高分辨率天文成像的光学放大

Optical amplification for astronomical imaging at higher resolution

Gal Gumpel, Erez N Ribak

摘要:

海森堡的不确定原理告诉我们,不可能同时确定穿过望远镜孔径的光子的位置和它的动量。超分辨率成像技术依赖于对所观察到的样品的修改,或者依赖于纠缠光子。在天文学中,我们无法接近物体,但可以通过光学放大来提高分辨率。不幸的是,自发发射贡献噪声并且否定来自受激发射的可能增益。我们表明,它是可能的,以增加受激光子的重量,考虑光子统计,并观察分辨率的提高。最重要的是,我们展示了一种方法,可以适用于所有成像目的。

英文摘要:

Heisenberg's uncertainty principle tells us that it is impossible to determine simultaneously the position of a photon crossing a telescope's aperture and its momentum. Super-resolution imaging techniques rely on modification of the observed sample, or on entangling photons. In astronomy we have no access to the object, but resolution may be improved by optical amplification. Unfortunately, spontaneous emission contributes noise and negates the possible gain from stimulated emissions. We show that it is possible to increase the weight of the stimulated photons by considering photon statistics, and observe an improvement in resolution. Most importantly, we demonstrate a method which can apply for all imaging purposes.
