A device and method for phase imaging and element detection based on wavefront modulation are provided to overcome the disadvantages of an existing interferometry such as twin image elimination, limit resolution, under-sampling wavefront measurement, and multi-modal measurement. From the perspective of light field encoding, the accurate measurement to a complex amplitude of a light field to be measured is completely achieved by the iterative calculation, and at the same time, a twin image problem may be effectively eliminated, and it has the multi-modal (multi-wavelength) reconstruction ability. Theoretically, it is able to reach the diffraction limit resolution, may be widely used in phase imaging, optical element surface-type detection, polarization distribution measurement and the like, and it has a wide range of applications.

A single shot autocorrelator for measuring duration of an ultrashort laser pulse in the far field, having a beam splitter to form two beams from an input ultrashort pulse: the reflected beam is firstly reflected by two mirrors mounted on a translation stage for adjusting time delay and subsequently a third mirror, and after focused by a spherical convex lens, enters a naturally grown strontium barium niobate crystal along the crystal z axis; the transmitted beam is firstly focused by a spherical convex lens, and after reflected by two mirrors, enters the crystal along the crystal z axis from opposite direction. The crystal is in the common focal regions of two spherical convex lenses and generates the transverse second harmonic pulse beam that is the autocorrelation signal to be recorded, which is imaged with an optical microscope onto a charge coupled device camera mounted perpendicular to the beams.
