The invention provides a digital micromirror scanning holographic imaging method and imaging system for view field enlargement, and mainly solves the technical problem that the existing holographic imaging system is not suitable for holographic imaging under complex working conditions due to stability reduction. The imaging method comprises the following steps: 1) fixing an object to be measured in a light path; 2) scanning different areas of the object to be measured through a digital micromirror in a point light source scanning mode; the method comprises the steps of (1) adopting an image sensor to record hologram information of an object to be measured in real time, (2) adopting the image sensor to record the hologram information of the object to be measured in real time, (4) preprocessing and reproducing the hologram information, and (5) splicing reproduced holograms to complete holographic imaging of the object to be measured The method is applied to holographic imaging under various complex working cond
