Method for calibrating interpixel gains of an interferometer |
摘要 |
A method is provided to calibrate a detection array used for acquiring an image of an interferogram at an instrument. A first interferogram and at least two shifted interferograms are elaborated at the instrument by creating a number of optical path differences, so at least three samples are on a sine wave portion for each optical path difference. A function coinciding with the sine wave portion is determined by interpolation. A calibration coefficient is determined from the function for each optical path difference.
