Realtime 3D imaging via time of flight

IFM introduces a new 3D Image Sensor that evaluates size, shape and level in material handling applications. The compact sensor uses time-of-flight distance measurement and photonic mixer device technology to identify an object in the sensor‘s field of view. An integrated 64 x 48 pixel array – in which each pixel represents a time of flight measurement – defines the field of view for the sensor.

The 3D sensor technology provides critical information in applications such as palletzing and de-palletizing, material handling, bulk level of materials and intelligent routing/sorting.


Technology
3D Image Sensor Uses Reliable Time of Flight Distance Measurement
In its most simple version, a light pulse is radiated from the sensor. This pulse is reflected by an object and detected by the sensor's smart pixel receiver element. A comparison between the optical and electrical reference signals yields an output signal that carries the desired distance information.

Robust, compact design for industrial applications
The solid-state, robust metal housing measures only 42 x 62 x 42 mm and is designed to withstand harsh environments and to perform in fast-moving applications. Application parameters are quickly established with the sensor’s Setup Wizard software that can be used with a PC. The Setup Wizard guides the user in a few steps to configure the application. The sensor can provide either digital or analog outputs.
