Using the present cone beam reconstruction formula for general trajectory, we have investigated the issue of detector efficiency for non-helical trajectory.
基于现有的锥形束普适轨道的重构公式,研究了非螺旋轨道的探测器效率问题。

Thebeam expanding system has some advantages of fewer lenses, simple structures and smoothly zoom trajectory, and it is suitable for simulating lighting elements with different sizes.
系统具有镜片少,结构简单,变焦轨迹平滑无卡滞等优点,可用于模拟不同尺寸的闪电单元。

It is shown that the ray trajectory depends strongly on the spot size and the inclination of the incident beam and the structure of the lens.
