Latest Patents

Danielson's latest patents include innovations in fiber optic pressure sensors. One of his notable inventions is a fiber optic pressure sensor that incorporates drift correction means for in-situ applications. This invention features an improved intensity-encoded fiber optic sensor that utilizes novel drift correction and filtering techniques. The first embodiment of this invention addresses the removal of unwanted higher-order core and cladding modes from an intensity-encoded signal in an optical fiber. This is achieved through the use of mode strippers and mode filters strategically placed within the sensing system. Additionally, the invention introduces an enhanced technique for long-term temporal drift cancellation. This is accomplished by periodically applying pressure to the sensor tip to determine the measured voltage at which the sensor diaphragm contacts other elements. The measured voltage is then subtracted from an initial calibration voltage, resulting in a constant correction term applied to the measured signal.
