It is well known that spectroscopic measurements suffer from an interference known as stray light, causing spectral distortion that reduces measurement accuracy. In severe situations, stray light may even obscure the existence of spectral lines. Here a novel general method is presented, named Periodic Shadowing, that enables effective stray light elimination in spectroscopy and experimental results are provided to demonstrate its capabilities and versatility. Besides its efficiency, implementing it in a spectroscopic arrangement comes at virtually no added experimental complexity.
众所周知，光谱测量会受到一种称为杂散光的干扰，导致光谱失真，从而降低测量精度。在严重的情况下，杂散光甚至可能掩盖光谱线的存在。本文提出了一种名为周期遮蔽的新颖通用方法，该方法能够有效消除光谱学中的杂散光，并提供了实验结果以证明其能力和通用性。除了效率高之外，在光谱装置中实施该方法几乎不会增加实验复杂性。
