ESPROS Time-of-Flight Imaging

ESPROS Photonics enables Range Finding solutions based on the principle of Time of Flight (TOF). The solutions excel in applications requiring ranging distances from approximately 20 cm to 10 m.

ESPROS offers a range of TOF Imager Chips and Modules including 1x1, 8x8, 160x60 and 320x240 pixel array formats. ESPROS' unique technology offers both photonics and mixed signal circuitry on one chip, giving outstanding optical detector performance.

TOF RANGE 600

The TOFRANGE 600 is a industrial range finder based on the the time-of-flight principle. It measures the distance to an object by the time it takes for a pulse of light to travel to an object and back to the sensor. In order to do this, the sensor is equipped with a LED light source, high frequency electronics and a very light sensitive chip sensor. This detection principle is very power efficient and allows measurements at a high rate. The robust, light weight and cost effective design of TOFRANGE 600 allows it to be used in many industrial indoor and outdoor applications.

TOF CAM 635

The TOFCAM 635 is a new design of a miniaturized and cost optimized 3D camera able to take and process more than 10 HDR depth images per second in full resolution, compensated against ambient light, temperature and reflectivity of the scene. The system can work under full sunlight conditions, and outputs depth and greyscale images, enabling a direct jump into the latest technology of 3D depth sensing. All the complicated tasks around optics, illumination and signal processing are already solved.
