Research on the enhancement of signal-to-noise ratio of light-addressable potentiometric sensor by optical focusing
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.
