1. A system comprising:
an image sensor comprising a pixel array that detects electromagnetic radiation;
an emitter that cycles a plurality of electromagnetic sources, wherein the plurality of electromagnetic sources comprises:
a visible source that emits a visible wavelength of electromagnetic radiation; and
one or more spectral sources tuned to emit one or more spectral wavelengths of electromagnetic radiation selected to elicit a spectral response from a tissue; and
a controller in electronic communication with the image sensor and the emitter, wherein the controller synchronizes operations of the image sensor and operations of the emitter;
wherein the image sensor senses reflected electromagnetic radiation emitted by the emitter and outputs data, such that:
the image sensor generates a visible exposure frame in response to detecting the visible wavelength of electromagnetic radiation, and
the image sensor generates a plurality of spectral exposure frames comprising spectral response data based on a plurality of spectral responses in response to detecting pulses of the one or more spectral wavelengths of electromagnetic radiation, and
wherein the spectral exposure frame does not comprise observable speckle pattern;
wherein the controller processes one or more of the plurality of spectral exposure frames to generate a spectral datastore comprising the spectral response data;
wherein the controller provides the spectral datastore to a corresponding system that determines a classification of a malady, a biological process, or a type of tissue based on the spectral datastore;
wherein the system receives the classification from the corresponding system.
