Reflective optical sensor system for measurement of intracranial pressure Conference Paper uri icon


  • This paper describes a novel optical fiber intracranial pressure (ICP) sensor system that uses a reflective fiber optic displacement sensor to measure hydrostatic pressure. A reference reflection from a mirror incorporated into the fiber is used in signal processing to eliminate the effects of power fluctuations, loss in connector, and splices in the fiber. This sensing technique exhibits a high degree of sensitivity and linearity, and is less susceptible to environmental perturbations than current intensity modulating techniques. Experimental results are presented for measurements taken with and without an anti-reflection (AR) coating on the fiber tip facing the sensor mirror. These measurements indicate an improved dynamic range of operation for this sensor.
