Description:

Introduction to image sensors

Capturing and recording an image is a fundamental process of data taking in nearly all branches of science and medicine. It has evolved from hand sketching of the scene through imaging based on photo-chemistry of silver compounds to the present-day electronic imaging. Electronic image capture, manipulation of images, and image transmission have become efficient and inexpensive allowing a wide adoption of the techniques outside of science; in areas such as entertainment, communication, education, or retail electronics – the cell phone. CCD and CMOS are the two most commonly used image sensors and they will be the focus of this webinar. The presentation begins with a general overview of the opto-electronic characteristics of image sensors. This is followed by a discussion of the structure, operation, and readout schemes of the two sensors. The webinar concludes with examples of applications where either CCD or CMOS would be a better choice of the image sensor.

Topics of presentation:

1. Become familiar with opto-electronic characteristics of image sensors
2. Learn about the structure, operation, and types of a CCD and CMOS
3. Learn about applications that would favor using either CCD or CMOS

Speaker Biography:

Slawomir S. Piatek has been measuring proper motions of nearby galaxies using images obtained with the Hubble Space Telescope as a senior university lecturer of physics at New Jersey Institute of Technology. He has developed a photonics training program for engineers at Hamamatsu Corporation in New Jersey in the role of a science consultant. Also at Hamamatsu, he is involved in popularizing a SiPM as a novel photodetector by writing and lecturing about it, and by experimenting with the device. He earned a Ph.D. in Physics at Rutgers, the State University of New Jersey, in 1994.
