Abstract： |
A digitalized laminagraphic system with near infrared diffusion features that a multi-channel optical fibre switch has an input connected to the output of a laser device and multiple output surrounding a position to be tested, which is also surrounded by multiple photoelectric sensors for detecting the reflected and transmission light. Each photoelectric sensor is connected to an amplifier. All amplifiers are connected with a data acquisition card of computer. |
