A Simple and Efficient Microstructure Optical Fiber End-face Imaging System

Abstract

The invention relates to a simple and efficient microstructure fiber end face imaging system and belongs to the field of optical application of photoelectrons, lasers and optical fibers. The simple and efficient microstructure fiber end face imaging system comprises a laser device, a CCD detector, a varifocus lens group, a microscope objective, an optical fiber coupling rack, a pair of high-reflection low-transmittance reflectors, a collimator and the like, wherein the microscope objective is multiplex, and the varifocus lens group conducts variable power imaging. Lasers are collimated, focused onto the coupling rack through the microscope objective and transmitted to a fiber end face; after light arriving at the fiber end face and reflected back passes through the microscope objective again, the varifocus lens group conducts variable power imaging, and the light is focused onto the CCD detector finally and subjected to data processing to form a visible image to be displayed on a computer, so real-time monitoring on the fiber end face is achieved. Through imaging of the fiber end face, the microstructure fiber end face can be observed and compared efficiently and specifically, and the simple and efficient microstructure fiber end face imaging system can be applied to multiple fields such as optical fiber coupling and optical fiber microprocessing.
