Title (EN) STRUCTURED LIGHT PROJECTION
(FR) PROJECTION DE LUMIÈRE STRUCTURÉE
Abstract:
(EN) A structured light projection system includes an array of light emitting elements operable, collectively, to emit a regular pattern of light. A first optical element is configured to alter the pattern of light emitted by the array of light emitting elements to generate a first irregular pattern of light, and a second optical element is configured to receive the irregular pattern of light generated by the first optical element and to produce a pattern comprising multiple instances of the first irregular pattern.
(FR) Selon la présente invention, un système de projection de lumière structurée qui comprend un réseau d'éléments électroluminescents utilisables, collectivement, pour émettre un motif régulier de lumière. Un premier élément optique est configuré pour modifier le motif de lumière émis par le réseau d'éléments électroluminescents afin de générer un premier motif irrégulier de lumière, et un second élément optique est configuré pour recevoir le motif irrégulier de lumière générée par le premier élément optique et pour produire un motif comprenant de multiples instances du premier motif irrégulier.
