Abstract
Remote sensing is a technology which acquires the physical information of a measuring object indirectly based on the radiation acquired by a remote sensor. Therefore, to systematize the technology of converting the radiation to physical quantity is an important subject for remote sensing to spread in all the natural science fields.
We have been developed a portable line spectrum radiometer, which are constructed entirely from commercially available components. Developed radiometer has steadiness and lightness with the commercial digital camera as a measurement unit. These two features are important in field use. And, developed radiometer was proven to be effective by actually measuring the sample color chart in the relative comparison of a spectral pattern.
In this paper, we describe the instrument design of developed radiometer. Especially, we discusses it through the examination of the signal-noise characteristics based on the emphasis on the measuring a spectral pattern with the high signal-noise characteristics.
