摘要
In study of ultraweak luminescence (such as bioluminescence) the weakness of luminescence or the lack of samples (photons) and the influence of system dark noise cause low SNR (signal-to-noise ratio) in photon images acquired by image intensifier. A photon image correlation integral method based on statistics and a photon image processing method based on correlation processing were proposed. The method for accumulating photon image to get enhanced SNR grey scale image was presented. A computer simulation method was developed to illustrate the process. These methods also illustrate the SNR relation between photon image and traditional grey scale image and provide an effective way for detecting ultraweak bioluminescence.
