Paper Abstract

In order to fulfill the need of high astronomical observation spectral resolution, we are developing a new stationary interferometric spectrometer: heterodyne holographic spectrometer (HHS). It utilizes the configuration of a Twyman- Green interferometer with two arms adjusted for zero path difference and with a plane diffraction grating replacing one of the arm mirrors. So, it combines the multi-advantages of traditional spectrometers: SGS and FTS (slit grating spectrometer and Fourier transform spectrometer), and avoids their disadvantages, especially in the observation with telescope. We get its experimental result in the laboratory and have a simple discussion on its application prospect in astronomy.
