Abstract:
1. A method for optimizing the power correction to the light intensity used as a signal in an optical measurement arrangement, the steps comprising: a) providing a light source for producing a light beam; b) directing the light beam into a beam splitting device to produce a first split light beam and a second split light beam; c) directing the first split light beam through at least an interrogation area and an optics separation device for separating the first split light beam into one or more light beams; d) providing a detector array assembly having a plurality of detection elements for receiving the one or more light beams of the first split light beam and the second split light beam; e) directing the one or more light beams of the first split light beam and the second split light beam into one of the plurality of detection elements of the detector array assembly to provide information regarding the detected light of the first and second split light beams; f) measuring and assessing the information obtained in at least the detection elements of the detector array assembly which received the one or more light beams of the first split light beam and the information obtained in one of the plurality of detection elements of the detector array assembly which received the second split light beam; and g) using this information obtained in step f) to adjust an optical power level of the light source to adjust the intensity level of the light beam of the light source.
