The invention relates to a three-dimensional real-time super-resolution digital holographic recording method, belonging to the technical field of three-dimensional micro-imaging. The method provided by the invention comprises the following steps of: by utilizing wavelength division, angular division, time division and polarization hybrid multiplexing technologies, dividing laser sources into two beams of pulse lasers with different wavelengths and a time interval through a series of optical elements; dividing each beam of pulse laser into two beams of irradiation light and two beams of reference light, wherein the two beams of irradiation light respectively irradiates a measured object from different directions so that the low-frequency information and high-frequency information of the measured object are transferred to a digital camera recording surface by permeating through a micro objective to interfere with the corresponding reference light; recording two transient moments of the measured object in one frame picture of the digital camera, and recording four digital holographs containing the high-frequency information and low-frequency information; and then, transmitting the recorded image into a computer to be processed so as to acquire a three-dimensional real-time super-spatial resolution reproduced image by utilizing an image processing system. The method provided by the invention has the advantages of recording much information, breaking through the limit resolution of an imaging system, simultaneously improving the spatial resolution and time resolution, and the like.
