| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a sensor system which more accurately detects an operation by a person to aerial videos, by preventing light reflected on a half mirror from an object to be projected from being made incident on a sensor.SOLUTION: A sensor system 1 comprises: a projection optical system which forms a real image of an object to be projected in the air as an aerial image 120, by an image 110 displayed on a display surface of a display 10 as the object to be projected having an illuminant, at least one half mirror 20, and a retroreflective sheet 30; a sensor 40 which detects light of light-emission wavelength of the display from a predetermined region including the aerial image; and a light shielding member 60 which is arranged on a light path in which the light of the display is reflected on the half mirror one time to be injected into the sensor.SELECTED DRAWING: Figure 2
【課題】被投影物がハーフミラーにて反射した光がセンサへ入射するのを防ぎ、空中映像に対する人の操作をより高精度に検知するセンサシステムを提供する。【解決手段】センサシステム１は、発光体を有する被投影物としてディスプレイ１０の表示面に表示される画像１１０と、少なくとも１つのハーフミラー２０と、再帰反射シート３０とにより被投影物の実像を空中に空中像１２０として結像する投影光学系と、空中像を含む所定の領域からのディスプレイの発光波長の光を検知するセンサ４０と、ディスプレイの光がハーフミラーで１回反射してセンサに入射する光路に配置された遮光部材６０と、を備える。【選択図】図２ |
