How to reduce the noise impact and improve the detection accuracy? |
* Answer
1 multiple average.Since the noise is random, the effect of noise can be reduced by multiple sampling averaging.Multiple sampling and averaging of the signal can be conveniently done by a microcomputer.
2 curve fitting method.The curve fitting method can greatly reduce the influence of random factors, and the measurement accuracy is obviously improved, and the curve fitting method has an obvious advantage that the resolution is not limited by the size of the array unit. 3 more dark point position fitting method. |
