摘要: We consider how to use a charge-coupled device (CCD) as an imaging for Fabry-Perot interferometer. When the CCD is used in conventional manner (pixel by pixel readout), read noise limits its usefulness. Instead, we propose using operational mode so that 2-D circular symmetric interference pattern 1-D array. The recovery of signal effected carrying out Abel inversion show this operation it possible reduce greatly effect noise. Finally, image technique reflects on accuracy Doppler shift measurement.
