显微成像检测表面粗糙度

介绍了用显微成像检测表面粗糙度的方法。该方法具有直观，操作简单，速度快，非接触无损伤，自动检测等优点。显微成像检测表面粗糙度的原理为：被检测表面通过显微放大，由ＣＣＤ作为接收器，经图像采集卡和微机进行数据采集与处理，计算后得到相应的粗糙度。这种方法用于机械加工表面，喷涂等表面检测，对电化学处理表面，指纹，皮肤，细胞等细微结构的检测更具有优越性。

Detection of surface roughness by using micro imaging

A method for detecting surface roughness by using micro imaging has been introduced. The method has several advantages such as simplicity of operation, very fast speed detection, directly perceived through the senese, non contact, non damnification and automatic measurement. The principle of detection of surface roughness by using micro imaging is as following: the surface to be detected is elarged by microscope, and the image of which is received by CCD, then it is carried out by data collection and processing through the image collection card and personal computer, and finally, the corresponding surface roughness is obtained by computation. The suggested method can be used in the field of surface detection, such as surface measurement of mechanical processing and surface coating, particularly for the detection of surface processed by electro chemistry, as well as for the measurement of micro structure, such as fingerprint, skin and cells.
