Publication number: 20240319522Abstract: This optical element has a first liquid crystal element LF1 and a second liquid crystal element LF3 that are each able to generate a refractive index distribution of a Fresnel cylindrical lens. The first liquid crystal element LF1 generates a linear focus axis in a first direction, and the second liquid crystal element LF3 generates a linear focus axis in a second direction. The first liquid crystal element LF1 and the second liquid crystal element LF3 are disposed so as to overlap each other such that the first direction and the second direction form an angle so as not to form a substantially perpendicular angle therebetween.Type: ApplicationFiled: June 5, 2024Publication date: September 26, 2024Inventors: Sunri LEE, Giichi SHIBUYA, Hirohiko INA, Hiroto YOSHII
