Silicon retina: Focusing on motion studies for detecting the x-axes and y-axes
Abstract
The purpose of this report is to explore how to build a circuit that works as a human retina, which can detect motion. The whole project is divided into five steps, which include researching, simulating, building a cell on the breadboard and testing, presenting a cell on Printed Circuit Board and testing, printing more cells, and connecting all the cells. Through each step of the execution, the output signals from the x-axis and y-axis become more and more accurate, in other words, the speed measured by the entire retinal system becomes more and more accurate. When connecting the photoreceptor as the input, different motion types, which include moving fast or slow, moving horizontally or vertically, and moving upward at an angle or downward at an angle, and the results are also basically following the analysis and the expected result read from the books or journals. The errors are mainly caused by the different light conditions in the environment.
