GENERAL OVERVIEW
This document is a manual for the setup and configuration of the
AF0131 Smart iToF depth sensor demo3 evaluation kit, see Figure 1.
Note that this setup concerns the sensor variant without depth
processing on−chip (AF0131 vs AF0130). This has consequences for
the software setup in DevwareX, operating frame rate as well as the
setup of the laser driver board. See specific sections for more details.
The sensor variants AF0130 & AF0131 are pin compatible.
FUNCTIONAL OVERVIEW
The demokit aims to show the performance and features of the
AF0131 Smart iToF depth sensor. DevwareX is the software used to
interface with the hardware over USB and configure the sensor in
different operating modes.
Two modes are currently available for evaluation:
1. Mode 2.2: 1.2 Mp, 15 fps, Single Frequency 100 MHz (range
0.3−1.5 m)
2. Mode 3.2: VGA, 15 fps, Dual Frequency 100 MHz + 120 MHz
(range 0.3−7.5 m)
As development progresses, more evaluation presets and
documentation will become available. Therefore MyON should be
checked regularly for the latest updates on this product. Please do
inform your onsemi representative in case you like to evaluate a mode
that is not yet available.
Please note that the kit has not (yet) been officially certified as eye
safe. However, several safety features have been implemented to
avoid any damage to the user’s eyes, either by wrong configuration or
unexpected single fault failures. The exposure time of the sensor is
limited by the “Laser eye−safety monitoring” feature on the AF0131
sensor, which monitors the modulation of the lasers by the sensor.
Therefore, the lasers will turn off when the exposure time on the
sensor is set too high. On the VCSEL drivers, the over−current
protection and skin safety protection features are enabled and tested
as well.
ATTENTION: The emitted wavelength of the lasers is not visible to
the human eye! We advise the user to exercise caution
and follow the necessary guidelines to protect your
eyes from potential hazards.
