Abstract: A tunable acoustic gradient index of refraction (TAG) lens and system are provided that permit, in one aspect, dynamic selection of the lens output, including dynamic focusing and imaging. The system may include a TAG lens and at least one of a source and a detector of electromagnetic radiation. A controller may be provided in electrical communication with the lens and at least one of the source and detector and may be configured to provide a driving signal to control the index of refraction and to provide a synchronizing signal to time at least one of the source and the detector relative to the driving signal. Thus, the controller is able to specify that the source irradiates the lens (or detector detects the lens output) when a desired refractive index distribution is present within the lens, e.g. when a desired lens output is present.

Abstract: A beam steering device includes a housing and a transceiver that emits and receives light beams through at least one opening in the housing. A rotator includes a cylindrical body rotatably mounted within the housing axially between the transceiver and the at least one opening. A wedge-shaped prism is secured within the body and includes a first surface extending perpendicular to the axis and a second surface extending transverse to the axis. An encoder member and a drive member are provided on an outer surface of the body. Sensors are mounted to the housing to sense the encoder member and provide an encoder signal indicative of a rotational position of the prism about the axis. At least one drive element is mounted to the housing and applies force to the drive member to rotate the body and prism about the axis for steering light beams propagating through the prism.

Abstract: A phase modulator with reduced Residual Amplitude Modulation includes a main path; a correction path; a first coupler configured to split, at a first ratio, an input to the main path and the correction path; and a second coupler configured to combine outputs from the main path and the correction path and to split the combined outputs, at a second ratio, with a first output comprising an output of the phase modulator with the reduced Residual Amplitude Modulation. The correction path can include a correction signal with a proper amplitude and phase that, when combined with an output signal from the main path by the second coupler, cancels the Residual Amplitude Modulation from the output signal.
