The purpose of this paper was to realize a hand-held, auto-focus digital microscope system in order to observe and record microscopic images. Based on the Gauss optical theorem, we designed the algorithm and implemented it into the proposed digital microscope system. Compared with conventional optical microscopes, our digital microscope system significantly reduces the volume to only 40mm×35mm×105mm,...
Over the past few decades, a considerable number of studies have been made on biotechnology. Accompanied by the valuing of biotechnology, human beings start to put more and more emphasis on the significance of environmental monitoring, especially the measured data of bio-sensor, which needs to be analyzed explicitly. Furthermore, the measurement of behavior of micro-organism is the main method to...
In recent years, biotechnology is a highly developed and popular research topic. Microorganism behavior measurement is an important method for biotechnology experiment. Microscope is often used to measure microorganism behavior. The disadvantages of using the tradition microscope are expensive, heavy when the magnification is too large it's not easy to tracking microorganism. In this research, we...
In this paper, a digital image tracking and analysis system based on FPGA is presented. The goal of this research is to build an animal tracking system with a new algorithm for Morris water maze experiment application. Our tracking algorithm can track animal motion and is insensitive to environment brightness change. The system can process the high-resolution image up to 700times480 pixels in real-time...
In this paper, we developed a signal generation method which can be used in the interferential current electrical stimulating device. A low-cost, 8-bit microcontroller and a very compact algorithm were adopted here to generate the sine wave. Using the method, we can easily modify the frequency and phase difference between two channels with high resolution. The preliminary experiment shows that this...
