Airy beam is a type of non-diffracting beam. With free-acceleration, non-diffraction and self-reconstruction characteristics, Airy beam has attracted increasing attention recently. In the research of applications of Airy beams, the self-bending trajectory modulation technique is the core technology. In this topic, we propose a defocus amount associated Airy beam modulation technology. Combined with imaging techniques, we propose an imaging technology with self-bending beams based on Airy beam. The methods of self-bending trajectory modulation of Airy beam and related technologies are studied. Based on this technique, we experimental achieve three-dimensional imaging information acquisition and anti-blocking imaging. The research includes: the theoretical analysis, deduction and reasoning of imaging technique based on self-bending beam; the design and optimization of phase plates generating Airy beams; relations between self-bending trajectories and the defocus amount; the decoding technique of Airy spot. The main innovations include: theories and experimental methods for imaging based on self-bending beams are firstly proposed; acquisition of three-dimensional information based on self-bending beams is firstly presented; an anti- blocking imaging technology is firstly proposed. This study belongs to the field of micro-and nano-optics, and the expected results can be directly applied to applications related to three-dimensional，anti- blocking imaging and other self-bending trajectory imaging system.
