3D Image Sensors Evaluate Size, Shape and Level

The Photonic Mixing Device (PMD) principle is based on Time of Flight (TOF) distance measurement.

3D Image Sensor Uses Reliable Time of Flight Distance Measurement
The Photonic Mixing Device (PMD) principle is based on Time of Flight (TOF) 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.

  • Evaluates size, shape and level in material handling applications
  • Compact sensor uses time-of-flight distance measurement and photonic mixer device technology to identify an object in the sensor‘s field of view
  • Integrated 64 x 48 pixel array – in which each pixel represents a time of flight measurement – defines the field of view for the sensor
  • Designed for applications such as palletzing and de-palletizing, material handling, bulk level of materials and intelligent routing/sorting
