Abstract
A signal processing apparatus which has an input for receiving a signal conveying a response from first and second optical components to an optical excitation. The first and second optical components are in an optical sensor which is intended to be placed in a sensing zone. The sensing zone contains hydrogen susceptible to migrate into the optical sensor. The signal processing apparatus has a processing entity for processing the response from the first and second optical components to derive information on hydrogen concentration in the optical sensor.
