Frequently Asked Questions
What is a fiber optic gyroscope?
A fiber optic gyroscope (FOG) is a high-precision angular rate sensor based on the Sagnac effect. It measures rotation by detecting the phase difference between two beams of light traveling in opposite directions inside a fiber coil. FOG sensors are widely used in inertial navigation systems, UAVs, robotics, and stabilization platforms.
Can MFOG-910 replace the VG910H1 fiber optic gyroscope?
Yes. The MFOG-910 micro-nano fiber optic gyroscope is designed to provide comparable performance to the VG910H1. It features similar angular rate range, bandwidth, size, and environmental specifications, making it suitable as a replacement in many inertial navigation and stabilization systems.
