The cryogenically cooled, optical dew/frost point hygrometer was developed to provide a fast response aircraft instrument for the measurement of very low frost-point temperatures encountered at the higher altitudes. A detailed description of the device is presented, along with a discussion of the laboratory and flight tests performed to date. Problems encountered during the tests are outlined, and recommended changes to the instrument are made for the benefit of those contemplating its use in the future. (Author)
