Method and System for Tracking the Centre of a Peak from a plurality of Sample Points in an Optical System

摘要

A system and method of determining the centre of a peak of data points of an optical sensor are disclosed. The method can comprise the steps of performing an initial setup measurement of the sample points and extracting a peak; fitting the peak with a function that uses at least one of the peak's width, amplitude and centre offset as fitting parameters; producing a set of linear equations which when solved calculate the optimum fit of a function to the peak assuming the previously calculated peak's width; and performing subsequent measurements of the data points to fmd peaks and solving the set of linear equations to determine the centre of the peaks.

1. A method to determine the centre of a peak of data points obtained from an optical sensor, the method comprising:
performing an initial setup measurement of sample points of the optical sensor and extracting a peak; fitting, by utilizing instructions from memory that are executed by a processor, the peak with a fitting function that uses at least one of the peak's width, amplitude, the centre offset as fitting parameters, or a combination thereof; producing a set of linear equations which when solved calculate the optimum fit of a function to the peak assuming the previously calculated peak's width; performing subsequent measurements of the data points to find peaks; and solving the set of linear equations to determine the centre of the measured peaks.
