Manual – epc610 Camera Module V1.0 

Time-of-flight camera epc610, 8x8 pixel

General Description

The epc610 Camera Module V1.0 is a fully assembled and tested
3D TOF camera for the evaluation of the epc610 Time of Flight
(TOF) product.
The module includes an epc610 TOF Imager chip, an active IR
LED illumination for the observation area, a complete lens system
and has a cable interface to the mainboard, allowing a flexible and
convenient placement in a lab setup. The module has a 8.7° x 8.7°
optical aperture angle.
In combination with the epc600/610 Evaluation Kit, which provides
all hardware to operate the epc610 Camera Module V1.0, the user
has a fully functional TOF imager evaluation system.
The included comprehensive application software enables the user
to explore the 3D TOF technology as well the epc610 imager chip.

Features

Fully functional TOF camera with 8x8 pixel epc610 Imager chip.

Comprehensive application software with graphical user interface
to operate the epc610 chip inside the camera.

Automatic mode with adaptive integration times.

Manual mode to run the camera in individual set-up or to analyze 
raw data.

Possibility to store and reload operating configurations.

Functionality for logging measurement data on PC.

Purpose

Performance demonstration of the epc610 chip in terms of 
speed, operating range and accuracy.

Demonstration and evaluation hard- and software.

Development system for user's own epc610 chip application.
