Compact transform spectrometer based on sampling a standing wave |
摘要 |
A spectrometer for determining a spectrum of a light by using a mirror to reflect the light so that the light forms an intensity standing wave pattern through superposition of an incident portion of the light and a reflected portion of the light. The spectrometer is equipped with an intensity detector whose thickness is less than a shortest wavelength of the light being examined and which is semitransparent over the spectrum. The spectrometer has a mechanism to provide relative movement between the mirror and the intensity detector such that the intensity detector registers a variation of the intensity standing wave pattern. An analyzer, such as a Fourier transform analyzer, is employed to determine the spectrum of the light from that variation of the intensity standing wave pattern. |
