The enclosed chassis is essential for maintaining high precision and repeatability. It protects the structured light sensors from ambient light interference, which is critical for achieving sub-pixel accuracy during the projection of light stripes.

Monochrome cameras capture grayscale images with superior contrast, which is fundamental for the structured light algorithms to precisely detect the edges of light stripes. This avoids the information loss typically associated with RGB channels in color sensors.

White light allows the system to fully utilize all RGB channels of the sensor, resulting in more intense illumination and higher contrast. This improves the definition of the light stripes and overall scan precision compared to blue light, which often provides lower brightness.
