Özet:Lazerler temel özellikleri açısından beyaz ışık kaynaklarına göre önemli farklılıklar gösterirler. Bunlar arasında lazerlerin en temel özelliği monokromatik yapıya sahip olmalarıdır. Bu özellikleri nedeniyle lazerler günlük hayatta önemli uygulama alanları bulmakta olup bu uygulama alanlarından birisi de uzaklık ölçümünde lazerlerin kullanılmasıdır. Lazerle uzaklık ölçümünde "Girişim Ölçme Metodu", "Demet Modülasyon Telemetresi" ve "Atma Eko Teknikleri" olmak üzere üç temel yöntem kullanılmaktadır. Bu üç farklı yöntemin de birbirlerine göre önemli farklılıkları ve üstünlükleri bulunmaktadır.
Abstract:Lasers show considerable differences in terms of their basic features compared to white light sources. Among them, monochromatic structure is the most basic feature. Because of these features, lasers find important application areas in daily life. One of the application areas of lasers is the use of lasers in distance measurement. Three different methods are used in the laser distance measurement: Interference Measurement Method, Beam Modulation Telemetry and Pulse Echo Techniques. These three different methods have significant differences and advantages over each other.
The use of solar energy systems among renewable energy sources is gaining importance day by day. Photovoltaic systems have a special importance among solar energy systems. Although the incident light flux increases the electrical energy produced in the solar panels, the increase in temperature caused by the radiation reduces the efficiency of the solar panels. Important methods are being studied in order to increase this falling efficiency. Dynamic cooling systems are one of the important methods used in this field. In this study, a dynamic cooling mechanism was designed and developed for a double-faced photovoltaic power generation system. From this point, it was concluded that temperature is one of the important factors affecting the efficiency of solar panels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
