Abstract

Abstract:

Keeping the diffuse reflection reference plate in leveling status in the process of field spectral measurement was helpful in reducing the uncertainty of the solar incidence angle into the reference plate. In order to reduce the operation strength of the field spectral measurement and to improve the measurement efficiency, a platform that can level the reference plate rapidly was designed and realized by using the digital signal controller TMS320F2812, inclinometer SCA100T-D01 based on the 3-dimension MEMS technology, and step motors comprised of a close-loop control system. The operation principle of the auto-leveling platform was introduced, and the hardware and software of the control part of this auto-leveling platform were descript part by part in detail, and the system operation flow chart was conducted, too. Compared with the traditional leveling method, that levels the reference plate manually by using the level ruler, this platform carries the characteristics of rapidity and high accuracy.

Key words: field spectra measurement, auto-leveling, inclinometer
