| Abstract: | The Volume Phase Holographic Grating(VPHG) is applied to astronomy in recent years,owe to its characteristic advantages.For instance,it can gain large grating, high diffraction efficiency,close to 100%,super blazing,etc.The large scientific project -LAMOST(Large Sky Area Multi-Object Fiber Spectroscopic Telescope),can acquire the spectra of 4000 goals from distance objects.In order to improve the transmission efficiency maximally,the VPHG is equipped as a disperse element.It is the first application in dome... |
