This project is an Arduino based project that combines both simple circuit design and fabrication along with algorithm implementation on the Arduino. This project will integrate into a real research system, in the laboratory for biomedical imaging and sensing, that develop for optical detection of ultrasound.
Coherence-restored pulse interferometry (CRPI) is a recently developed method for optical detection of ultrasound that achieves shot-noise-limited sensitivity and high dynamic range. Today, the CRPI, implemented in free space Fabry-Perot, required a manual calibration process of the feedback circuit to lock the CRPI in operating state. This project core is the automation of the calibration procedure using Arduino microcontroller platform.
Project Status: Available
Project requirements:
- Design and manufacture amplifier and potentiometer PCB for the Arduino-Feedback circuit interface.
- Automation of the startup calibration of the CRPI feedback circuit using an Arduino Due microcontroller.
- Monitoring the CRPI locking state and stability during operation and modifying the calibration parameters if necessary.
