Engineering—Mechanical) Three-dimensional Holographic Lithography and Manipulation Using a Spatial Light Modulator by

Structured light illumination is an active 3-D scanning technique based on projecting/capturing a set of striped patterns and measuring the warping of the patterns as they reflect off a target object’s surface. In the case of phase measuring profilometry (PMP), the projected patterns are composed of a rolling sinusoidal wave, but as a set of timemultiplexed patterns, PMP requires the target sur...

We experimentally generate speckle patterns with non-Rayleigh statistics using a phase-only spatial light modulator. By introducing high order correlations to the input light fields we redistribute the intensity among the speckle grains, while preserving the granular structure of the pattern. Our method is versatile and allows for generating speckle patterns with enhanced or diminished contrast...

This study investigated the effects of High Variability Phonetic Training (HVPT) in training both the perception and production of English highfront vowels /ɪ/-/iː/ and high-back vowels /ʊ/-/uː/ by Cantonese ESL learners. Results showed that the HVPT was generally effective in improving the subjects’ perception of the two vowel pairs and perceptual learning could generalize to new words and new...

The meaning of spatial relations have been intensively studied in cognitive science research. A spatial template is one of the typical representations of spatial relations, which maps a position of a located object to its acceptability for the corresponding spatial term. Spatial templates have been investigated for several orthogonal spatial relations. However, diagonal spatial relations have a...

A dynamic optical reconstructed system for digital hologram is developed using two commercially available twisted-nematic-liquidcrystal spatial light modulators (TNLC-SLMs), which are operating in the amplitudeand phase-mostly modulation modes, respectively. The complex modulated properties of this cascaded two TNLC-SLMs can be analyzed by the Jones matrix method and also be measured in experim...

Selected mapping (SLM) peak–power reduction [1] is distortionless as it selects the actual transmit signal from a set of alternative signals, which all represent the same information. Usually, the specific signal generation information needs to be transmitted and carefully protected against bit errors. Here, we propose an extension of SLM, which employs scrambling and refrains from transmitting...
