A method of compensating for sample misalignment in an optical measurement apparatus, comprises the steps of: determining an expected response from a detector in said optical measurement apparatus given a particular set of parameters defining a path that light can take through the optical measurement apparatus from a source, via a sample, to the detector; measuring a response from the detector for the sample under test; and refining the set of parameters until the expected response and the measured response converge so as to determine the set of parameters giving rise to the measured response. |
