摘要：
We demonstrate a lensless terahertz phase retrieval imaging technique with a point radiation source. In contrast to the conventional applied multiple-plane iterative phase retrieval method, an algorithmic method to accelerate the phase retrieval process is proposed by using a randomly ordered sequence of propagations. The experimental results demonstrate that the method can improve the convergence speed by 2 to 3 times and reduce the number of needed intensity measurements for the iterative retrieval.
