1. A large-field-of-view high-resolution imaging device, comprising:
an imaging array formed by splicing and combining a plurality of imaging units and a Cesium Iodide (CsI) phosphor screen, wherein each imaging unit is formed by coupling an array of light cones in series (series light cone array) and an enhanced Charge Coupled Device (CCD);
the series light cone array is configured to conduct an optical signal and formed by connecting a large light cone and a small light cone in series, a small end face of the large light cone is connected with a large end face of the small light cone in series, 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; and
the enhanced CCD is formed by coupling the image enhancer for increasing detection efficiency and improving image brightness and contrast, and a CCD camera for converting the optical signal into an electrical signal and storing imaging information in the form of a digital signal, and a photosensitive screen of the CCD camera serves as an output window of the image enhancer.
