在本文中，我们提出了一种用于高分辨率成像的天文光光学混合分析（ALOHA）仪器的多通道光谱配置。在干涉仪的每个臂上实现频率转换过程，以将天文光转移到较短的波长域。利用这种非线性光学过程的光谱选择性，我们提出使用一组独立的泵浦激光器来同时研究多个光谱通道。该原理通过双通道配置的实验证明了其原理。
In this paper, we propose a multichannel spectral configuration of the Astronomical Light Optical Hybrid Analysis (ALOHA) instrument dedicated to high resolution imaging. A frequency conversion process is implemented in each arm of an interferometer to transfer the astronomical light to a shorter wavelength domain. Exploiting the spectral selectivity of this non-linear optical process, we propose to use a set of independent pump lasers in order to simultaneously study multiple spectral channels. This principle is experimentally demonstrated with a dual-channel configuration as a proof-of-principle.
