Enhanced Smartphone Spectroscopy via High-throughput Computational Slit

Emily Kuang, Farnoud Kazemzadeh, Alexander Wong


High-performance spectroscopy is often limited by its portability, size, and cost, therefore limiting its reach into various applications that may benefit from it. In this paper, we present a low-cost, low-complexity slitless smartphone-based spectrometer that can be useful for carrying out field studies. Omitting a slit in a spectrometer means loss of spectral resolution in conventional spectrographs; however, we overcome this limitation via the use of a high-throughput computational slit to produce spectra with enhanced spectral resolution and enhanced signal-to-noise characteristics.
