摘要： A method and device for enhancing the power correction of optical measurements in an optical measurement arrangement, the steps including: providing a light source for producing a light beam; splitting the light beam into two beams; directing a first split light beam through an interrogation area and into an optics separation device; directing the light beams from the optics separation device and a second split light beam representing the intensity of the illumination of the main light beam of the light source into cells of a detector array; measuring and assessing the information obtained in the cells; and using this information to calculate the corrected value for the cells receiving the light beams from the optics separation device in order to adjust the power for the intensity of the light beam of the light source and/or to correct the intensity of the light beams from the interrogation area.

摘要： A method of modulating an infrared radiation (IR) source that includes applying a time-varying, periodic voltage signal to the IR source, measuring a parameter of the voltage signal, and adjusting the voltage signal to maintain a substantially constant delivered power to the IR source. Adjusting the voltage signal is done based on the measured parameter and a predetermined relationship between the measured parameter of the voltage pulse and a resistance of such an infrared radiation source. Alternatively, the method includes applying a the voltage pulse, measuring a first parameter of the voltage pulse and a second parameter of a current passing through the infrared radiation source resulting from the applying step, and adjusting the voltage pulse to maintain a substantially constant delivered power to the infrared radiation source based on the first parameter and the second parameter.
