The design of 2D eye-box expanded volume holographic waveguide with wide field of view for AR application
Wan Lin Li;Zi Fan Chen;Shiuan Huei Lin;Vera Marinova;Ken Y. Hsu
In this paper, we demonstrate design and operation principle of holographic waveguide by using holographic optical element (HOEs). The preliminary optical experiments have been performed to demonstrate our recursive inference. Then, we propose a novel optical scheme to increase FOV of a VHOE-based waveguide with 2D eye-box expansion.

Photo-aligned liquid crystal cell with PAZO azo-polymer for writing geometrical phase hologram
Minh Chau Nguyen Hong;Shiuan Huei Lin;Vera Marinova;Ken Yu Hsu
We demonstrate fabrication of the photo-aligned liquid crystal cell using poly[1- [4-(3-carboxy-4-hydroxyphenylazo)benzenesulfonamido]-1,2-ethanediyl, sodium salt] (PAZO) azo-polymer and its application for writing a geometrical phase hologram (GPH).

Optical Scanning Holography without Interference
Chen-Ming Tsai;Jung-Ping Liu
In optical scanning holography (OSH), the interference fringe used for scanning the
object is generated by a two-pupil interferometer. However, this interference system is
sensitive to the environmental fluctuation. Here we proposed a new OSH technique without
interference to minimize environmental fluctuation.

Volume Holographic Optical Illuminator for Multifocal Confocal Microscopy
Surag Suresh;Sunil Vyas;J Andrew Yeh;Yuan Luo
To reduce the scanning time, a multifocal confocal microscopy system is designed and developed. By incorporating photopolymer (PQ-PMMA) based volume holographic optical element in the illumination path multifocal spots are generated. Uniformity of each focal spot is achieved by utilizing super Gaussian (SG) beam. Replacing pinhole-detector pair with CCD camera made the system design more simple.

Applying dynamic structured light for object recognition and depth sensing
Hsiao-Yun Hsu;Ying-Kai Hong
High phase accuracy and fast response LCoS panel was applied for pattern recognition and depth sensing with a one-camera optical system. The various focusing distance of the near-infrared structured light can be generated by corresponding CGHs and captured by CCD camera. The captured images were sent to pre-trained model for pattern recognition and interpolation object distance from database. The predict distance error is less than +-2.10 cm in the range between 40 to 200 cm.

Digital Optical Phase Conjugation Display Using Lens-Array as its Screen
Yu-Hong Huang;Zi-Hong Lin;Yeh-Wei Yu;Ching-Cherng Sun;Tsung-Hsun Yang
This paper mainly describes the generation of naked-eye 3D images with a well-designed digital optical phase conjugate system (DOPC). We compare the point light source reconstruction of a single-lens with the lens-array system, and then introduce the generation of the three-dimensional image with the proposed DOPC display.
