Remote Sensing of Temperature and Speed of Sound in the Ocean

Technology

We collaborate very closely with Dr. Fry's group of Texas A&M University on the development of the technology required for this project.

Our two teams follow slightly different paths:

Texas A&M

At Texas A&M a modified, frequency doubled Nd:YAG laser as the transmitter and absorption lines of the iodine 127I2 and 129I2 isotopes as the edge filters.

TU Darmstadt

  • We are investigating the possibilities of a pulsed fiber amplifier as a replacement for the bulk Nd:YAG laser. Advantages are higher flexibility in terms of wavelength, which is desirable for our detector concept (see below) and weight. A disadvantage is the lower output power which is compensated by the higher repetition rate.

  • We are investigating the potential of an Opens internal link in current windowESFADOF (Excited State Faraday Anomalous Dispersion Optical Filter) to replace the molecular edge filters. This would have the advantage of delivering daylight suppression.
