Claim Text:
1. A system, comprising: a mobile computing device, wherein the mobile computing device includes an image sensor, a processor, a light source, and a memory that stores program instructions; an optical instrument, comprising: a self-referencing optical module, wherein the self-referencing optical module includes a calibration light source, a shared aperture, a collimator lens, and a diffraction grating to disperse optical output of the calibration light, wherein the dispersed patterns (self-referencing and the external illumination light under test) are separated from each other as formed on the image sensor simultaneously; and a mount for positioning the mobile computing device in a position relative to the self-referencing optical module, wherein in the position the image sensor of the mobile computing device is optically aligned to the output optical path of the self-referencing optical module such that the image sensor receives at least a portion of the dispersed optical output and different wavelength components are received at different locations on the image sensor, wherein the program instructions stored in the memory are executable by the processor to cause the mobile computing device to perform functions, the functions comprising: Using the image sensor to obtain simultaneously the dispersed optical outputs of the self-referencing and the external illumination light under test; and determining a wavelength spectrum of the optical output of the external illumination light under test.
