Abstract

Optical design of Air.bone liaging Spectroieter is described in this study. A new design of push.brooi type liaging Spectroseter using lens, prisa and CCD sensor systei is cospared to classical Isaging Spectrometers those were composed of all reflecting optical components. Advantage of using refracting elements against that of using mirror and reflection grating is the design flexibility of optical components and possibility of reducing and correcting many kind of aberrations. Disadvantage of lens system - chromatic aberration - is reduced to be negligibly small within 0.4 to 1.0 jim by selecting glass materials. The purpose of Imaging pectrometer is to monitor life conditions of vegetations from high altitudes by measuring spectral reflectance of foliage (chiorophyl). By such purpose, wavelength was limited from visible until near IR region.
