Latest Patents

Among his latest innovations, two notable patents stand out:

1. **Fiber optic Sagnac interferometer with spatial filter**

This patent describes a fiber-optic Sagnac interferometer designed specifically for determining rotational speeds, commonly known as a fiber gyro. The system includes an optical directional coupler positioned in the light path from a light source, connecting through a spatial filter and a polarization filter to a beam splitter. This configuration allows for two component light beams to traverse the ends of an optical fiber and return to an interference point, where they are applied to a light-sensitive receiver. A significant advancement of this invention is the integration of a spatial filter made from monomode fiber, which reduces amplitude errors and offers cost savings for the optical directional coupler.

2. **Closed loop fiber optic gyro with Shupe effect compensation**

This patent encompasses a method and device tailored to compensate for Shupe effect drift errors that can occur in fiber gyros due to temperature fluctuations over time. The closed-loop fiber optic gyro incorporates a Voltage-Controlled Oscillator (VCO) control loop along with an evaluation unit designed to account for variations in the optical path length of the light as it passes through the fiber coil. This inventive approach enables effective compensation for temperature-dependent drift changes, thus enhancing the precision of the device.
