"本計畫是結合國立臺灣海洋大學及國家實驗研究院儀器科技研究中心相關專家的技術合作􈙇開發並製造一個可裝載在衛星上的科學酬載“海洋環境照相儀􈙃Marine Environment Imager, MEI􈙄”􈙇 進行可行性研究。此對地觀測的分光輻射儀􈙇共有4 個波段􈙇包括3 個可見光及1 個近紅外光􈙇用來量測陸地及海洋的輻射亮度分佈及大氣的散射強度。若以衛星軌道高度700 公里􈙇此儀器地表空間解析度為500 公尺􈙇刈幅約為128 公里􈙇可用來觀測臺灣沿岸海域的浮游植物、懸浮顆粒及底質特性􈙇並可做為海上油污、海岸溢淹等災害救助。本計畫第一年期(100 年度)是設計製作一個空載的「海洋環境照相儀」􈙇完成後將在臺灣沿岸海域進行試飛拍測􈙇以了解此儀器的功能􈙇做為未來改良成為衛星酬載儀器的評估。而第二年期(101 年度)計畫將針對第一年期計畫所製作的照相儀進行振動測試並依測試結果與予優化􈙇以朝太空等級的照相儀邁進。""The main objective of this project is a feasibility study of developing and manufacturing a scientific satellite payload instrument. The instrument, Marine Environmental Imager (MEI), is being developed and manufactured by the team members with the cooperation of National Taiwan Ocean University (NTOU) and Instrument Technology Research Center (ITRC). During the first-year feasibility study period, we are developing and manufacturing an airborne MEI for testing. After it is finished, the airborne MEI will be tested around the Taiwan coastal area. The instrument is a spectral radiometer and a nadir looking imager for mapping the distribution of radiance from the land and ocean surfaces and atmospheric scattering in three visible and one near infrared bands. It is designed with a spatial resolution of 500 m and a swath of 128 km at an altitude of 700 km for monitoring the coastal environments and for disaster rescue around Taiwan. This includes the monitoring of phytoplankton, suspended particles and characteristics of bottom in the coastal waters as well as the disaster rescue of oil spills and coastal floods. In the second-year period of this study, the MEI will be done by vibration test in order to simulate the situation of satellite lunch. Then, the MEI will be optimized according the testing results to fit the requirement of spaceborne sensor."
