本文介绍一种光变换器。该器件由带光纤连接器的光/电和电/光转换输入输出接口及一套电路构成。从光纤传感器来的模拟光信号输入到变换器的光/电转换器件上,所得到的电信号经电路处理变成调制电脉冲,电/光转换器件将该电脉冲转换成光脉冲,再由光纤将这种光脉冲信号传至远方解调出传感信息加以利用。所研制的光变换器特性为:调制脉冲占空系数的倒数1/Q与输入光功率P成直线关系,其斜率近于0.036(1/(μW))。对于光纤传感系统来说,其传输距离已几乎不受限制。
This article describes a light converter. The device consists of an optical / electrical and optical / electrical conversion input and output interface with a fiber optic connector and a circuit configuration. The analog optical signal from the optical fiber sensor is input to the optical / electrical conversion device of the converter, and the obtained electric signal is processed into a modulated electric pulse by a circuit, and the electric / optical conversion device converts the electric pulse into a light pulse, Optical fiber will be transmitted to the distant light pulse demodulation of sensing information to be used. The characteristics of the developed optical converter are as follows: The reciprocal 1 / Q of the modulation pulse duty cycle is linear with the input optical power P, and its slope is close to 0.036 (1 / (μW)). For fiber optic sensing system, its transmission distance has been almost unlimited.
