The purpose of this research to design the bliid cell counting indtrument which can measure the number of RBC(Red blood cell) and WBC(Which Blood Cell) incluing many other blood componenent. The proposed method uses the electrical impedence method and the new discrimination method with DSP chip and sortware algorithm. The system consist of control unit, blood cell discrimination unit, hemoglobin spectrometer, post detection processor unit, and IBM-PC interface unit. In this paper, the discrimination system has been implemented using digital signal processor, which result in the reduction of system hardware and cost. The system is helpful in providing necessary clinical test for screen test and quality control of hematology.

Measuring thickness of resin using a machine vision system and image processing is presented in this research. A machine vsion System is one of the essential parts in order to inspect nano/micro patterns transferred by nanoimprint. Thickness of cured resin is determined from the relative distance between substrate and mold. For the measuring thickness, A machine vision system and image processing are used. A machine vision system which takes a focus on substrate and patten find out relative distance. Also it was possible for measured data to make more precise by image processing.
