When the imaging system records image information by using sensor, it loses important phase information due to only record intensity information. Traditional interferometric phase retrieval techniques are restricted in their use due to the strict interference conditions. With the significant development of computational imaging techniques, the non-interference phase retrieval techniques represented by transport of intensity equation, coherent diffraction imaging, coherent modulation imaging and ptychography which are both based on CDI, have attracted great attention. They have been utilized in the field of optical measurement. This kind of techniques does not require reference light with a simple system structure, which can retrieve phase information directly from diffracted intensity images. They have great potential for applications in the measurement field. On this base, the current researches and recent progress of several typical non-interference phase retrieval techniques are presented, and the main technical features of each method are discussed and analyzed.
