high-performance digital signal processing chip to realize all-digital working mode. Adaptive filtering technology reduces the zero drift and angular velocity random walk of the gyro by 50%-75% compared to similar products
●Integrated optical fiber polarization technology: reduce insertion loss, improve extinction ratio, and provide better resistance for temperature, mechanical shock and vibration for the optical path
●Compact and highly stable package: adapt to various harsh environments, widely used in various civil and military occasions
●Quick Launch technology:Realize instant start of gyroscope without external calibration
●Optimal working wavelength: Under the same structure, size, and cost, the sensitivity can be increased by nearly 50%
●Noise isolation and compression technology: significantly reduce angular velocity random walk
●Self Track and Self-phase tracking technology: improve the dynamic range of the gyroscope
