| description | The invention relates to an encoder-free CUP-VISAR system and a fringe data reconstruction method, and belongs to the field of computational imaging. According to the method, information obtained by an integral camera is separated, on one hand, speckle noise in the collected information is extracted to serve as a reconstruction mask of a streak camera to collect an image, and stripe data is reconstructed by using an algorithm; and on the other hand, the noise of the reconstructed data is constrained by the extracted noiseless aliasing stripe information, so that the reconstruction quality is improved. According to the method, an optical coding element in an optical path of a traditional CUP-VISAR system is not needed, and noise information contained in an integral camera is used for reconstruction, so that the optical path of the system is simplified; and meanwhile, noise is suppressed and the sampling rate is increased by using noiseless aliasing stripe information in the integral camera, so that the reconst |
