Preparation of liquid optical filters and verification of its performance through photocatalytic reaction;

A simple method has been developed to analyse the Sm-Co magnctic powder by X ray fluorescence spectrometry with solution-filter paper method.

Based on LCTF (Liquid Crystal Tunable Filter) a hyper spectral data acquisition and storing system onboard of airship is introduced in the paper.

A new multispectral image acquisition system based on liquid crystal tunable filter(LCTF) is proposed.

Photorejuveantion technology and the relative filter;

Integrated filter array fabricated by using the combinatorial deposition technique;

Striation Filter and its Optimization Method;

In addition, the methods of high-speed data acquirement, the measurement of spectral power by linear array CCD and the design of matching optical filter to accord with the standard of CIE1931 are discussed.

In this thesis the development situation and development trend of NIR spectroscopy technique are introduced and discussed, a NIR prototype machine based on LED and optical filters is designed and developed which has a lot of advantages, including portable, low cost, low power dissipation and high measurement accuracy.
