Fluorescence based sensors are widely used in the field of biochemistry and medicine due to their high sensitivity and accuracy. But the cost and time required for each sample to be tested is high. If the diagnostic tools could be miniaturized, made simple to use and much less expensive, and readily available at the point of need such as emergency diagnosis, millions of people would be benefited from it. In this paper, we design a prototype of portable fluorescence detection system based on Fluorescence Filter Block and DAQ card which can emulate signal collection and processing functionalities. After the introduction of system structure and functional modules, we use a resolution approximation method to investigate the system performance. The evaluation shows that our prototype system has the sensitivity of 0.01 mMol/L (333.306 mu g/mL) which meets most of the medical requirements.
