A mobile computing device that includes an image sensor may be used to detect the result of a biomolecular assay. The biomolecular assay may be performed in an optical assay medium that provides an optical output in response to light from a light source, with the optical output indicating result. A wavelength-dispersive element may be used to disperse the optical output into spatially-separated wavelength components. The mobile computing device may be positioned relative to the wavelength-dispersive element such that different wavelength components are received at different locations on the image sensor. With the mobile computing device positioned in this way, the image sensor may be used to obtain one or more images that include the separated wavelength components of the optical output. A wavelength spectrum of the optical output may be determined from the one or more images, and the result may be determined from the wavelength spectrum.
