Abstract
A liquid sensing system based on a dual-channel and concave-shape optical coupling sensor array is developed for in-situ and quantificational measurement of a liquid sample. The principle and implementation of this system are introduced. The pH measurement for a bromcresol green liquid sample is made using the present sensing system and compared with the result from a spectrometer. The result consistently demonstrates the feasibility of the novel method and validity of the sensing system.
