Near-infrared spectroscopy was used to examine unmodified wheat powder at temperatures of 14-65C. A self-regulating diffuse reflected assembly was used to permit collection of spectra of powder samples. Changes to the shape and peak location of the 1400-1500nm and 1900-1950nm water absorption bands  2000-2050  2070-2110 and 2250-2300nm bands were measured as temperature varied. Results indicated that temperature changes resulted in slight changes to the water absorption bands in 1400-1500nm and 1900-1950nm regions. From 14-65C  the 1400-1500nm and 2050-2150nm band shifted approximately 10nm and 16nm toward shorter wavelengths  and 2000-2050nm band shifted approximately 14nm toward longer wavelengths. In addition few numbers of samples cannot constitute good temperature insensitive calibration model even though the spectra were obtained at wide temperature condition.

Based on laser optical triangulation displacement and grating displacement inspecting principle  optoelectronic non-contact inspecting method and inspecting system for the taper of small-calibre bore are presented. In this paper  the constitute and overall structure of the system are described. Then  the taper inspecting method and principle of the bore are discussed and theoretically analyzed  and also  the corresponding mathematics model is established. As inner diameter measurement is an important parameter for the taper of small-bore  an inner diameter laser non-contact measuring method is presented based on the structure characteristic of the taper of small-calibre bore  which adopted optoelectronic probe sensitive device (PSD) and laser optical triangulation inspecting principle. And then  the laser probe inner diameter measuring system is designed based them. Moreover  the measuring principle  the project of optical system of this measuring system are illuminated in detail in this article. The accuracy of inspecting system is verified by experiment. The results showed that the measuring error of inspecting system is superior to 0.005  and the inspecting repetition is superior to 0.003. It indicates that the system can fulfill the inspecting accuracy demand for inspecting the taper of the small-calibre bore  and the inspecting method is applicable.
