  • Multiple resonance grating

    Multiple resonance grating

    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.Read More »

  • EOM-PI low bandwidth demodulation and sampling -Taken

    EOM-PI low bandwidth demodulation and sampling -Taken

    In the development of Electro-Optic Modulated Pulse Interferometry (EOM-PI) emerged the need for the development of a technique for sampling the EOM-PI signal with low bandwidth sampler (~10MHz) rather than the 1.5GHz sampling bandwidth implemented today. Furthermore, a development of demodulation algorithm for the sampled signals to retrieve signal’s phase.Read More »
  • Laser Speckle Contrast Imaging on RaspberryPi -Done

    Laser Speckle Contrast Imaging on RaspberryPi -Done

    Laser Speckle Contrast Imaging (LSCI) is an imaging method used in diffusive media. This method maps the regions of dynamic scatters, i.e. blood flowing in blood vessels. Due to developments in both cameras and miniaturized computers, LSCI systems may be implemented in a small cost efficient system, such as a RaspberryPi platform.Read More »

    TM Beam Propagation in Photonic Integrated Circuits -Done

    Optical detection of ultrasound is mostly done with high-Q factor optical resonators. These optical resonators can be manufactured in Silicon wafers, where the resonators spectra are highly sensitive to the polarization state of the propagating beam. TM polarized beam can potentially increase manufacturing yield as well as sensing sensitivity by an order of magnitude.Read More »
