A method of optical distance and speed measurement related to radar. It involves the emission of laser beams. Sensors then detect the reflected light. The distance is calculated from the travel time of the light.
The encyclopedia explains the major technical terms used to describe the technologies for the future markets of today, tomorrow and beyond. From A as in app to M as in MEMS right through to Z as in ZigBee.
Light field camera
The light field camera’s image sensor detects not only the brightness and colour values but also the many different incidence angles of the light beams. The focal plane can be adjusted to specific objects so as to place some image planes in sharp focus while others are out of focus.
Low Power Wide Area Network
Wireless network for machine-to-machine communication
Long Term Evolution
Successor to LTE. The mobile communications technology enables transfer rates of up to 1 gigabit per second.
