- Abstract
We developed two types of liquid-crystal spatial light modulators: an improved device by modifying each layer of the device and a large active area for industrial infrared lasers to demonstrate innovative manufacturing and fabrication techniques in smart manufacturing. The reconstruction of computer-generated holograms was demonstrated to prove the concept of the proposed device in the IR region. The incident phase performance characteristics of the device under high-power laser irradiation were obtained using a 1030 nm ultrashort pulse laser.
