中文摘要：

为提高光设法解决的 potentiometric 传感器(臀部) 并且进一步的反应改进它的信号 -- 噪音比率(SNR ) ，一个光集中方法被采用。试验性的研究和理论分析表明应答的信号的大小被光集中增加，并且 SNR 显著地被改进。这些研究结果显示光集中是为改进臀部的 SNR 的一条有效途径。

英文摘要：

For enhancing the response of light-addressable potentiometric sensor（LAPS） and further improving its signal-to-noise ratio（SNR）,an optical focusing method is adopted.Experimental research and theoretical analysis reveal that the magnitude of responsive signal is increased by optical focusing,and the SNR is improved remarkably.These research results indicate that the optical focusing is an effective approach for improving SNR of LAPS.
