| 英文摘要 | We use the Richardson-Lucy deconvolution algorithm to extract one-dimensional (1D) spectra from Large Sky AreaMulti-Object Fiber Spectroscopic Telescope (LAMOST) spectrum images. Compared with other deconvolution algorithms, this algorithm is much faster. The application on a real LAMOST image illustrates that the 1D spectrum resulting from this method has a higher signal-to-noise ratio and resolution than those extracted by the LAMOST pipeline. Furthermore, our algorithm can effectively suppress the ringings that are often present in the 1D resulting spectra generated by other deconvolution methods. |
