"Scientific Detectors for
Astronomy" |
|
Chile is home to the largest collection of optical and infrared telescopes in the world. An astronomical facility can be divided into two main parts: (1) the telescope that collects the light and, (2) an instrument that measures the light. Perhaps the most important part of the instrument is the detector that senses the light. The performance of the telescope-instrument system is a direct function of the performance of the detector: an instrument with an outstanding detector on a 4-metre telescope can outperform an instrument with a poor detector on an 8-metre telescope. Thus, it is critical for every telescope to have the best detectors possible. This technical seminar will give an overview of the types of scientific detectors that are used at the major astronomical observatories. The detectors that will be discussed include CCDs and CMOS-based imaging sensors that are used for ultraviolet, visible and infrared wavelengths. Short Course Outline
Introduction & 6 steps of digital imaging Speaker Biography James W. Beletic has over 25 years experience in visible and infrared focal planes. He received a Ph.D. in Applied Physics from Harvard University and has held leadership positions at major research centers in the United States and Europe, including MIT Lincoln Laboratory, Georgia Institute of Technology, the European Southern Observatory and the Keck Observatory. He has developed new types of detector designs and his research groups have produced detector systems that have been used on 23 telescopes at 16 observatories in the United States, Hawaii, Chile and the Canary Islands. Dr. Beletic is currently the Director of Astronomy and Civil Space at Teledyne Imaging Sensors. |
