Distortion measurement with inverse imaging method

  • 摘要: 在相对畸变的定义下,提出了逆向成像畸变测试方法。通过把目标靶尺放到被测系统的焦面位置,再将被测光学系统的入瞳位置放到精密转台的转轴位置,将被测光学系统从正向最大视场处向负向最大视场处旋转,测量14个视场点后,可得到各个视场的畸变值。该方法严格要求把被测光学系统的入瞳位置放置在精密转台的旋转轴上,否则无法测量出整个视场的畸变值。焦距测量精度达2 m,畸变测量精度达5.010-4。
    Abstract: According to the definition of relative distortion, a distortion measurement with inverse imaging method was proposed. We first placed the target on the focus surface of the unit-under-test (UUT), put the entrance pupil position of the UUT at the rotation axis position of the precise turntable, and rotated the UUT from the forward maximum field of view (FOV) to the negative maximum FOV, then measured 14 FOV points and finally obtained the distortion value of each FOV. Distortion value of the whole FOV could not be measured unless the entrance pupil position of the UUT was put at the rotation axis position of precise turntable strictly. The accuracy of focal length measurement is 2 m, and the accuracy of relative distortion measurement is 0.5.
