This article describes a variety of chromatic polarization experiments with the readily available sticky tapes in place of wave chips and sums up the law of the light intensity,colorimetric purity and the position of color changes in the chromatic polarization through theoretical analysis and experiments.

In order to correct secondary spectrum and distortion, equal position chromatism and equal spherical aberration are retained in front and raer group in the long focu system, and the values of front is minus in positive optical path and raer plus in opposite.

This paper probes into the research and development of a new type of coloring device of projecting lights.

Using the measured dry-leaf biochemistry and hyperspectral reflectance data,a new thinking clue of leaf biochemical retrieval is developed based on the 1st derivative extremum of area-nomalized hyperspectral position variables.
