Abstract:
L'invention concerne un procédé de pilotage d'un afficheur tête-haute (10) pour véhicule automobile (V) qui comprend une unité de génération d'images (12) adaptée à émettre un faisceau lumineux transportant des images (Img), et une unité d'atténuation (14) de l'intensité lumineuse dudit faisceau lumineux, ledit procédé de pilotage comprenant : - une étape d'élaboration d'une consigne de pilotage d'une source de lumière (12A) de l'unité de génération d'images, - une étape d'élaboration d'une consigne de pilotage de l'unité d'atténuation, et - une étape de pilotage de ladite source de lumière et de ladite unité d'atténuation selon les deux consignes de pilotage. dans lequel la consigne de pilotage de l'unité d'atténuation est élaborée selon le positionnement d'un paramètre relatif à l'intensité lumineuse dudit faisceau lumineux par rapport à une valeur seuil.
Abstract:
Methods of forming polarized panes for variable transmission windows are disclosed. The polarized panes are formed from transparent substrates that are brushed with a brushing pattern that varies continuously in a select direction over each of one or more periods. A layer of polarizable material such as POLARCOAT material can be deposited on and responds to the brushed surface by forming a polarization pattern that substantially matches the brushing pattern and thus also includes one or more periods.

본 발명은 반사 방지용 편광판 및 이를 포함하는 화상표시장치에 관한 것으로서, 보다 상세하게는, 편광자 및 상기 편광자의 하부에 위치한 사분파장 필름층(QWP)과 +C 플레이트층을 포함하며, 상기 편광자, 사분파장 필름층 및 +C 플레이트층의 전체 굴절률비(Nz)는 0.1 내지 0.8임으로써, 화면의 정면 방향에서뿐만 아니라 경사 방향에서도 반사 방지 특성이 우수한 편광판 및 이를 포함하는 화상표시장치에 관한 것이다.
Abstract:
The disclosure is directed to an element that is capable of acting as both an optical polarizer and an optical attenuator, thus integrating both functions into a single element. The element comprises a monolithic or one piece glass polarizer (herein also call the "substrate"), a multilayer " light attenuation or light attenuating " ("LA") coating that has been optimized for use at selected wavelengths and attenuations deposited on at least one polarizer facial surface, and a multilayer anti-reflective (AR) coating on top of the LA coating. The disclosure is further directed to an integrated optical isolator/attenuator comprising a first and a second polarizing elements and a Faraday rotator for rotating light positioned after the first polarizing element and before the second polarizing element, the integrated optical isolator/attenuator both polarizing and attenuation a light beam from a light source.
Abstract:
A patterned retarder is described that may be used with a laser source array to obtain a combined beam suitable for three-dimensional laser image projection using orthogonal polarization states and/or orthogonal color spaces.
