abstract = "This paper presents a high-resolution dual-camera hyperspectral imager based on tunable Fabry-P{\'e}rot interferometer filter technology. By using this type of filter technology as the bandpass filter of the camera, conventional 2D image sensors can be employed to capture spectrally resolved image data. The hyperspectral instrument developed in this study consists of one camera for visible and near-infrared wavelength range, and another camera for short-wave infrared wavelength region. Both cameras are equipped with optics for high spatial resolution. In airborne measurements from an altitude of 1 km, the ground sample distance of the instrument is 6 cm and 10 cm for the visible and near-infrared camera and for the short-wave infrared camera, respectively. As a use-case example, hyperspectral airborne measurements from a helicopter are presented, along with the routine for preprocessing hyperspectral frame data captured from a moving platform. ",
