摘　　要：滚仰式光学滑环被广泛应用在小型化位标器中。由于引入了折转光路,其对目标的空间角位置测量比传统的跟踪成像系统更复杂。基于光线反射定律和等距变换理论研究滚仰式光学滑环对目标的空间角位置测量,得到理论计算公式和近似计算公式,最后通过数值仿真验证了分析结果的正确性。Roll-pitch seeker with slip chain is widely used in miniature seekers. Because of introducing reflective optical paths, the measurement for the angular position of the target in the space is more complicated than traditional imaging tracking systems. Based on the law of reflection and equidistant alternating theory, roll-pitch seeker with slip chain is studied to measure the angular position of the target in the space. The theoretical calculation formula and the approximate formula are obtained. At last, the analysis results are tested by numerical simulations.
