Abstract
An electronic device such as a portable electronic device may include a single-shot alignment-free spectrometer with no moving parts. The spectrometer may include a diffractive member, such as a grating, an aperture, and an image sensor that generates data in response to incident light. The diffractive member may diffract the incident light based on its wavelength and angle of incidence, and the aperture may further encode the light. The data generated by the image sensor may be used by control circuitry in combination with correlations between spectrometer measurements and known light profiles to determine the wavelength and angle of incidence of the light. These correlations may be determined using a deep neural network. Control circuitry may adjust one or more settings of the electronic device based on the wavelength and angle of incidence, or may use the wavelength and angle of incidence to determine information regarding an external object.
