Interferometry techniques are essential for extracting phase information from optical systems, enabling precise measurements of dispersion and highly sensitive detection of perturbations. While phase sensing offers enhanced sensitivity compared to conventional spectroscopy methods, this sensitivity often makes systems more vulnerable to external factors such as vibrations, introducing instability and noise. In this work, we demonstrate a broadband and AI-enhanced interferometry method, denoted general polarization common-path interferometry (GPCPI), that relaxes the polarization...

We have used PMUTs for 3D imaging. based on a 4×4 bimorph, pinned dual-electrode PMUTs array with the transmission beamforming scheme. This project advances the ultrasound-based imaging technique by using the compressed sensing scheme. The goal is to achieve 3D imaging with a low number of transducers and minimum computation for various applications in robotics, wearable electronics, autonomous navigation, and medical diagnostics.
