Working Principles of CCD and CMOS Sensors and Their Place in Astronomy

Abstract

In this article, information about the properties, working principles and recent developments of CCD and CMOS sensors used in astronomy are given. Until the development of camera technology, sky observations were made using photographic plates in telescopes. With the development of CCD sensors in the 1960s, photographic plates were replaced by powerful cameras with CCD and CMOS sensors. Even today, all observations made in the optical field are made with the data taken by placing these cameras in the ocular part of the telescope. It is of great importance to understand the sensor technology in order to understand the observation techniques. This article has been prepared to fill this gap.

CCD ve CMOS Sensörlerin Çalışma Prensipleri ve Astronomi Alanındaki Yeri

Öz

Kamera teknolojisinin gelişmesine kadar, teleskoplarda fotoğraf plakaları kullanılarak gökyüzü gözlemleri yapılmıştır. 1960'larda CCD sensörlerinin geliştirilmesiyle, fotoğraf plakalarının yerini CCD ve CMOS sensörlü güçlü kameralar aldı. Bugün bile optik alanda yapılan tüm gözlemler, bu kameraların teleskoplara monte edilerek alınan verilerle yapılmaktadır. Gözlem tekniklerini anlamak için sensör teknolojisini anlamak büyük önem taşımaktadır. Bu makalede CCD ve CMOS sensörlerin özellikleri, çalışma prensipleri ve son gelişmeler hakkında bilgi verilmiş ve sensör teknolojisinin astronomide kullanımı incelenmiştir.
