“…Recently, hyperspectral imagers that acquire data within a single snapshot have gained increasing attention to image dynamic scenes. Hyperspectral capture technique generates a map of spectral information, making it an important tool in many diverse applications, including remote sensing [1], military target discrimination [2], astrophysics [3] and computer vision region [4,5]. A hyperspectral imager measures a detailed spectral signature at each pixel in an image.…”

In this paper, we propose an advanced hyperspectral video imaging system (AHVIS), which consists of an objective lens, an occlusion mask, a relay lens, an Amici prism and two cameras. An RGB camera is used for spatial reading and a gray scale camera is used for measuring the scene with spectral information. The objective lens collects more light energy from the observed scene and images the scene on an occlusion mask, which subsamples the image of the observed scene. Then, the subsampled image is sent to the gray scale camera through the relay lens and the Amici prism. The Amici prism that is used to realize spectral dispersion along the optical path reduces optical distortions and offers direct view of the scene. The main advantages of the proposed system are improved light throughput and less optical distortion. Furthermore, the presented configuration is more compact, robust and practicable.
