ESPROS Improves its ToF Evaluation Kit

Espros Photonics presents an improved version of the evaluation kit for its epc610 ToF sensor:

"The new epc610 Evaluation Kit is a significant upgrade from the former version. We opted for a completely new hardware design of the camera module. This module is based on our thorough background on TOF and incorporates the recent learnings from our customers.

A first novelty is an LED subsystem, which is optimized to illuminate the operation range in a more uniform way. Seven LEDs (Osram SFH 4059) are placed at the edge of the camera PCB. These LEDs cover the more distant operating range. Together, they deliver a high intensity, but due to the placement away from the receiver lens, their effect drops drastically at close range. This is where the single short range LED jumps in. Placed close to the receiver lens this single LED is much better suited to delivering light on to close objects, while its effect fades when the targets move further away. The result of this design is an illumination intensity with reduced peaks at certain distances. On signal level, this translates to a lower dynamic range that needs to be covered by the the detector system. Ask your sensor specialist and he will tell you why he likes that! With this design, the epc610 Camera Module works in a range from zero up to about three meters – depending on the target reflectivity."
