Development of a slitless spectrometer for multispectral flame chemiluminescence

During the master thesis, the image skewing effect in the imaging process of a slitless spectrometer has been explored both theoretically and experimentally, which shows an excellent agreement. It has been found that the image skewing mainly results from the diffraction grating, and this effect is called ananmorphic magnification, which can be totally eliminated by using Littrow configuration of the diffraction grating. By analyzing the spatial distribution of CH (431nm) and C2  (514nm), it has been found that their spatial distributions are slightly different, the reason of which is however left for future research.
