Title (EN) BEAM-SCANNING DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE À BALAYAGE DE FAISCEAU
(JA) ビーム走査型表示装置
Abstract:
(EN) A scanning image display device comprises: a light source unit for emitting a laser beam; a scanning mirror for two-dimensionally scanning the laser beam in a first direction and a second direction intersecting the first direction; and a control unit for controlling the driving of the scanning mirror. The control unit drives the scanning mirror so that the scanning frequency in the first direction becomes higher than the scanning frequency in the second direction, and changes the scanning amplitude in the first direction by changing the scanning frequency in the first direction in synchronization with the cycle of the scanning frequency in the second direction.
(FR) La présente invention concerne un dispositif d'affichage d'image par balayage, comprenant : une unité de source lumineuse pour émettre un faisceau laser ; un miroir de balayage pour un balayage en deux dimensions du faisceau laser selon une première direction et une seconde direction recoupant la première direction ; et une unité de contrôle pour contrôler le pilotage du miroir de balayage. L'unité de contrôle commande le miroir de balayage de façon à ce que la fréquence de balayage dans la première direction devienne plus élevée que la fréquence de balayage dans la seconde direction, et change l'amplitude de balayage dans la première direction en changeant la fréquence de balayage dans la première direction en synchronisation avec le cycle de la fréquence de balayage dans la seconde direction.
(JA)  走査型画像表示装置は、レーザビームを出射する光源部と、前記レーザビームを第1方向及び前記第1方向と交差する第2方向に2次元走査する走査ミラーと、前記走査ミラーの駆動を制御する制御部とを含み、前記制御部は、前記第1方向の走査周波数が前記第2方向の走査周波数よりも高い周波数となるように前記走査ミラーを駆動するとともに、前記第2方向の走査周波数の周期に同期させて前記第1方向の走査周波数を変化させることにより前記第1方向の走査振幅を変化させる。
