用电弧作光源时，观察到组织结构的不同使定标曲线发生平移，用火花光源时这种现象并不显著。

The small hole of the optical inducer of the traditional second-generation optical mouse used for receiving the images faces downwards, and corresponding light sources (including photoelectric diode and laser diode), optic lens and photosensitive holes are arranged at the lower part of the mouse; therefore, moving the whole mouse is a relatively convenient method for generating displacement of the mouse pointer; oppositely, the small hole of the optical inducer used for receiving the images faces upwards and corresponding light sources, optical lens and photosensitive holes (7) are arranged at the upper part of the mouse; matters on the upper surface of the photosensitive hole (7) can be moved so as to lead the mouse pointer to generate the displacement, while the moving signal transmitted by a photoelectric conversion device must be reset so as to comply with the integrated mouse of the invention.

传统的第二代光电鼠标的光学感应器接收图象的小孔是向下的，对应的光源(包括光电二极管，激光二极管)、光学透镜和感光孔都是在鼠标下部分，这样要想鼠标指针产生位移较方便的方法就是移动整个鼠标；相反，光学感应器接受图象的小孔向上，对应的光源、光学透镜和感光孔(7)在鼠标上部分，要使鼠标指针产生位移就只需移动附在感光孔(7)上面的物质，但必须重新设置光电转换装置传出的移动信号，以符合本发明。

Firstly, the soil samples are gathered from the same section such as surface layer soil samples gathered from 0cm to 15cm depth and representation on studied object. Secondly, the precondition of tested samples must be the same. This study indicates that the tested samples must be 1mm diameter, over-dried at 40℃ for 24h and airtight cooling for 24h before measured for air-dry samples, and softly planish the surface at measuring. Lastly, the illuminating condition of light must be the same. This study indicates that the testing geometric condition are light source angle 15°, light source distance 30cm and sensor distance 15cm for soil hyperspectra indoor. The surface of white reference must be the same plane of that of sample.

第一个环节的"相同"是指田间土壤样品采集时的剖面位置一致，如表层土都采集0～15cm深度范围内的土壤，且所采集的样品应能尽量具备研究对象的代表性；第二个环节的"相同"是指土壤制备过程中的一些前处理条件应一致，建议土壤光谱测试样品的粒径1mm，风干土壤样品测试前在40℃恒温条件下烘24小时，然后密闭冷却24小时，测试时土壤表面进行稍稍压平处理；第三个环节的"相同"是保证测试光照条件的一致性，建议在50W卤素灯、8°探头角条件下，采用15°的光源照角度、30cm的光源距离和15cm作为室内士壤高光谱测试几何条件，测试时除遵循光谱测试指南的要求外，还须保证参考板表面与测试土壤样品的表面在同一平面上。

Open Linear Encoder includes main grating scale and optical encoder head. This optical encoder head includes LED light source, optical detector module, and secondary phase-grating. LED light will pass through the plano-convex lens and produces parallel light. As the parallel light pass through secondary grating, the quadratic image display on the main grating scale. And the Moire interference will be reflected from the main grating scale and detected by optical detector module, as there is a relative shift between the main and secondary grating. From detecting the periodic sinusoidal signal with phase difference 90°, the period represents the grating pitch, using the counter to detect the number of periodic signals to get the displacement, and we can adapt the technology of electron subdivide further to increase the resolution of measurement .

反射式光学尺包括主光栅尺及光学读头，光学读头包含LED光源、光侦测器模组及相位式副光栅，LED光源经平凸透镜，产生平行光穿透副光栅后，副光栅之二次成像投射在反射主光栅尺上，当主、副光栅因相对运对产生之Moire干涉经主光栅尺反射至光电检测器，检出相位差90°之周期性弦波讯号，其周期代表栅距，因此可用计数器检出周期性讯号数目得到位移量，可进一步采用电子细分割技术提高解析度。
