Abstract:The optic characters of canopy reflectance spectral and the optic principle of non-destructive nitrogen monitoring were analyzed, and then the optic parameters disturbing the monitoring precision of the optic system were put forward, which included the uniformity in image optic field, the wide object field with short distance of survey, the operation dithering and the change of distance of survey. The scheme of optic system frame design, the key optic organs choosing and its optic parameters matching were proposed subsequently. Finally, the causes and control methods of the optic system measurement error were analyzed and the sample product was designed and manufactured. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
