Endoscopic Instrument Using optical fiber as a light transmission

Optical fiber endoscopy is an optical diagnostic instrument that uses optical fiber as a diagnostic and optical instrument for transmission and imaging. It can be used as a new technology to diagnose equipment. It can predict the internal changes of equipment and determine the nature, extent and potential risks of damaged parts. (1) do not disassemble the machine fiber optic transmission tube with good softness and minimum bending radius, can reach the dark long and narrow equipment, pipes, deep hole, and so on. Internal, to avoid blind removal of the machine, work convenient and effective, thereby reducing the workload and save maintenance costs. (2) the image is clear inside the machine can be bent into a variety of angles, easy to find the fault location, transmission image clarity, not only can visually observe, but also access to special accessories, camera records or video recording. (3) wide range of applications in the machine can control the end of the end of the tube can be multi-directional bending, and there are various types of glimpse to choose to use, both for the various industrial departments to check maintenance equipment, while It can also be used for research and development and manufacturing of certain new products. (4) can only check the surface defects and any other kind of detection methods, fiber optic endoscopy also has its limitations, check the internal surface defects is a powerful tool, but for the internal surface of the device defects, double spit should use other non-destructive Detection method

Endoscopy in the inspection before using the necessary calibration work in order to improve the accuracy of the latter check, the following McCate photoelectric instrument to say that the endoscopic pre-calibration work

1, under adequate lighting to observe the external surface of the endoscope should be smooth and no scratches burr plating surface should be uniform and uniform color, there should be no obvious scratches burn marks and visible cracks pinhole pits spotted burr paint or Spray the surface should be smooth, uniform color, there should be no exposed foaming at the end of cracking and so on.

2, the lighting spot at the normal working distance, placed in the test side of a white board, with the infiltration of light or endoscope comes with light source lighting, from the eyepiece or monitor with the naked eye to observe the illumination spot should be filled with field of view, no obvious Of the bright and dark areas.

3, the field of view light bar direction mark (for fiber endoscopy) in the normal working distance, placed in the test side of a white board, with the infiltration of light or endoscope light source, from the eyepiece, the field of view The light bar arrow indicates the direction of the direction mark should be above.

4, degumming or mildew at the normal working distance, placed in the test side of a whiteboard, with a dip or endoscope with their own light source lighting, from the eyepiece or monitor with the naked eye to observe, there should be no obvious degumming Or moldy phenomenon.
