Three-dimensional (3-D) imaging techniques have the potential to establish a future mass-market in fields of entertainment and communications. Integral (InI), which can capture display true 3-D color images, has been seen as right technology for viewing audiences more than one person. Due advanced degree its development, InI could be ready massive commercialization coming years. This development is result strong research effort performed over past few In this sense, paper devoted reviewing...
Thermal energy storage (TES) is extremely important in concentrated solar power (CSP) plants since it represents the main difference and advantage of CSP with respect to other renewable sources such as wind, photovoltaic, etc. a low-carbon emission source energy, TES allows have availability dispatchability using available industrial technologies. Molten salts are used material because their high operational temperature stability up 500°C. Their drawbacks relative poor thermal properties...
One of the main challenges in three-dimensional integral imaging is its limited depth field. Such a limitation imposed by diffraction, among other factors. The easiest way to improve field reducing numerical aperture microlenses. However, such an improvement obtained at expense important deterioration spatial resolution. We propose technique, which novel context imaging, for improving with no based on amplitude modulation array phase elements, can substantially figure merit product focus and squared
Engineers and scientist have a long tradition in trying to improve the thermophysical properties of convective heat carriers such as water transformer oil. Technological developments last decades allow dispersion particle sizes ranging between 10 100 nm these liquids. In large number recent studies resulting nanofluids been reported display anomalously high increase transfer. The present study compiles experiments from five independent research teams investigating transfer nanofluid flow...
Integral imaging systems are devices that provide 3D images of objects. When integral work in their standard configuration the provided reconstructed pseudoscopic; is, reversed depth. In this paper we present, for first time believe, a technique formation real, undistorted, orthoscopic by direct pickup. The is based on smart mapping pixels an elemental-images set. Simulated experiments presented to support our proposal.
One of the main limitations integral imaging is narrow viewing angle. This drawback comes from limited field view microlenses during pickup and display. We propose a novel all-optical technique which allows substantial increase any microlens therefore angle integral-imaging displays.
Previously, we reported a digital technique for formation of real, non-distorted, orthoscopic integral images by direct pickup. However the was constrained to case symmetric image capture and display systems. Here, report more general algorithm which allows pseudoscopic transformation with full control over parameters so that one can generate set synthetic elemental suits characteristics Integral-Imaging monitor permits depth size reconstructed 3D scene.
One of the main challenges in integral imaging is to overcome limited depth field. Although it widely assumed that such limitation mainly imposed by diffraction due lenslet imaging, we show most restricting factor pixelated structure sensor (CCD). In this context, demonstrate proper reduction fill pickup microlenses, field can be substantially improved with no deterioration lateral resolution.
Heat convection is an important phenomenon in the process of cooling polymer spur gears running dry conditions, which ultimately affects strength gears.In order to gain some insight into this phenomenon, a numerical heat model for proposed work, based on detailed CFD simulation operating conditions and it allows us investigate through their external surfaces.The performance illustrated with several examples, parametric study has been conducted observe variation transfer coefficients face...
Three-dimensional images generated by an integral imaging system suffer from degradations in the form of grid multiple facets. This multifacet structure breaks continuity observed image and therefore reduces its visual quality. We perform analysis this effect present guidelines design lenslet parameters for optimization viewing conditions with respect to degradation. consider terms field view, observer position pupil function, parameters, type reconstruction. Numerical tests are presented...
One of the main challenges in 3-D display and visualization is to overcome its limited depth field. Such limitation due fast deterioration lateral resolution for out-of-focus object positions. Here we propose a new method significantly extend The based on combined benefits proper amplitude modulation microlenses, application deconvolution tools. Numerical tests are presented verify theoretical analysis.
Conventional macro objectives are generally used as relay systems in the capture stage Integral Imaging. This choice leads to microimage overlap and shift, which produce undesirable effects on reconstructed three-dimensional images, such loss resolution image distortions. In this paper, we propose demonstrate a new architecture for stage. Our method uses telecentric system overcome conventional drawbacks. Experiments conducted with our show an important improvement quality of displayed images.
In modern high-NA optical scanning instruments, like microscopes, the refractive-index mismatch between sample and immersion medium introduces a significant amount of spherical aberration when imaging deep inside specimen, spreading out impulse response. Since such depends on focalization depth, it is not possible to achieve static global compensation for whole 3D in microscopy. Therefore depth-variant response generated. Consequently, design pupil elements that increase tolerance this great...
One of the main challenges in 3D integral imaging (InI) is to overcome limited depth field displayed images. Although this limitation can be due many factors, phenomenon that produces strongest deterioration out-of-focus images facet braiding. In fact, braiding an essential problem, since InI monitors are not feasible if problem solved. paper, we propose a very simple method for overcoming effect which serious realization TV based on InI. Hybrid experiments presented verify theoretical analysis.
