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.
