Multiple light scattering caused by turbid medium can distort the propagation of waves, thus the image will become blurred. A novel method called turbid lens imaging (TLI) is adopted to reconstruct this kind of distorted images. In this method, the complex electric field of output light needs to be obtained to calculate transfer matrix of turbid medium. Only the intensity information is recorded by CCD, the phase information will be merged in recorded images. As speckle images are generated when the incident light transmits through turbid medium, there will be obvious error in the phase retrieved by using Hilbert transform directly on the interference fringe pattern. In order to eliminate the influence of speckle intensity changes, the distorted wave image, reference beam image, light interference fringe image and background image are recorded respectively. According to the interference theory, interference cosine factor can be computed, and it will retrieve phase of distorted waves more accurately by using Hilbert transform on cosine factor. In the above method, the complex electric field of distorted wave and the transfer matrix of the turbid medium are successfully calculated. It is more accurate as the amplitude is measured directly. For speckle fringe, the calculation results are much more accurate than the Hilbert transform phase demodulation results.
