Fizoptika is a leading developer of state-of-the-art ultra-miniature FOG (fiber optic gyroscope) technologies for UAVs (unmanned aerial vehicles), drones and robotics.

Miniature FOG Gyros for UAVs

Our high-accuracy FOG sensors provide precision motion and orientation measurement in rugged, lightweight packages.

Based on 40-micron polarization maintaining (PM) fibers, our UAV gyros are constructed using a sophisticated spliceless technology that fabricates the entire fiber optic assembly from a single fiber length. This jointless construction results in zero excess optical loss.

We pride ourselves on the reliability and superior quality of our designs and products, and all Fizoptika fiber optic gyros are UNI EN ISO 9001:2015 certified.

Our fiber optic gyros offer a variety of advantages for UAV and unmanned systems applications:

  • Fine-tuned assembly provides immunity to electromagnetic interference, eliminating the need for heavy shielding
  • Bias immunity to vibration and gravitational acceleration
  • No dead zones or hysteresis
  • Effectively instant response
  • No cross-axis sensitivity error.

VG1703 Series Fiber Optic Gyroscopes

Ultra-compact, lightweight UAV FOG sensors

VG1703 fiber optic gyro sensorsThe VG1703 series of FOG sensors features excellent bias and angle random walk in an extremely compact package that is ideal for SWaP (size, weight and power)-constrained UAVs and unmanned systems. With a durable aluminium and hard plastic construction, the gyros can withstand 1200g shocks, and exhibit a 15-year mean time before failure (MTBF).

The high-quality single mode fiber minimises optical loss and maintains optical guiding ability even under high degrees of elastic and plastic deformation. Precision fusion-tapering and soldering processes provide highly mechanically stable and temperature-stable components, with stringent test procedures maintaining quality at all stages of manufacture.
