Introduction to Astronomical Photometry

Introduction to Astronomical Photometry by M. Golay
English | PDF | 1974 | 376 Pages | ISBN : 9027704287 | 30.1 MB

The material given in this 'Introduction to astronomical photometry' is the subject matter of a lecture at the University of Geneva. It is, therefore, intended for those students, physicists or mathematicians, who have completed their bachelor's degree or diploma, and are intending to work for their Ph.D. in astronomy. We assume then the elementary ideas of astrophysics, magnitude, colour index, spectral classes, luminosity classes, gradient, atmospheric extinction are already known. The student may find it useful to re-read the work of Schatzman [1], Dufay [2] and Aller [254] before embarking upon the study of this 'Introduction to astronomical photometry'. It is not our aim in this book to deal with every aspect of stellar photometry.

A Practical Guide to Lightcurve Photometry and Analysis (Repost)

A Practical Guide to Lightcurve Photometry and Analysis by Brian D. Warner
English | PDF | 2016 | 418 Pages | ISBN : 3319327496 | 18.2 MB

For those with access to even a modest telescope and CCD camera, this new and improved guide delivers all the information needed to take part in the scientific study of asteroids and variable stars. New techniques in photometry continue to be refined, and expert Brian Warner covers the developing territory in detail for those both new and experienced. Updated to reflect changes in telescope and CCD technology, it also includes an expanded chapter on the analysis of asteroid lightcurves to cover some of the common pitfalls that lead to incorrect answers as well as how to discover an asteroid satellite via lightcurves. With this information, amateur astronomers can use commercially available equipment to determine the rotation rate, size, and shape of asteroids. Similarly, it is possible to discover the size, temperature, and orbits of stars in binary systems by using this powerful technique.

Active Lighting and Its Application for Computer Vision: 40 Years of History of Active Lighting Techniques

Active Lighting and Its Application for Computer Vision: 40 Years of History of Active Lighting Techniques by Katsushi Ikeuchi
English | PDF,EPUB | 2020 | 309 Pages | ISBN : 3030565769 | 105 MB

Computer vision entails both passive and active illumination techniques. Whereas passive techniques observe the scene statically and analyse it as is, by contrast active techniques give the scene some actions and try to facilitate the analysis. In particular, active illumination techniques project specific light, for which the characteristics are known beforehand, to a target scene to enable stable and accurate analysis of the scene.
