Abstract
A method and apparatus for monitoring one or more environmental parameters using interferometric sensor(s), a cross-correlator, a two-dimensional photosensitive array and optical focusing means are described. The method and apparatus allows for near simultaneous monitoring of the parameter(s) of interest.
Claims10
A fiber optic sensing system for monitoring an environmental parameter comprising:
- a light source;
- at least one interferometric sensor which modulates light received from the light source in response to changes in an environmental parameter;
- a cross-correlator which receives the modulated light;
- a photosensitive detector array;
- and
- optical focusing means for providing the modulated light to the photosensitive detector array in two dimensions.
A method for monitoring at least one environmental parameter using a two-dimensional detector and at least one interferometric sensor that modulates light in response to the environmental parameters, the method comprising:
- providing light to at least one interferometric sensor, said interferometric sensor modulating the light in response to a corresponding environmental parameter;
- focusing and cross-correlating the modulated light so that the light is provided in two dimensions to a detector having a plurality of light sensing units;
- and
- scanning the plurality of light sensing units to identify a correlation burst for each interferometric sensor and creating an output representative of each environmental parameter being monitored.
