Portable and wireless quantitative phase microscope

Wireless communication can break the limitations of space and enable data transferring between disconnected equipment. Automatic and remote-controlled experimental equipment is required for factories or when it is inconvenient to work in the lab, e.g., during the pandemic. We implemented and demonstrated a wireless and automated quantitative phase microscope (QPM) system which can be used for observation of samples remotely or in a confined space. Microscopic manipulations, such as sample placement and scanning, can be operated through a robotic arm and motorized stages controlled by an embedded computing board equipped with a Wi-Fi connection.
