Full textPhosphenes, or light flashes, have been reported by astronauts since the first Apollo flights to the Moon. They are usually described as occurring in the dark and typically before falling asleep. The light flashes are thought to originate as an effect of high- energy particles interacting with the visual system. The study presented in this thesis investigates the hypothesis of a direct excitation of the rod photoreceptors inside the retina and in particular the interaction between carbon ions and rods. Also the retinal and cortical electrophysiological response of mice submitted to carbon ions irradiation have been studied. This thesis has been developed as a section of the ’Anomalous Long Term Effects on Astronauts’ (ALTEA) program, and all the experiments concerning this thesis took place on ground. The objective of the ALTEA project is more general, and is aimed to assess the functional risks on the central nervous system due to particle flux in microgravity conditions during long term space mission. ALTEA includes a series of experiments both in orbit and on ground. The experiments on board International Space Station will contribute to define the causes of the anomalous phosphene perception of the astronauts by detecting the incident particles through the head of the astronauts and concurrently monitoring the central nervous system functionality. The experiments on ground include the direct irradiation with carbon ions of the outer segments of the rods, and an animal model to investigate the retina/cortex responses of mice irradiated in controlled laboratory experiments. In these experiments on ground I directly contributed in the preparation, the test and the optimization of the experiments and in the following analysis of the data. The whole project has been supported by the Italian Space Agency. The outline of this thesis includes an introduction to the interdisciplinary ALTEA program in the first chapter. In the second chapter ALTEA-MICE (Mice intermittent Irradiation with Concur- rent Electrophysiological monitoring) study is described: the experimental sessions as well as the evidences in the electrophysiological responses of the mouse retina have been described in detail. My role has been chiefly the experimental set up, and I also collaborated on the data analysis. The main results of this investigations have been published. In the third chapter the system of the rod outer segments in suspension and the mechanism of the activation of the photoreceptors are described. The fourth chapter deals with the radiation effects in the biological tissue, and in the fifth chapter there is particular regard to the effects of radiation on samples containing a suspension of rods extracted from bovine retinae. The effects on the rod photoreceptor rhodopsin has been studied: measurements have been performed irradiating with carbon ions the outer segments of the rods in suspension. The amount of the isomeric transformations (bleaching) of the molecules of chromophore into the photoreceptor gives the extent of the effects of radiation. I collaborated to the experiment and carried out the following data analysis. Finally, in the sixth chapter the process of the photo-isomerization of rhodopsin is explained by a model: the process starts with the water radiolysis and the formation of hydroxyl radicals OH in order to achieve the lipid peroxidation, then there is the subsequent emission of visible photons which are responsible for the photoreceptor bleaching. Since rhodopsin is surrounded by phospholipids, present in high concentration in the disc membranes, the effect of chemiluminescence is proposed to be the cause of the photo-transduction cascade and the light flash perception as a consequence. In order to test this hypothesis, a series of experiments was aimed at studying the effects of the hydroxyl radicals produced in an enzymatic way. The main results of this work are illustrated in chapter six, and have been published.

In this thesis, we investigate the illumination system design of flash lens with asymmetric field light source. And we research the distribution of rays and observe the variation of light field by optical software, LightTools and CODE V. Besides, in order to use light power effectively and achieve the design targets, we design two lenses, which are symmetric lens and asymmetric lens. In the end of thesis, we analyze the distinctions, such as illumination, efficiency, tolerance and limitation between two designs.

In this article, based on the meteor's video in 2014, we use the vision program designed by LabVIEW to obtain the light curve of meteor, and analyze the phenomenon of meteor flash. Using the characteristics of flash phenomenon, the source and cause of the origin of meteoroids, a model of flashing phenomenon of meteoroids is proposed. It is known from 108 meteor images data that the flashing phenomenon is concentrated in the Perseids meteor shower (Per) and the Eta Eridanids meteor shower (Eri). The origin of meteoroids of these two meteor showers is comet, and the characteristics of the flashing phenomenon are summarized as The time interval ∆t is about 80-120 ms, and the changing of magnitudes ∆m is between 0.1-0.35. Finally,according to the foregoing characteristics, the methane suddenly combustion model is proposed to explain the phenomenon of meteor flash.

As technology advances, there are more and more extensive application of optical elements, of which Fresnel lens is one of the representative products, mainly is the use of micro-structure to change the light path. Compared with the conventional convex lens, lighter is it’s advantage .Most of the present Fresnel lens are for solar concentrator systems, to collect and concentrate light to a small area, increasing the light usage. This study aims to examine the optical characteristics of Fresnel lens, to apply on camera flash light of mobile phones. Today, in order to reduce its power consumption ,mobile flash light switch from the helium flash to LED as substation, but the LED general lighting angle is too wide, so that part of the light falls outside the scope of photography, resulting in limited performance and efficiency. Thus, by characteristics of the Fresnel lens, to adjust the angle of the light irradiation to improve lightening efficiency. The primary object of this study set out with a Fresnel lens ,of which diameter is 5.5mm,By using optical design software TracePro, to design its optical micro-structure, so that large emission angle of LED light source falls within ± 30 ° angle, and to strengthen to 2.4 times in the axis direction. In mold design process, using Moldex3D software to do mold flow analysis helping with mold design ,looking out for best gating design and molding parameters, In the injection molding process, by trial and error method to find shape window, then using Taguchi method to study the influences ,plastic forming parameters of temperature, mold temperature, injection speed and holding pressure process parameters on the forming quality of a Fresnel lens. The experimental results show that holding pressure is the important factor affecting the optical quality ,by the best parameters measured and light distribution curve, the results obtained were compared with analysis of the angle error is less than 2%.
