A system may include an optical source and an adjustable spatial light modulator coupled to the optical source. The system may further include a medium coupled to the adjustable spatial light modulator, and an optical detector coupled to the medium. The optical detector may obtain various optical signals that are transmitted through the medium at various predetermined spatial light modulations using the adjustable spatial light modulator. The system may further include a controller coupled to the optical detector and the adjustable spatial light modulator. The controller may train an electronic model using various synthetic gradients based on the optical signals.

Method and system for machine learning using optical data

The present description relates to a stabilized interferometric system comprising: a light source () for emitting an initial beam of coherent light; a spatial light modulator () configured to receive at least a first part of said initial beam and input data () and configured to emit a spatially modulated beam resulting from a spatial modulation of a parameter of said first part of said initial beam based on said input data; a scattering medium () configured to receive said spatially modulated beam; a detection unit () configured to acquire an interference pattern (IN) resulting from the interferences between randomly scattered optical paths taken by the spatially modulated beam through the scattering material; a control unit () configured to vary the frequency of the laser source in order to at least partially compensate a change in said interference pattern resulting from a change in at least one environmental parameter.

Methods for the stabilization of interferometric systems and interferometric systems implementing such methods

A system may include an optical source and an adjustable spatial light modulator coupled to the optical source. The system may further include a medium coupled to the adjustable spatial light modulator. The system may further include a beam splitter coupled to the optical source and the adjustable spatial light modulator. The beam splitter may generate a first optical signal and a second optical signal using the optical source. The system may further include an optical detector coupled to the beam splitter and the medium. The optical detector may obtain a combined optical signal including a resulting optical signal and the second optical signal. The resulting optical signal may be produced by transmitting the first optical signal through the medium at a predetermined spatial light modulation using the adjustable spatial light modulator.
