碩士 === 國立高雄第一科技大學 === 電機工程研究所碩士班 === 103 === The awareness of Ophthalmological care have been risen gradually in recent years in Taiwan. The average age for Taiwanese to develop a eye diseases is around 40 years old. Therefore, it is important to have regular check-ups and learn about early prevention. Due to the raising awareness of ophthalmological care in Taiwan, the demand for eye care products is also increasing. In oder to accommodate the uprising necessity. This study will focus on transforming the commonly used ophthalmoscope into a wearable electronic device, and development of such diagnostic diagnostic medical devices for use on the network cloud. The experiments will prove that 3D device is more appropriate than 2D device, and the new device will be able to diagnose more patients in the future. The design is divided into two parts: 1. The image recognition experiment: this experiment will investigate the space frequency and contrast recognition changing rate of three-dimensional image and two-dimensional image. The change in frequency space to the human eye is from three-dimensional image recognition rate is 6% higher than the two-dimensional image recognition rate. 2. Wearable 3D ophthalmoscope design: The design of wearable mechanism framework is based on Google glass. Based on image recognition experiment, agency design is devised into a 3D mechanical design. The optical design is mainly based on the demands of the ophthalmoscope regulation and design for 2.5 times the fixed focus Prism right angle turn telecintric imaging system, We use a large aperture to increase the amount of light(F/#= 2.0) to replace of additional light source. The design of the lens simulation added the visible spectrum and near infrared spectroscopy to increase physician diagnosis foundation. According to additional references, the best wave lengths for red spectroscopy penetration of to human eye tissues are 965nm and 985nm.
