Why do I need a back wall?

The Styku scanner should be set up with a wall behind the rotating platform. This helps the scanner find the edges of the body, and produces more consistent scans.

A back wall provides a way for the infrared light to return back to the scanner. The infrared light hits the back wall and bounces back. This provides a sharper image and will provide more accurate and precise measurements.

If there is no back wall, the image will not be as sharp and you'll notice a bit of "fuzziness" in the scan or artifacts, particularly between the thighs. The measurements will also be larger than expected.

The wall should be 2-5 feet away from the rotating platform (55-150cm).
