Title (EN) OPTICAL ELEMENT AND HEADS-UP DISPLAY
(FR) ÉLÉMENT OPTIQUE ET AFFICHAGE TÊTE HAUTE
(JA) 光学素子、及び、ヘッドアップディスプレイ
Abstract: front page image
(EN)This optical element, which diffuses and outputs incident laser light from a laser light source, can be used, for example, as an optical screen. Said optical element contains a microlens array or a diffraction grating, the pitch of which is set on the basis of the incident numerical aperture and wavelength of the laser light such that the distribution of diffracted light emitted from the optical element is uniform.
(FR)L'invention concerne un élément optique, qui diffuse et délivre une lumière laser incidente provenant d'une source de lumière laser, et peut être utilisé, par exemple, sous la forme d'un écran optique. Ledit élément optique contient un ensemble de microlentilles ou un réseau de diffraction, dont le pas est réglé sur la base de l'ouverture numérique incidente et la longueur d'onde de la lumière laser, de telle sorte que la distribution de lumière diffractée émise par l'élément optique est uniforme.
(JA)光学素子は、例えば光学スクリーンとして使用され、レーザ光源から入射するレーザ光を拡散して出力する。光学素子は、マイクロレンズアレイ又は回折格子を備え、そのピッチは、前記レーザ光の入射開口数及び前記レーザ光の波長に基づき、前記光学素子から射出する回折光の分布が均一となるように設定されている。
