Abstract: A simple and fast interferometric measurement mainly for applications in thermal IR frequency range is presented. This method makes use of a single detector and a single spatial scan and thus reduces both measuring time and hardware complexity. The principle of operator is frequency coding of one transverse spatial dimension.
