Applications
ToF illumination and 3D measurement
Use DMP300KP as the illumination component in a ToF transmitter. Its wavelength, pulsed output and divergence help define the emitter side of a depth-sensing, 3D-scanning or volume-measurement design. Pair the transmitter with the receiver and processing architecture selected for your measurement task.
Spatial interaction and scene sensing
Pulsed illumination can support sensing systems for gesture interaction, AR/VR, people-flow measurement and obstacle observation. The emitter’s compact package supports layouts where the driver, optics and sensing hardware share limited installation space.
