However, its flickering visual stimuli may cause discomfort, even induce migraine and seizure attacks among its viewers. This paper presents a novel approach to induce SSVEP with high signal-to-noise ratios (SNRs) using composite color lights flickering near or above its critical flicker fusion (CFF) thresholds. Different combinations of frequencies, relative phases and pulse widths of the stimuli waveforms were tested for their effectiveness to produce high SNR values among their SSVEP responses. Results of our experiments were analyzed and studied. The rationale behind the special design of high-frequency polychromatic stimuli and the implications towards the development of an effective brain-display interaction (BDI) system were also discussed.","PeriodicalId":183646,"journal":{"name":"2014 13th Workshop on Information Optics (WIO)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124025478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper I report that combination of this light field camera and integral display has useful features for 3D image capture and reconstruction. Refocusing function is based on 3D information contained in light field data and this fact means that a light field camera captures 3D images and encodes them in the 2D sensor plane by micro lens array. This 3D capturing is unique in two points; one is that a light field camera acquires not real 3D object images but 3D image plane compressed in axial direction by the object lens in proportion to ratio of longitudinal and lateral magnification. So when captured 3D image plane is shown on the integral display, the actual 3D image is reconstructed near display screen like an embossed carving. The other point is that the reconstructed image is of higher resolution than density of micro lens. Light filed data by the light field camera basically contain full resolution information not limited by density of micro lens. This implicit resolution in encoded data comes out, when the light field data is decoded by the integral display thorough optical convolutional process.","PeriodicalId":183646,"journal":{"name":"2014 13th Workshop on Information Optics (WIO)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121669271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, encrypted sensing system based on CS is composed of digital micromirror device for random intensity modulation and single pixel camera.

This platform is based on a dielectric multilayer that sustains Bloch surface waves (BSWs). BSWs are electromagnetic surface waves excited at the interface between a truncated periodic dielectric multilayer and a surrounding media. The modification of the top surface to customize a complete 2D micro-system can be produced using e-beam writing, optical lithography or other patterning techniques. The results obtained confirm the possibility of developing a robust multilayer platform that would pave the way for integration of photonic components in photonic chips using standard wafer-scale production.","PeriodicalId":183646,"journal":{"name":"2014 13th Workshop on Information Optics (WIO)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121232054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most widely used algorithm is the hybrid input-output (HIO) algorithm because of its ability to avoid local minimum. Unfortunately the presence of noise in the images acquired disturbs the convergence of the algorithm. A few solutions have been proposed in order to improve the quality of the recovered images but they unfortunately still suffer from oscillations even though they are less susceptible to noise than the traditional method. In this paper, we propose a robust method to reconstruct diffraction patterns which are corrupted by Poisson noise. Our method relies on the HIO algorithm, combined with a Gaussian filter to avoid the oscillation and with normalized convolution (NC) to improve the quality of the filtered images. We describe the principle of our approach and present the results of simulations which have been made to evaluate its performance and to draw a comparison with the others existing algorithms that have been developed so far.","PeriodicalId":183646,"journal":{"name":"2014 13th Workshop on Information Optics (WIO)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129430088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
