A Method of Producing Testing Object in Monitoring System of Fiber Optic Taper Coupled with TDI-CCD
光锥与TDI-CCD耦合监控中测试目标的一种实现方法

To provide an effective moving resolution stripes to be tested in fiber optic taper coupled with Time Delay and Integration Charge Coupled Devices(TDI-CCD),traditional push-broom imaging laboratory sets were analyzed,and the scheme of electronic object displayed cyclically on the screen was used as an improvement. Designing idea was tested by means of optical camera static imaging and TDI-CCD camera dynamic imaging.The problem that fine resolution patterns cannot display exactly on the screen of monitor or projector was resolved by taking full advantage of the stability of moving patterns produced by optical system and the facility of electronic system on control,display and real time processing. Compared with the traditional laboratory simulative sets of the dynamic push-broom imaging the stability of stripes is improved,the mismatch between the speed of stripes and the line scanning rate of TDI-CCD was reduced.The scheme is not only convenient for coupling monitoring but also available for the image quality testing of the coupling system.
