Fizoptika VG091A Fiber Optic Gyroscope ±500°/s 5V UAV Sensor

MFOG-24 Micro-Nano Fiber Optic Gyroscope (hereinafter referred to as “the product”) is a high-precision angular rate sensor designed as a direct replacement for the Fizoptika VG191A. It seamlessly integrates optical, mechanical, and electronic technologies to deliver accurate and reliable angular velocity measurements. Based on the Sagnac effect, the gyroscope detects angular motion by measuring the phase difference between two beams of light traveling in opposite directions within a fiber loop. This phase difference is precisely processed and fed back to achieve high-accuracy angular rate sensing.

Featuring a compact and lightweight design, the MFOG-24 incorporates advanced micro-nano fiber components for enhanced sensitivity and stability. Its internal architecture eliminates moving or wearing parts, ensuring fast start-up, minimal maintenance, and long-term durability. The robust construction and optimized performance make it ideal for attitude control and motion sensing applications, including unmanned aerial vehicles , autonomous navigation systems, robotics, and aerospace platforms. As a replacement for the VG191A, it offers comparable or superior performance while maintaining reliability and precision in demanding environments.

The product is mainly composed of the following components:

• An optical path assembly
• Detection and control signal circuit board
• Optical fiber ring skeleton, shell and other structural parts
