Title:
LARGE-FIELD-OF-VIEW HIGH-RESOLUTION IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/139559
Kind Code:
A1
Abstract:
Disclosed is 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 CsI fluorescent screen. Each imaging unit is formed by coupling a series light cone array and an enhanced CCD; the series light cone array is used for conducting a light signal and is formed by connecting a large light cone and a small light cone in series, a small end surface of the large light cone is connected to a large end surface of the small light cone in series, and the large end surface of the large light cone is attached to the CsI fluorescent screen; the small end surface of the small light cone is used as an input window of an image enhancer; the enhanced CCD is formed by coupling the image enhancer and a CCD camera; the image enhancer is used for increasing detection efficiency and improving image brightness and contrast; the CCD camera is used for converting an optical signal into an electric signal and storing imaging information in the form of a digital signal; and a photosensitive screen of the CCD camera is used as an output window of the image enhancer.
