An emitter assembly and waveform sensor assembly for visualizing a target is disclosed. The emitter assembly is configured to emit electromagnetic radiation and includes a first emitter configured to emit at least one of visible light, infrared radiation, or a combination thereof and a second emitter configured to emit structured electromagnetic radiation. The waveform sensor assembly is configured to detect the electromagnetic radiation emitted by the emitter assembly and obtain three-dimensional images corresponding to the detected electromagnetic radiation.
