通过求解积分方程式,从法布里-珀罗干涉仪(以下简称F-P干涉仪)的多光束干涉强度分布来复原高分辨光谱的赏试已经在理论上取得了成功,但是在一般场合下求解这种积分方程是极不安定的,其耐噪声的能力约为10-4数量级,所以要实现这种装置至少目前在技术上还有相当困难。本文用计算机模拟实验证明在某些特定的条件下,积分方程式的求解将变得相当安定,耐噪声的能力可以提高到10-2数量级,使实现这种装置成为现实可能。The attempt to reconstruct high resolution spectrum using the interferogram of the Fabry-Perot interferometer has been achieved theoretically by solving an integral equation. But ordinarily, the solution of the equation is unstable. It is necessary to keep the antinoise ability at a level of 10-4 At present, it is very difficult to manufacture such a device, which attains this level. It is demonstrated by using computer simulation experiments that solving of the equation will become rather stable under certain conditions and the antinoise ability can be enhanced to 10-2. This result makes it possible to develop a satisfactory device.
