Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a projector that accurately measures the temperature of light modulators to perform appropriate control according to the temperature and display an image with good quality.SOLUTION: There is provided a projector comprising: a light source; a plurality of light modulators that modulate light from the light source to form image light; a light combining device that combines the plurality of rays of image light; a projection optical system that projects the light modulated by the light modulators; and temperature measuring parts attached to the light modulators. The light modulators each include a light modulation element, a holding member that holds the light modulation element, and a cover member fixed to one surface of the holding member; the temperature measuring parts each include a sensor body part provided with a sensor element measuring temperature, and the sensor element is in contact with the one surface of the holding member and covered by a cover member from the opposite side of the holding member through a gap.SELECTED DRAWING: Figure 4
【課題】光変調装置の温度を正確に測定することで、温度に応じた適切な制御を行い良質な画像を表示するプロジェクターの提供を目的とする。【解決手段】光源と、光源からの光を変調して画像光を形成する複数の光変調装置と、複数の画像光を合成する光合成装置と、光変調装置により変調された光を投射する投射光学系と、光変調装置に取り付けられた温度測定部と、を備え、光変調装置は、光変調素子と、光変調素子を保持する保持部材と、保持部材の一面側に固定されたカバー部材と、を有し、温度測定部は、温度を測定するセンサー素子が設けられたセンサー本体部を有し、センサー素子は、保持部材の一面に接触するとともに保持部材の反対側から隙間を介してカバー部材に覆われている、プロジェクター。【選択図】図4 |
