Ian S. McLean

Modern astronomy relies heavily on the observation and interpretation of weak light signals in the universe. 1970, Bell Laboratories first announced the concept of charge coupled device (CCD). Astronomers see the importance of CCD in astronomical observation, so they actively participate in or support the development of CCD chips specially designed for astronomy. Nowadays, CCD chips have been widely used in observatories, and professional astronomical CCD chips are almost perfect.

This book tells the great development achievements of astronomical observation in recent years. From 1970 CCD to the present era of super-large telescope, the content involves the main methods and technologies of obtaining astronomical images in full spectral range. The development of CCD is used to link a series of astronomical electronic imaging technologies and methods.

Book *** 14, 1. Electronic imaging in astronomy and its development history: 2. How to overcome the influence of the atmosphere and the application of adaptive optics; 3. The astronomical telescope and the latest super-large astronomical telescope technology are introduced. 4. Explain the important role of astronomical observation instruments in astronomical discovery, and explain the working principles of spectrometers and cameras; 5. Described the classification of astronomical observers, and introduced semiconductors; 6. The design and construction of the observatory are further described. 7-8. The working principle and practical operation of CCD are expounded respectively. 9. The calibration problems of most electronic imaging instruments are described, and the concepts of flat field and signal-to-noise ratio are introduced. 10. This paper introduces the image processing and analysis technology. In the following chapters, the development of CCD is used to link electronic imaging technologies of various wavelengths; 1 1. Electronic imaging at infrared wavelength: 12. Electronic imaging at ultraviolet wavelength, X-ray wavelength and γ-ray wavelength. 13. Electronic imaging of submillimeter wave and radio wavelength. 14. The future astronomical observation is prospected, and the application prospect of the new observatory is described.

Professor McClane, the author of this book, is one of the authoritative experts in the world who apply electronic imaging system to advanced observatories. From 65438 to 0974, he received his doctorate in astronomy from the University of Glasgow, England. During his ten years at the Royal Observatory in Edinburgh, he developed the first spectropolarimeter based on CCD imaging. During the 10 years at Keck Observatory, he also developed groundbreaking astronomical instruments many times.

This book tells a series of basic astronomical observation techniques and methods. Through detailed case analysis, the working principle and technology of astronomical observation instruments such as cameras, spectrometers and telescopes are emphasized. It is suitable for photoelectric readers and senior college students and graduate students who are interested in modern observational astronomy.
