IR-PHI GUI

A simple graphic user interface (GUI) application that controls the infrared photothermal heterodyne imaging (IR-PHI) system.

More information about the IR-PHI technique, applications, and image restoration can be found on the web.

Features

• Imaging: Capture infrared photothermal heterodyne imaging across a predetermined area with real-time monitoring.
• Spectroscopy: Perform spectroscopy at specific points, with real-time monitoring of the process.

These features are achieved through the control of the following components:

• Mad City Labs Piezo Micropositioning Stage: Precise control over sample positioning for imaging and spectroscopy.
• M Squared Laser: Control the wavelength of the laser for accurate and adjustable imaging conditions.
• Lock-in Amplifier: Real-time signal readout and analysis for both imaging and spectroscopy applications.

Dependencies

Before running the GUI, make sure to install the required Python packages from requirements.txt.

Python Version:

This software has been tested with Python 3.8.

Required Drivers and Software:

Install the following drivers from the official sources:

• Piezo Stage (Mad Piezo drivers and Nano Drive software).
• Lock-in Amplifier (Zurich Instruments LabOne software).
• NI VISA for the functionality of the pyvisa package, which is required for communicating with the lock-in amplifier.

Following has to be configured manually:

• Lasers (M Squared). You will need to configure a static IP address for the laser control system.
• Mirror Correction Motor (Newport TRA6CC and CONEX-CC). To use these units you need to install .NET Framework 4.8.

Important Notes for .NET Integration:

• Do not install clr or pythonnet from pip.

• Install the appropriate pythonnet version manually using a precompiled wheel from this repo.

Running

To launch the GUI, use one of the following files:

• Main.py (runs with a console)
• Main.pyw (runs without a console)
