A four-quadrant photocell is used in the system to replace photoelectric cell, and it ACTS both as centering detector and lightintensitydetector.
测试系统中使用四象限光电池代替一路光电池进行差动运算,四象限光电池同时兼有对光和光强检测的功能。

When a catalyst plug passes through the conduit it blocks the light path and thus the lightintensity recorded by the detector drops.
当催化剂栓柱通过管道时,它遮断光路,因此检测器记录下的光强降低。

The light optical spot area and the optical intensity distribution can be adjusted through software. The non-uniformity of response and the SNR are influenced by the noise of the detector.
