Abstract: An apparatus for processing an optical signal of a spectrometer using sparse nature of a signal spectrum is provided including an optical filter array configured to filter an incident light, an optical sensor array configured to convert the filtered light into charges and a digital signal processing unit configured to perform a digital signal processing on an output from the optical sensor array on the basis of an L1 norm minimization algorithm using sparse nature of a signal spectrum and recover spectrum information of the incident light.
