Because the differential algorithm of facula intensity is applied, the noise and the drift of light source can be reduced remarkably. Using the linearity of differential confocal characteristic curve, the high axial resolution is achieved at a larger sampling interval.

通过使用光斑光强差动算法，可以有效抑制光源的噪声和漂移对测量结果的影响；利用差动共焦特性曲线中的线性关系，实现在较大采样间距下获得较高的轴向分辨率。

In this paper,the differential relation between optic parameter and lattice parameter in electron storage ring of HLS is presented;the lattice parameter at downriver is evaluated and analyzed when the optic parameter at upriver is changed.

研究了合肥光源储存环光学参数和聚焦结构参数间的微分关系，在改变三个输运线上游的光学参数时，计算和分析了下游各个聚焦结构参数。

One is based on the photoelectricity diffusibility reflection theory. In this method, an expensive photoelectricity sensor is laid closely with the signatures which are lightened by red LEDs. It will be judged by the analog reflection value from the detected area whether the signature is good or not. The other method uses the complex electronic image processing technology to identify some content in the signature.

一是采用光电扩散反射原理，利用特制的光传感器，在和书帖密切接触的情况下，以红色LED作为投光源照射书帖，根据检查区域内的反射光的强弱模拟量大小进行判别；二是使用复杂的电子图像识别技术，针对书帖中部分内容作图像识别。

Simulation of photon migration after entrance of tissue helps find the reasonable effective diffusive source terms.
