Augmented reality (AR) systems have many different applications from consumer electronics devices to military devices. Head-mounted displays have been extensively investigated during the last years. Modern technologies make it possible to manufacture more and more complex devices, and the symbol generators used in such systems continue to improve. FLCOS, AMOLED, and other microdisplays are usually used as a source of image in such type of the systems. Seethrough augmented reality systems can also work with a smartphone. Devices with ever greater resolution and smaller size appear on the market providing small response time and high brightness. While designing the optical architecture for HMD, one usually considers how it works with certain source of image. We have considered several AR optical architectures with flat and curved mirrors as a combiner, and how they work with sources of different type, size, resolution, etc. Thus, the object of the research is to design several optical schemes for augmented reality see-through head-mounted displays working with different sources of image.
Augmented reality systems are becoming very popular nowadays. Head-mounted displays can be used in different fields from entertainment to educational purposes and medicine visualization. In game industry HMD is the best way to combine virtual scenes with real world. Usually FLCOS, AMOLED and other microdisplays are used as a source of image. Such systems require especially designed optical layout to work with certain microdisplay. In virtual reality systems smartphone with special program on it is used as the image generator. In this case the program divides screen into two parts, each part for the one eye. The same idea can be applied in see-through head-mounted displays. Thus, the main object of the research is to analyze the possible optical schemes of the HMD which can work with a smartphone and provide characteristics suitable for the augmented reality.
Augmented reality systems are becoming very popular nowadays. One of the examples of such system is a monocular see-through smart glass display. Smart glasses can way simplify people’s life being. It can quickly find and visualize information, show a map and navigate you in a real time, and do many more different useful things. In such type of a system microdisplay is used as an image generator. We have used amlcd microdisplay with 640×480 resolution, 7.2×5.4 mm display size. This provides required angular pixel resolution of maximum 1.5 arcmin and diagonal field of view of minimum 20 degrees. To forward the image from microdisplay to the eye we have used several mirrors. We have considered a monocular see-through smart glass imaging system with the amlcd microdisplay as a source of imposed image. Thus, the main object of the research is to design and analyze an optical architecture for the monocular smart glass display and to provide required characteristics.
Abstract images with high self-similarity could be used for drug-free stress therapy. This based on the fact that a complex visual environment has a high affective appraisal. To create such an image we can use the setup based on the three laser sources of small power and different colors (Red, Green, Blue), the image is the pattern resulting from the reflecting and refracting by the complicated form object placed into the laser ray paths. The images were obtained experimentally which showed the good therapy effect. However, to find and to choose the object which gives needed image structure is very difficult and requires many trials. The goal of the work is to develop a method and a procedure of finding the object form which if placed into the ray paths can provide the necessary structure of the image In fact the task means obtaining the necessary irradiance distribution on the given surface. Traditionally such problems are solved using the non-imaging optics methods. In the given case this task is very complicated because of the complicated structure of the illuminance distribution and its high non-linearity. Alternative way is to use the projected image of a mask with a given structure. We consider both ways and discuss how they can help to speed up the synthesis procedure for the given abstract image of the high self-similarity for the setups of drug-free therapy.
Recently there is a great interest to the drug-free methods of treatment of various diseases. For example, audiovisual
therapy is used for the stress therapy. The main destination of the method is the health care and well-being.
Visual content in the given case is formed when laser radiation is passing through the optical mediums and elements. The
therapy effect is achieved owing to the color varying and complicated structure of the picture which is produced by the
refraction, dispersion effects, diffraction and interference.
As the laser source we use three laser sources with wavelengths of 445 nm, 520 nm and 640 nm and the optical power up
to 1 W. The beam is guided to the optical element which is responsible for the final image of the dome surface. The
dynamic image can be achieved by the rotating of the optical element when the laser beam is static or by scanning the
surface of the element.
Previous research has shown that the complexity of the image connected to the therapy effect. The image was chosen
experimentally in practice. The evaluation was performed using the fractal dimension calculation for the produced image.
In this work we model the optical image on the surface formed by the laser sources together with the optical elements.
Modeling is performed in two stages. On the first stage we perform the simple modeling taking into account simple
geometrical effects and specify the optical models of the sources.
