ITRC of NARL announced the First Domestic Airboe Hyperspectral Imager

Instrument Technology Research Center (ITRC), one of the research institutes affiliated to National Applied Research Laboratories (NARL), announced two new hyperspectral systems on April 25, 2007, the Intelligent Spectral Imaging System (ISIS) and Farming-Use Hyperspectral Imager (FUHSI) following the successful development of the airboe multispectral imager - Vegetation and Change Detection imager (VCDi) in 2003. In Taiwan, ISIS is the first domestic hyperspectral imager operated in the visible and near-infrared bands. ISIS combined with stabilizer and POS (position and orientation system) provides wide swath and good geometric and spectral resolution. FUHSI is a scale-down version of ISIS, which enables researchers to install it on lightweight airplanes. The commands and images of FUHSI can be transmitted by wireless communication. FUHSI is an ODM (On-Demand Manufacturing) instrument which is acquired by National Chung-Hsing University and mainly applied to agriculture researches.Currently, destructive evolution in the environment have taken its toll to water resource as well as the competitive ability of local agricultural products, if not averted, which could affect Taiwan economy and ecology in the future. For example, foreign species of Leucaena glauca (L.) Benth and Mikania micrantha H. B. K are currently wide spread through southe Taiwan and ruining local ecological system. Also, the water quality in reservoirs quickly lowers after heavy rain and there are no straightforward and well-thought-of analyses to what may have caused the degradation. Aside from these, farmers need precision tools and technologies to upgrade their cultivation skills in order to survive against worldwide trade competition.Multispectral imagers, such as VCDi, could be used to distinguish features on ground, i.e. vegetation, water, and sand among others. However, it cannot address the complex problems such as distinguishing the crop and grass in vegetation area. Hyperspectral imagers are the most appropriate tools for these purposes. To date, research collaborations on ISIS for precision agriculture to predict the nitrogen content in rice and its final yield, water quality monitoring of reservoirs, and monitoring of foreign species are still ongoing. Furthermore, applications of hyperspectral imaging technique on the classification of fruits and searching of blood vessel in human arms before injection are also progressing in ITRC.More and more applications of hyperspectral imagers can be foreseen in the future. ITRC is proud of announcing these two versatile environmental surveying and monitoring systems which are the first Taiwan made instruments. ITRC will continue to provide the innovative ODM instruments to the users domestically or internationally.
