As of today, display performance is a major development criteria in the quest to deliver consumer-ready, high-quality XR glasses. Laser beam scanners in comparison with other display technologies are among the most promising high-dynamic range RGB display engine architectures, e.g., because the size of these devices remains unchanged when increasing the display resolution and field of view. This is in sharp contrast to competing display engines where each pixel constitutes an individual component and these technologies at some point seem to reach their physical limits.
Laser beam scanners (LBS) are among the most promising high-dynamic range, full-color (RGB) display engine architectures. In this paper, we refer to a LBS as a device which redirects one or multiple laser beams in one or two dimensions using micro-electro-mechanical-system (MEMS) mirrors17. Based on a manageable set of features, benchmark scores will be presented that indicate the suitability of LBS relative to two other major XR display technologies, namely Liquid Crystal on Silicon cells (LCoS) and Micro-LED (mLED).

Summary :
LBS in combination with software beam calibration and compensation measures – thereby avoiding large and bulky optics – is one of the most promising small-sized and lightweight display technologies for look-through XR glasses to date.

During Q1 today the commentators mentioned that Ferrari were laser scanning Carlos Sainz car, I think they said it was to check that every component was correctly inserted, is this correct? How is it done? Like is it a handheld gun or does a rig attach to the roof etc?
How accurate would it be? What kind of things can be picked up by this?
Is this something that is done every time they take body panels off? Or is it just that Sainz’s car was damaged previously?
