Overview

This repository contains code and resources for a Fourier ptycography system, which uses computational imaging to achieve high-resolution microscopy through multiple low-resolution measurements.

Repository Structure

• /Arduino - LED Matrix Control System

  • Ptycography_LED_matrix_program - Control software for the LED matrix
  • Libraries for LED matrix, pattern generation, and camera control

• /Media - Example images and MATLAB code

  • Resolution target images
  • Reference implementations
  • Comparison images

Arduino LED Matrix Controller

The Arduino directory contains a complete system for controlling an LED matrix for Fourier ptycography experiments:

• Modern Processing-based central controller
• Arduino firmware for hardware control
• Camera triggering and synchronization
• Visualization tools
