Selection and Research of Methods Increasing Optical Boundaries Determining Accuracy of Objects Suitable for Further FPGA Implementation

The article describes an optical method for obtaining the geometric parameters of an object, based on the analysis of the boundaries of the object’s shadow in a divergent light flux. One of the main tasks that arises when using this method is filtering a noisy signal in real time with a high frequency. The article discusses and compares two photo signal filtering methods using FPGAs.
