This paper presents a novel method for using programmable graphics hardware to generate fringe patterns for SLM-based holographic displays. The algorithm is designed to take the programming constraints imposed by the graphics hardware pipeline model into consideration, and scales linearly with the number of object points. In contrast to previous methods we do not have to use the Fresnel approxi...

We suggest a method for coding high resolution computer—generated volume holograms. It involves splitting the computer—generated hologram into multiple holograms, each individually recorded as a volume hologram utilizing the maximal resolution available from the spatial light modulator. Our method enables their simultaneous subsequent reconstruction. We demonstrate the recording and the reconst...

We report what we believe to be the first realization of a computer-generated complex-valued hologram recorded in a single film of photoactive polymer. Complex-valued holograms give rise to a diffracted optical field with control over its amplitude and phase. The holograms are generated by a one-step direct laser writing process in which a spatial light modulator (SLM) is imaged onto a polymer ...

Holography has emerged as one of the most attractive three-dimensional display technologies. With technological development computer science and coherent light source, computer-generated holography been applied in many fields. However, speckle noise holographic reconstructed image seriously affects viewing experience. In this paper, cause generation is introduced. Then, discussions about suppre...

We describe various techniques to synthesize three types of computer-generated hologram (CGH): the Fresnel-Fourier CGH, the Fresnel CGH, and the image CGH. These holograms are synthesized by fusing multiple perspective views of a computer-generated scene. An initial hologram is generated in the computer as a Fourier hologram. Then it can be converted to either a Fresnel or an image hologram by ...

We have investigated the image type full-color computer-generated hologram that has full parallax and can be reconstructed with three color LEDs. The object of the hologram is processed from 3D computer graphics polygon data and has shaded surface with hidden surface removal. The optical reconstructed image from the printed hologram is evaluated. © 2011 Optical Society of America OCIS codes: 09...

This study compared the efficacy of a job knowledge test in predicting task performance and examined the mediating effect of job knowledge in the cognitive ability-performance relationship. Two hundred undergraduates completed a test of cognitive ability and a written job knowledge test, and then performed a computer-generated truck dispatching simulation. Results demonstrated that job knowledg...

Health, particularly diet and everyday nutrition, as the ultimate causal factor in life is an important aspect of every child’s education. Meanwhile, computer generated (CG) 3dimensional (3-D) graphics is a medium often used by entertainment and advertising. Educational intervention to help children make appropriate dietary choices can be designed by employing similar methods used by entertainm...

Results Forty representative S. Typhi strains belonged to 4 sequence types (ST1, ST2, ST890, and ST892). The predominant S. Typhi genotype (31/40) was ST2 and it had a diverse geographic distribution. We discovered two novel STs – ST890 and ST892. M-CGH showed that 69 genes in these two novel STs were divergent from S. Typhi Ty2, which belongs to ST1. In addition, 5 representative Typhi strains...

Complex dynamic events are often misunderstood at the perceptual and intuitive level. In spite of these difficulties, experts, such as athletes or billiard players, learn to make very precise dynamic judgments. This study explored the basis of such judgmental abilities using the example of rotational motions (spin) as they occur in billiards. Five experiments were carried out to evaluate two pa...
