A DEMODULATION SCHEME BASED ON MEASURING INTERFERENCE FRINGE VISIBILITY WITH A HIGHLY BIREFRINGENT FIBER BASED MICHELSON INTERFEROMETER

We propose a novel demodulation scheme based on measuring interference fringe visibility and demonstrate it using a typical Michelson interferometer (MI) configuration.The key component to achieve the scheme is a section of highly birefringent fiber (HBF) spliced into the sensing arm to function as the sensing element.The optical path difference (O

Aims: COVID-19 patients with comorbidities such as hypertension or heart failure (HF) are associated with poor clinical outcomes.The cellular distribution of Angiotensin-converting enzyme 2 (ACE2), the critical enzyme for SARS-CoV-2 infection, in the human heart is unknown.We explore the underlying mechanism that leads to increased susceptibility t
