The thesis adopt the study method combines optical test, theory analysis with numerical simulation, acquired the following main achievements:(1) the dynamical characteristic trial on rocks specimen under dynamical loading, reveal the rmation, wreck characteristic of rocks under long time cyclical dynamical loading.
This system can offer plentiful modern optical test experiment and improve students' study interesting, especially in info technique, instrument science, measurement and automatic techniques major.
1. Based on reading a great deal of literature relative to the quantitative analysis method of microstructure and experiment means at home and abroad, the micro structural static optical test system was evolved into ATOTS, by doing so, multi-condition researches of soil microstructure can be taken.
In contrast, optical test of free-form optics is relatively a new technique. There are not only problems of analysis software, but first a lack of proper means.
The paper discovers a method,by which the imbalance force and coupling are balanced simultaneously with the utilization of balancing machine and optical test platform with a simulating target.
Meanwhile, the performance of the IHOS is discussed, the diffractive efficiency of DOE, the variation of the environment temperature, and the scattering light are also discussed. Finally, the testing techniques of the IHOS are studied, based on the currently existed testing methods, combining the specific features of the IHOS, we setup the testing theory of the IHOS, and completed an infrared hybrid optical testing system, which leads to a research on the performance of the IHOS.

Digital Doting Image Correlation method (DDIC) is the production of the modern digital image processing technology and photo mechanics. It is based on the Digital Speckle Image Correlation (DSCM) method which is a optical measurement whose usage is more narrower than the former.
Optical test results showed that clear eye-diagrams can be obtained at 155 Mbps, with the output optical power being nearly constant, and the variation of extinction ratio being lower than 0.7 dB.
Fused fiber coupler's optical performances such as insertion loss, excess loss, directivity and uniformity were tested with the optical test system that was constituted of tunable laser and optical spectrum analyzer.
Investigations on the stimulation of glutathione reductase of human erythrocytes by riboflavin and FAD showed the following results:1In glutathione reductase deficiency, the enzyme activity in the optical test was normalized by addition of FAD.
