Fiber Optical Sensors

Light transmission in the reflection fiber system, located in external optical media, has been investigated for application as sensors. The system was simulated by different models, including external cavity parameters such as the distance between light emitting and receiving fibers and mirror positioning distance. The sensitivity to a linear displacement of the sensors was studied as a function of the distance between the tips of the light emitting fiber and the center of the pair reflected light collecting fibers, by positioning a mirror. Physical fundamentals and operating principles of the advanced fiber optical sensors were revealed.

The textbook examines the most common diagnostic errors of ophthalmologists when making a clinical diagnosis of "cataract". Clinical examples point to a more critical view of the cataract diagnosis. Due to the fact that most of the errors are based on a superficial examination of the eye, clear recommendations are given for conducting a clinical ophthalmological examination of cataracts. At the same time, special attention is paid to the types of examination of the lens with the help of a slit lamp, to the peculiarities of performing various types of ophthalmoscopy with moderate opacity of optical media.

Abstract The rise of live-streaming platforms, and the related surge in popularity of esports, remind us that there is a politics of watching play. This article extends intensified scholarly interest in game spectatorship, offering a materialist consideration of the embodied work involved in spectating competitive game play. Most readily associated with the discursive alignments between competitive gaming and/as sport, the active camera mode used by esports competitors and “shoutcasters” facilitates analyzing the highly kinetic action of team-based combat in first-person shooters and multiplayer online battle arenas. Here, we draw from microanalyses of audio-visual recordings taken as individual participants spectated a Dota 2 match. Examining the cognitive and perceptual competencies they draw from, we argue that participants are incorporated into apparatuses of perception associated with militarized optical media. While at a discursive level esports spectators may be watching sports, at a material level they are playing with the logics of drones.
