Abstract: Embodiments of the present disclosure provide an interface interaction method and apparatus, an electronic device, and a storage medium. The method includes: displaying a target interface, where at least one interface object is displayed on the target interface, and the interface object includes an interface display resource and/or an interface display control; acquiring, in response to an object trigger operation being input on an interface object, the triggered interface object as a target object; and determining voice introduction information corresponding to the target object and playing the voice introduction information.

Abstract: According to one aspect, a coherent lidar system such as a Frequency-Modulated Continuous Wave (FMCW) lidar system may be provided with a beam steering or scanning arrangement which provides three-dimensional scanning. By providing a beam steering or scanning arrangement which provides an approximately 360 degree range of horizontal scanning, and an approximately twenty degree range of vertical scanning, an FMCW lidar system may achieve a scanning field of view that is similar to that of Time-of-Flight (TOF) lidar systems. A FMCW lidar system with three-dimensional scanning may enable fewer FMCW lidar systems to be used to provide a desired overall scanning field of view, and also achieve a comparable overall scanning field of view as a TOF lidar system substantially without issues such as the significant movement of electrical components.

Abstract: The technology described in this document can be used to implement an optical device for producing optical pulses that includes an optical oscillator including at least one optical arm including at least one piece of fiber and at least one optical filter, a starting arm coupled to the at least one optical arm to generate spikes of radiation for the optical oscillator to start pulsation, and an optical switch coupled between the optical oscillator and the starting arm to connect the starting arm to the at least one optical arm to start the optical oscillator using the spikes of radiation generated by the starting arm.
