Single-mode fiber-optical confocal scanning laser microscopy is a new scanning microscopic imaging system, which is based on the modern optics technology and electronics technology. The characteristic of point source and point detector removes the out-of-focus light that makes the image become blur. Therefore, it has excellent resolution in axial directions, and can achieve 3-D imaging of microorganism.

单模光纤激光共焦扫描显微镜是现代光电技术结合的新型扫描显微成像系统，其独特的点照明与点探测机理排除了离焦光线对图像造成的模糊和斑点影响，因而具有出众的轴向分辨率，能够实现对微小物体的三维成像。

Laser confocal scanning microscopy is a new technology combining modern optics and electronics. The unique feature of point light source and point detecting eliminates out-of-focus blur and spots. Therefore, the axial and lateral resolution of the system is superior and 3-D imaging can be realized by scanning point by point of the object profile. Because of its advantages, confocal measurement technology is widely applied in many fields, such as medical treatment, biology, configuration of substances and micro-electronics.

激光共焦扫描显微术是结合了现代光电技术的新型扫描显微成像方法，其独特的点照明与点探测机理排除了离焦光线对图像造成的模糊和斑点影响，因而具有出众的轴向分辨率和横向分辨率；采用扫描技术在样品表面的各点逐点扫描，能够实现对微小物体的三维成像，因此在医疗、生物、物质结构、微电子等领域均具有广泛的应用。

More recently, singular optics has been extended to polychromatic cases by Professor Wolf and his co-workers, in which they have showed that drastic spectral changes occur in the vicinity of intensity zeros in the focal region of polychromatic, spatially coherent, converging spherical waves, i.e. the spectrum is redshifted at some points, blueshifted at some other points, and is split into two peaks elsewhere.

最近，Wolf教授和他的同事们指出：在多色空间相干会聚球面波焦点区域振幅等于零的点附近会发生剧烈的光谱变化，即在一些点处光谱为红移，在另一些点处光谱为蓝移，在其它点处光谱则分裂为双峰结构。
