Abstract: A new instrument for remote ice detection and thickness measurement is described. It incorporates two optically based technologies that give it capability to measure the thickness of clear or foggy layers of solid or liquid on surfaces. The prototype device, known as RIDE (Remote Ice Detection Equipment), is capable of measurements on moving surfaces such as wind turbines, and aircraft propellers and rotors. The current RIDE prototype is intended for relatively long distance measurements however a small, and much simpler, version of the technology is planned for short distance measurements (within a few meters). In the marine context a miniaturized version of the device could be utilized to regulate power for heating elements intended to deice walkways and stairways on vessels and structures. Similarly it could serve as a warning system to signal the encumbrance of safety and communications equipment. In the aerospace context a miniaturized device could measure and signal the need for mitigating strategies when icing accumulates on components of manned and drone-type aircraft. Details of the RIDE prototype, and miniaturization plans, are presented along with thickness data acquired during two test programs, one study on clear ice layers where measurements were obtained from a distance of ~15 m and the other on foggy ice layers at a distance of approximately 13 m.
