直视骄阳是危险的，只能通过适合的日食镜、配有滤光片的望远镜或者针孔投影系统观看日食。

Viewing the Sun's harsh light should only be done through protective equipment - proper solar glasses and solar telescopes, or through a pinhole projection system.

特别设计了微透镜阵列与针孔阵列对准粘接的机械和观察系统。

The mechanics and the observing system for aligning and bonding microlens arrays with pinhole arrays are specially designed.

基于点扩展函数，推导出共焦系统的成像公式，模拟了探测器尺寸对分辨率的影响，并提出最佳针孔半径。

The imaging equations are derived based on point spread function, the influence of detector on resolution is simulated, and the optimum pinhole radius is proposed.
