Remote sensing applications with NH hyperspectral portable video camera

Abstract

Recent advances in image sensor and information technologies have enabled the development of small hyperspectral imaging systems. EBA JAPAN (Tokyo, Japan) has developed a novel grating-based, portable hyperspectral imaging camera NH-1 and NH-7 that can acquire a 2D spatial image (640 x 480 and 1280 x 1024 pixels, respectively) with a single exposure using an internal self-scanning system. The imagers cover a wavelength range of 350 -1100 nm, with a spectral resolution of 5 nm. Because of their small weight of 750 g, the NH camera systems can easily be installed on a small UAV platform. We show the results from the analysis of data obtained by remote sensing applications including land vegetation and atmospheric monitoring from both ground-and airborne/UAV-based observations.

Detection of pancreatic tumor cell nuclei via a hyperspectral analysis of pathological slides based on stain spectra

“…To obtain HSI from slides of pathological specimens, an HSI acquisition system was constructed. The acquisition system was coupled with a NH-3 (HS camera) [32] (EVA JAPAN CO., LTD., Japan) and BX-53 (microscope) (Olympus, Japan) ( Fig. 2).…”
