A novel high-resolution and large-range autocollimator measurement system for roll angle is proposed. The system retains the basic internal structure of the traditional autocollimator (AC), which only uses a novel non-standard cylindrical cube-corner reflector (CCCR) instead of the planar reflector. In the article, the mathematical relationship between the structure of this special reflector and the spatial coordinate vector change of the reflected beam is deduced, and the measurement formula of the roll angle autocollimator (RAC) measurement system is established based on this mathematical relationship. The effectiveness of the measurement system and method is verified by experiments. Experimental results show that this method can effectively enhance the range to ±20°, and the whole measurement accuracy is 6.1", the measuring resolution is 1".
提出了一种新型的用于测量横滚角的高分辨率、大测量范围的自准直仪测量系统。该系统保留了传统自准直仪（AC）的基本内部结构，只是使用了一种新型的非标准圆柱形角锥反射镜（CCCR）来代替平面反射镜。文中推导了这种特殊反射镜的结构与反射光束空间坐标矢量变化之间的数学关系，并基于此数学关系建立了横滚角自准直仪（RAC）测量系统的测量公式。通过实验验证了测量系统和方法的有效性。实验结果表明，该方法可有效将测量范围提高到±20°，整体测量精度为6.1"，测量分辨率为1"。
