利用光谱波相互作用效应观测快速脉动目标的新技术
A Novel Technique to Observe Rapidly Pulsating Objects Using Spectral Wave-Interaction Effects
摘要：
测量快速时间变化的传统技术对于发现和观察快速脉动的天文源是低效的或不充分的。因此，可以想象，存在着一些尚未被发现的以极短周期脉动的天体。这篇文章从这样一个事实开始，即快速的磁通量变化产生一个频谱调制，可以在二次检测器的输出电流波动的拍频频谱中检测到。该望远镜可以在任何频率进行观测，尽管较短的频率具有较低的光子噪声的优势。这些技术将使我们能够发现和观察极快的时间变化，为天文学开辟一个新的时间窗口。目前的波动技术，如强度干涉仪，使用二阶相关效应，适合于目前的更新强度干涉测量的兴趣。它与强度干涉测量法的一个有趣的方面是，它可以使用廉价的大型望远镜，这些望远镜具有低质量的镜子，如切伦科夫望远镜。与测量时间变化的传统技术相比，它具有其他优点，最重要的是它的简单性。因此，它可以用于对天文源的扩展监测，这是传统望远镜难以做到的。可以说，这项技术最有趣的科学依据来自《偶然发现》
英文摘要：
Conventional techniques that measure rapid time variations are inefficient or inadequate to discover and observe rapidly pulsating astronomical sources. It is therefore conceivable that there exist some classes of objects pulsating with extremely short periods that have not yet been discovered. This article starts from the fact that rapid flux variations generate a spectral modulation that can be detected in the beat spectrum of the output current fluctuations of a quadratic detector. The telescope could observe at any frequency, although shorter frequencies would have the advantage of lower photon noise. The techniques would allow us to find and observe extremely fast time variations, opening up a new time window in Astronomy. The current fluctuation technique, like intensity interferometers, uses second-order correlation effects and fits into the current renewal of interest in intensity interferometry. An interesting aspect it shares with intensity interferometry is that it can use inexpensive large telescope that have low-quality mirrors, like Cherenkov telescopes. It has other advantages over conventional techniques that measure time variations, foremost of which is its simplicity. Consequently, it could be used for extended monitoring of astronomical sources, something that is difficult to do with conventional telescopes. Arguably, the most interesting scientific justification for the technique comes from Serendipity
