An indicator device is suitable for a mixed reality device. The indicator device includes a body, a light source unit, at least two positioning elements, a triggering unit and a control unit. The light source unit is disposed on the body and generates a light source. The two elements are disposed separately on the body, wherein the light source unit and the positioning elements are disposed on different axes. The triggering unit is disposed on the body and generates a trigger signal. The control unit is disposed inside the body and is connected to the light source unit and the triggering unit. The control unit receives the trigger signal to generate a first control signal, thereby controlling the light-emitting state of the light source.

According to an exemplary embodiment, an ultrasound apparatus for beamforming with a plane wave transmission may comprise a transceiver connected to a transducer array having at least one transducer element, and at least one processor. The transceiver transmits at least one substantially planar ultrasonic wave into a target region at one or more angles relative to the transducer array, and receives one or more signals responsive from the transducer array. The at least one processor applies a fast Fourier transform (FFT) to the one or more signals from each of the at least one transducer element and calculates at least one frequency within a frequency region, and applies an inverse FFT to at least one produced frequency data.
