Latest Patents
Tomasko holds a patent for improvements in fiber optic sensing systems. This patent describes several enhancements, including the incorporation of a dielectric filter applied directly to the sensing end of an optical fiber detector. This filter reflects a reference light beam of one wavelength while allowing a sensing signal of a different wavelength to pass through. The system is designed to be self-compensating, as both light signals are reflected back through the fiber and are attenuated in a similar manner in response to noise sources. The ratio of the intensity of the two signals is proportional to the sensed parameter. Additionally, the dielectric filter is coated onto the fiber's exit end using vapor deposition techniques. The invention also utilizes time division multiplexing to sequentially activate multiple light sources, with a single photodetector measuring the intensity of the reflected signals. Another notable improvement involves the use of an off-axis parabolic mirror for separating input and reflected signals, enhancing separation efficiency.
