The development of devices based on an acousto-optical filter (AOTF) is widespread. It is essential to be able to accurately simulate acousto-optic diffraction when modelling optical systems that include AOTF. However, the AOTF model is not a built-in object in optical design software. From the other hand, it is usually impossible to integrate the properties of AOTFs calculated in other special software into a standard optical design program. Therefore, in this paper, we considered possible methods for evaluating and modelling the characteristics of AOTFs in the design of optical systems.
The Student Research Laboratory for Optical Engineering was founded in 2014 at the Dept. of Applied and Computer Optics in ITMO University. Students there work on various optical, design, lighting and technological projects and find like-minded team for creating of coworking-groups in the student laboratory. It is highly difficult to provide practicaloriented activity in the laboratory without the use of elementary optical elements, which are supposed to be components of educational projects and activities. The review of traditional approaches for production of optical elements showed that currently there are no technologies in the optical industry, capable of solving this problem. The produced optical components must meet following requirements: a). to be capable to visualize optical elements work principles; b). to be produced rapid and laborless; c). to be affordable for students. This paper presents results of the experimental work, the technological process and the obtained elements characteristics, which were produced in two different ways. The optical elements angles were measured by goniometer and compared with preset tolerances.
Through the creation of a large number of interactive optical projects in pursuit of this goal, the laboratory has realized that the most effective educational approach is one that presents information in a fun, engaging, and informative manner. Hence, the idea for an optical labyrinth was born. This labyrinth allows students to interact with and learn optical phenomena in real time, presenting tangible benefits for ongoing education of optics and photonics in schools and universities.
