Electrical controller design for Fluorescence imaging system and scanning acoustic microscopy

Abstract

The modern embedded system has been largely developed in most of the current fields like industrial, medical, education, etc... It is often based on the microcontroller, combination of microprocessor, memory and peripheral interfaces to process some specific tasks in the complex system. In this thesis, for the purpose of embedded system development, we designed the electrical controller, both hardware and firmware, for two particular applications: the fluorescence imaging system (FIM) and the scanning acoustic microscopy (SAM). Firstly, the printed circuits board (PCB), with the primary components of microcontrollers and integrated circuit, is designed and fabricated. And the firmware is developed based on the manufacturer's software to perform multiple tasks simultaneously. After that, they are tested carefully in real-time, and modified several times to ensure meeting the rigorous requirements of accuracy, latency, stabilization. And finally, they are integrated to the larger system, which consists of mechanical part and other electrical part, to operate in the real condition.
