NettetIn the present work we have designed a small-size portable imaging spectrometer using linear variable interference filter, with CCD camera as picture sensor, and micromotion stage to bring along interference filter which scan across every pixel of CCD array. The difference column pixel in the pictur … NettetOverview. Benefits & Features. Applications. We have linear variable filter options for visible (VIS) or 400-700 nm, near-infrared (NIR) or 550-1,000nm, and ultraviolet (UV) or …
Ultra compact spectrometer using linear variable filters
Nettet1. jan. 2010 · Abstract. This paper presents the design, fabrication and spectral measurements of an Ultra-Violet (UV) Linear Variable Optical Filter (LVOF)-based micro-spectrometer operating in the 300 nm–400 nm wavelength range. The UV LVOF has been fabricated in an IC-Compatible process using resist reflow.

Nettet10.4 DISCUSSION. Linear filters are omnipresent in image and video processing. Firmly established in the theory of linear systems, linear filters are the basis of processing … In this paper, a linear variable optical filter for the VNIR (450–900 nm) region has been designed to serve as a spectral separation component for a hyperspectral imaging camera that can be used on earth observation satellites and airborne platforms. Traditional spectrometers based on prisms and gratings will be replaced by LVOF to fulfill ...
