Self-mixing interferometry (SMI) is an attractive sensing scheme that typically relies on mono-modal operation of an employed laser diode. However, change in laser modality can occur due to change in operating conditions. So, detection of occurrence of mu
A tunable polarization mode dispersion (PMD) compensator based on strain-chirped fiber Bragg gratings (FBGs) is proposed. It natures in flexible designing, large tuning range, without using linear or nonlinear chirped phase mask, fast tuning response time
This work proposes a method to concurrently calibrate multiple acoustic speeds in different mediums with a photoacoustic (PA) and ultrasound (US) dual-modality imaging system. First, physical infrastructure information of the target is acquired through a
