    Abstract: The present invention concerns a method and an apparatus for controlling a MEMS micro-mirror device. The invention enables the control of the micro-mirror deflection angle and of the micro-mirror scanning frequency, essential for the projection as it relates directly to the size of the projected image. The MEMS micro-mirror device has a fixed part (102) and a micro-mirror (100) that can oscillate along at least one oscillation axis, a magnet (200) either placed next to said fixed part (102) or on the said movable part (100) and a sensing coil (202) placed on said moving part (100) or on said fixed part (102). A detecting circuit detects at least one value (Uιnd) of the inducted voltage in said sensing coil (202) for each period and for each oscillation axis, and a calculating circuit (404) calculates the amplitude of the movement of said micro-mirror (100) by means of said value (Umd)- Another independent electrical drive coil can be used in order to have two independent electrical coils respectively for driving the micro- mirror and for sensing its positions. The invention can prevent an unexpected default of the projection system.

    Abstract: La présente invention concerne un procédé pour actionner une structure résonante dans un microsystème électromécanique. La fréquence de résonance de la structure résonante mécanique peut se varier entre une fréquence de résonance minimale et une fréquence de résonance maximale définissant une bande de fréquence de résonance. Le procédé comprend: la génération (21) d'un premier signal d'actionnement périodique à une première fréquence; la génération (23) d'un deuxième signal d'actionnement périodique à une deuxième fréquence; le sélection (25) du premier signal d'actionnement et/ou du deuxième signal d'actionnement; et l'application (31) successivement du premier signal d'actionnement et du deuxième signal d'actionnement ou simultanément d'une combinaison du premier signal d'actionnement et du deuxième signal d'actionnement à la structure résonante pour faire osciller la structure résonante à sa fréquence de résonance. La première fréquence se trouve au-dessous de la bande de fréquence de résonance alors que la deuxième fréquence se trouve au-dessus de la bande de fréquence de résonance. De cette manière on peut faire osciller la structure résonante à sa fréquence de résonance.

    Abstract: The present invention provides a projection system (10), preferably for a head-up display e.g. on board a vehicle, comprising a laser source (1), a diffuser (3) and telecentric optics (2) disposed between the laser and the diffuser so that the telecentric optics outputs parallel rays to the diffuser, the diffused light being thus independent from the incidence angle; each pixel of the projected image has the same brightness, regardless of the angle or of the position from which it is viewed.
