【摘要】 激光成像雷达可以给出目标的多方面信息,从而具有较高的目标探测和目标识别能力。其中光学扫描系统的质量是保证获得高质量二维图像的前提,因此有必要对光学扫描器的扫描性能进行定量测试,在应用光学性能扫描测试装置检测激光雷达扫描系统性能时必须保证二者的光轴是对准的。针对激光成像雷达光学扫描性能测试系统,从理论上分析了可能存在的各种对准误差,详细讨论了对准误差对光学扫描测试系统性能的影响,给出了光学扫描测试系统各种对准误差的允许范围。更多还原

【Abstract】 Laser imaging radar is capable of giving multidimensional information on an object therefore it is a better tool for target detection and target recognition.The quality of the scanner is the key element for obtaining high quality 2-D image of the target.A detection device is required to verify the scanning performance of the optical scanner.The axis of the scanning performance detection device must be is in alignment with the optical scanner of laser imaging radar.In this paper,variousvarious alignment errors that may occur in the course of measurement were analyzed theoretically for the performance measurement system of the optical scanner of laser radar.The alignment errors′ influence on the scanning performance of the optical scanner was discussed in detaile.The tolerance of various alignment errors for the optical scanning system was presented.更多还原
