General Description

The epc600 Camera Spot is a fully assembled and tested TOF
Range Finder camera to be used with the epc600/610 Evaluation
Kit.
The module includes an epc600 TOF Range Finder chip, an active
IR LED illumination for the observation area, a complete lens sys-
tem and a cable interface to the mainboard. This allows for a flexi-
ble and convenient placement in a lab setup. The module has a
1.4° x 1.4° optical aperture angle.
In combination with the epc600/610 Evaluation Kit (which provides
all hardware to operate the epc600 Range Finder module), the
user has a fully functional TOF evaluation system.
The included application software enables the user to explore the
TOF Range Finder technology as well the epc600 Range Finder
chip.

This will set the evaluation system into the epc600 evaluation mode and al- lows for the operation through the application software on the computer. Connect with the USB cable the computer to the Evaluation Board. The board is now powered up by USB.

  • Page 14: Software "Epc600 Evaluation System" And User Interface

    This chapter describes the epc600/610 Evaluation Kit software (SW) and graphical user interface (GUI). The user interface is designed as a dialog based application. The software operates the epc600 camera module, reads the data delivered by the module and allows for data logging.

    Area Description Distance & Amplitude Shows the measured distance and amplitude. Real time values as well as statistical figures are displayed. dialog Integration time dialog The dialog holds the switch that allows for either the setting of the the integration time manually or to have the internal algorithm automatically set the integration time.

  • Page 16: Distance And Amplitude Dialog

    1.6μs / 12.5μs / 205μs. The integration time corresponding to the selected values is displayed in real time and is continuously adjust - ed to get the optimal measurement result. Refer to the epc600 datasheet for more information on integration time and how to adjust it.

  • Page 17: Distance Range Settings

    5.1.5. Distance range settings The settings here affect only the user interface and do not have any influence on the epc600 chip. They are intended to set a fixed offset value and “zoom” in on an operational point. The “zoom” effect will become visible on the range bar of the distance and amplitude dialog.
