Remote Sensing of Temperature and Speed of Sound in the Ocean

Latest Results

First temperature profile measurement in our testing setup. So far the results are not taken in real time (left).

  • Transmitter System

    A five-stage, frequency doubled Yb-doped fiber amplifier has been set up.  For 10 ns pulses we can generate more than 0.5 mJ/pulse energies in the green spectral range.

  • Receiver System

    Our approach for an edge filter has been successful. By the use of a modified Halbach cylinder we were able to generate an ESFADOF with the edges at the correct spacing and peak transmission up to 80%.
