REAL-TIME LINEAR CCD SIGNAL PROCESSING SYSTEM AND METHOD FOR MEASUREMENT OF NEAR FIELD PATTERN OF LARGE DIAMETER LASER BEAM

摘要

Linear CCD signal processing system and method for detecting a near field pattern of a large diameter laser beam in real time are provided to exactly extract a near field pattern of a large diameter laser beam by using a linear CCD(Charge Coupled Device) having a size similar to that of the large diameter laser beam. A linear CCD signal processing system comprises a system timing generator(109) for generating a synchronization clock. A beam collector partially collects a large diameter laser beam(105) in synchronization with the synchronization clock. A signal processing computer(108) detects a near field pattern of the large diameter laser beam by using the collected large diameter laser beam. The beam collector includes a partial reflection mirror(103), a linear CCD(107) and a signal processor(110).
