Title (EN) FRESNEL LENS, SCREEN, IMAGE DISPLAY DEVICE, LENS MOLD MANUFACTURING METHOD, AND LENS MANUFACTURING METHOD
(FR) LENTILLE DE FRESNEL. ECRAN, DISPOSITIF D'AFFICHAGE D'IMAGES, PROCEDE DE FABRICATION D'UN MOULE DE LENTILLE, ET PROCEDE DE FABRICATION D'UNE LENTILLE
Abstract: front page image
(EN)A Fresnel lens has a pitch including a hybrid prism comprising a refraction prism unit (3A) for emitting an incident light (li1) of an incident angle (a) as an outgoing light (lo1) of an outgoing angle (f) by two refractions, and a total reflection prism unit (4A) for emitting an incident light (li2) of an incident angle (a) as an outgoing light (lo2) parallel to the outgoing light (lo1) by a refraction, a total reflection and a refraction.
(FR)L'invention concerne une lentille de Fresnel comprenant un pas contenant un prisme hybride présentant une section de prisme de réfraction (3A) conçue pour émettre une lumière incidente (li1) présentant un angle d'incidence (a) et une lumière sortante (lo1) présentant un angle d'incidence (f) de deux réfractions; et une section de prisme de réflexion totale (4A) conçue pour émettre une lumière incidente (li2) présentant un angle d'incidence (a) et une lumière sortante (lo2) parallèle à la lumière sortante (lo1) d'une réfraction, d'une réflexion totale et d'une réfraction totale.
