Abstract
A display apparatus configured to be coupled to a movable object includes at least a first laser sensor module and a display device configured to display a field-of-view. The first laser sensor module is configured to determine, by self mixing interference measurements, movements of the movable object with respect to a reference object mechanically coupled to the movable object. The first laser sensor module is configured to emit at least three measurement beams in three different spatial directions to the reference object when the display apparatus is coupled to the movable object and the first laser sensor module is configured to determine velocity vectors or distances collinear to the spatial directions. The display device is configured to integrate at least one virtual object in the field-of-view in accordance with the determined movements of the movable object.
