A large-field-of-view high-resolution imaging device includes an imaging array formed by splicing and combining a plurality of imaging units and a CSI phosphor screen. Each imaging unit is formed by coupling an array of light cones in series and an enhanced CCD. The series light cone array is formed by connecting a large light cone and a small light cone in series such that a small end face of the large light cone is connected with a large end face of the small light cone, a large end face of the large light cone is attached to the CSI phosphor screen, and a small end face of the small light cone serves as an input window of an image enhancer. The enhanced CCD is formed by coupling the image enhancer and a CCD camera. A photosensitive screen of the CCD camera serves as an output window of the image enhancer.
