摘要	本实用新型涉及一种相位解调式石油烃类污染物鉴定装置，装置中控制器输出控制信号至光源模块，光源模块输出的光源照射到采集模块中的样品池中；信号采集模块采集被测样品激发的光传送至数据转换模块，数据转换模块与控制器进行双向连接；光源模块中第一激光二极管和第一准直透镜的几何中心在一条直线上；第二激光二极管和第二准直透镜的几何中心在一条直线上；由第一激光二极管到第一准直透镜的射线与由第二激光二极管到第二准直透镜的射线同向平行；第一准直透镜与第二准直透镜与样品池相邻。本实用新型鉴定速度快、不会产生其它污染；采用双通道光源结构，能够产生稳定、充足的光源，各通道之间信号传输隔离、独立，具有极高的测量准确性。
其他摘要	The utility model relates to a phase demodulation type petroleum hydrocarbon pollutant identification device, which is characterized in that a controller in the device outputs a control signal to a light source module, and a light source output by the light source module irradiates into a sample pool in an acquisition module; wherein the signal acquisition module acquires light excited by a testedsample and transmits the light to the data conversion module, and the data conversion module is in bidirectional connection with the controller; the geometric centers of a first laser diode and a first collimating lens in the light source module are on the same straight line; the geometric centers of the second laser diode and the second collimating lens are on the same straight line; rays from the first laser diode to the first collimating lens are parallel to rays from the second laser diode to the second collimating lens in the same direction; the first collimating lens and the second collimating lens are adjacent to the sample cell. The identification speed is high, and no other pollution is generated; a double-channel light source structure is adopted, a stable and sufficient light source can be generated, signal transmission between channels is isolated and independent, and extremely high measurement accuracy is achieved.
