Abstract: A portable up-conversion fluorescent strip detector was developed to achieve the quantitative analysis of the up-conversion fluorescent strip. The performance of the detector was verified by practical measurements. The up-conversion fluorescent technology and the principle of up-conversion fluorescent strip were introduced firstly. The up-conversion fluorescent strip detector contained two critical components that were optical scanning system and electrical system, enabling the conversion of fluorescence signals to electric signals. Then, the prototype of the detector was developed and tested experimentally, therein the sampled signals detected by the strip were optimized. This apparatus proves great stability and repeatability, and the standard deviation of the detection is less than O. 004.
