Abstract
The invention relates to a static Fourier transform spectrometer which comprises a lens set. Parallel light formed by the lens set directly irradiates on a semi-permeable semi-reflecting lens, the semi-permeable semi-reflecting lens reflects one part of the parallel light on an optical waveguide, the semi-permeable semi-reflecting lens transmits the other part of the parallel light on a holophote, the holophote reflects the other part of the parallel light on the optical waveguide, the two parts of the parallel light form an interference signal in the optical waveguide, and the interference signal is collected by a detector and form an interference map. The static Fourier transform spectrometer can achieve interference of detected light by passing through the semi-permeable semi-reflecting lens for only one time, the utilization rate of light reaches to 100% in theory, mechanical scanning is not needed, speed for collecting light is high, collecting efficiency of light is high, and the static Fourier transform spectrometer is stable in a carrying process and easy to maintain.
