Modeling of the laser device for the stress therapy

摘要

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.
