Optick is our prototype of a measurement system for measuring glass-to-glass latencies in systems for video processing. The idea for this came from the daily work of our parent company Pengutronix: During development on the Linux graphics stack, the latency from the camera to the screen (camera glass to screen glass) is an important factor. After we have made makeshift setups with various eval-boards in several iterations, the time had now come to professionalize this measuring system a further step.

  • Two measurement channels
  • Communication via LXA IOBus
  • Command-line tool for control and acquisition

Optick measures the time between turning on an LED in front of the DUT's camera and displaying the light on the DUT's screen. The measurements are carried out with a resolution of 21 ns and the accuracy of the crystal oscillator on the device. Optik is controlled via the LXA IOBus. The LXA IOBus uses CAN for communication and is therefore particularly robust in everyday use. A command line tool is available in the LXA IOBus server to control the Optick.

Important: The Optick is a prototype that we want to use ourselves to find out the range of functions such a device actually has to have. But since we're certainly not the only ones who need to measure glass-to-glass latencies, we want to introduce the device here.

Included Accessories

2x LED assembly including cables: The LED assembly with it's four LEDs is placed in front of the DUT's camera.

2x Sensor assembly including cables: Thanks to it's plastic housing the sensor assembly can be directly mounted onto the DUT's display.

Our Commitment to Quality

This device is manufactured in Germany. Each device is put into operation and tested by hand by Linux Automation.
