| description | A liquid crystal shutter (110) uses a first liquid crystal material and controls irradiation of light onto a prescribed location according to a supplied drive waveform. A LCOS (120) uses a second liquid crystal material different from the first liquid crystal material and modulates light according to a supplied drive waveform. A supply unit (130) supplies the drive waveforms to the liquid crystal shutter (110) and LCOS (120) and adjusts the waveforms so that the contrasts of the liquid crystal shutter (110) and LCOS (120) are each at least 50% of the maximum contrast at the same temperature.
L'invention porte sur un obturateur à cristaux liquides (110) qui utilise un premier matériau de cristal liquide et qui commande le rayonnement de lumière sur un emplacement prescrit en fonction d'une forme d'onde d'attaque fournie. Un cristal liquide sur silicium (120) utilise un second matériau de cristal liquide différent du premier matériau de cristal liquide, et module une lumière en fonction d'une forme d'onde d'attaque fournie. Une unité d'alimentation (130) fournit une forme d'onde d'attaque à l'obturateur à cristaux liquides (110) et au cristal liquide sur silicium (120), et ajuste les formes d'onde de telle sorte que les contrastes de l'obturateur à cristaux liquides (110) et du cristal liquide sur silicium sont chacun d'au moins 50 % du contraste maximal à la même température.
液晶シャッタ（１１０）は、第１液晶材料を用いた液晶シャッタであって、供給される駆動波形に応じて光の所定箇所への照射を制御する。ＬＣＯＳ（１２０）は、第１液晶材料と異なる第２液晶材料を用いたＬＣＯＳであって、供給される駆動波形に応じて光を変調する。供給部（１３０）は、液晶シャッタ（１１０）およびＬＣＯＳ（１２０）のコントラストがそれぞれ同一の温度で最大コントラストの５０％以上となるように調整した各駆動波形をそれぞれ液晶シャッタ（１１０）およびＬＣＯＳ（１２０）に供給する。 |
