Abstract
(EN)
An electronically scanning emitter array that includes a two-dimensional array of light emitters arranged in k emitter banks. Each of the k emitter banks can include a subset of the light emitters in the two-dimensional array and can be independently operable to emit light from its subset of emitters. The electronically scanning emitter array can further include first and second capacitor banks coupled to provide energy to the two-dimensional array of light emitters and emitter array driving circuitry coupled to the first and second capacitor banks and to the k emitter banks. Each of the first and second capacitor banks can include at least one capacitor. The emitter array driving circuitry can include a first high-side switch coupled between the first capacitor bank and a voltage source, a second high-side switch coupled between the second capacitor bank and the voltage source, and k/2 low-side switches coupled between the k emitter banks and ground; and the emitter driving circuitry can be configured to fire one emitter bank in the k emitter banks at a time according to a firing sequence until each of the k emitter banks are fired.

L'invention concerne un réseau d'émetteurs à balayage électronique comprenant un réseau bidimensionnel d'émetteurs de lumière disposés dans k blocs d'émetteurs. Chacun des k blocs d'émetteurs peut comprendre un sous-ensemble des émetteurs de lumière dans le réseau bidimensionnel et peut fonctionner indépendamment afin d'émettre de la lumière à partir de son sous-ensemble d'émetteurs. Le réseau d'émetteurs à balayage électronique peut en outre comprendre des premier et second blocs de condensateurs couplés pour fournir de l'énergie au réseau bidimensionnel d'émetteurs de lumière et des circuits d'attaque de réseau d'émetteurs couplés aux premier et second blocs de condensateurs et aux k blocs d'émetteurs. Chacun des premier et second blocs de condensateurs peut comprendre au moins un condensateur. Le circuit d'attaque de réseau d'émetteurs peut comprendre un premier commutateur côté haut couplé entre le premier bloc de condensateurs et une source de tension, un second commutateur côté haut couplé entre le second bloc de condensateurs et la source de tension, et k/2 commutateurs côté bas couplés entre les k blocs d'émetteur et la terre; et le circuit d'attaque d'émetteur peut être conçu pour lancer un bloc d'émetteurs parmi les k blocs d'émetteurs à un instant en fonction d'une séquence de lancement jusqu'à ce que chacun des k blocs d'émetteurs soit déclenché.
