    Abstract: Disclosed herein are wearable devices, their configurations, and methods of operation that use self-mixing interferometry signals of a self-mixing interferometry sensor to recognize user inputs. The user inputs may include voiced commands or silent gesture commands. The devices may be wearable on the user's head, with the self-mixing interferometry sensor configured to direct a beam of light toward a location on the user's head. Skin deformations or vibrations at the location may be caused by the user's speech or the user's silent gestures and recognized using the self-mixing interferometry signal. The self-mixing interferometry signals may be used for bioauthentication and/or audio conditioning of received sound or voice inputs to a microphone.

    Abstract: Methods and systems concerning non-reciprocal sensing paths for a self-mixing interferometry operation are disclosed herein. Optical components may be used to direct light transmit from a light source along an illumination path. The optical components may additionally return light to the light source after being reflected from a target and may direct the returned light along a collection path. The illumination path and the collection path may be at least partially non-reciprocal so that the transmitted light and the returned light follow along partially different paths. Once the received light is received within a cavity of the light source, a self-mixing interferometry operation may be performed and may be used to detect a property of the target in relation to the light source.

    Abstract: A system may include one or more finger devices that gather input from a user's fingers. The system may include control circuitry that sends control signals to an electronic device based on the input gathered with the finger devices. A finger device may include one or more proximity sensors that measure a distance to the user's finger. The proximity sensor may be a self-mixing optical proximity sensor having a laser and photodiode. The proximity sensor may have submicron resolution and may be configured to detect very small movements of the finger as finger pad is moved around by a thumb finger, by a surface, and/or by other finger movements. The proximity sensor may measure changes in distance between the proximity sensor and a flexible membrane that rests against a side portion of the user's finger.
