【 摘 要 】

Fabry-Pérot interferometers are commonly used as tunable filters in a variety of scientific fields. We here consider the use of a single Fabry-Pérot as a universal tunable filter in hyperspectral imaging applications, when it is necessary to recover image information of the scientific target at different wavelengths. Fabry-Pérot are commonly used to scan small portions of the spectrum, defined by suitable prefilters. This is necessary due to the multi-peak response of a single interferometer. In order to overcome this issue we propose a novel triple-pass configuration, able to provide a fast and continuous sampling of the electromagnetic spectrum in the visible-infrared range without the need for a collection of dedicated prefilters.
