Passive optical wavelength analyzer with a passive nonuniform optical grating |
摘要 |
An optical sensor grating in a fiber-optic experiences a measurable parameter, such as strain, pressure and/or temperature. A passive nonuniform optical grating receives a light signal reflected by the optical sensor grating and spread out by a lens. A photodiode array behind the passive nonuniform optical grating senses a light intensity distribution of the reflected light signal. A microprocessor employs a simple peak detection algorithm to detect a maximum or minimum intensity of the reflected light signal at the photodiode array, and correlates the location of the maximum or minimum intensity to the measurable parameter experienced by the optical sensor grating.
