In the last few years, light measurement has evolved from a dependence on traditional emulsion-based film photomicrography, to one where electronic images are the media of choice. The imaging recording device is one of the most critical components in many experiments so understanding the process of how the light images are recorded and the choices available can enhance the quality of the light measurement data. In this guide we aim to provide an understanding of the basics of light detection and also help select a suitable detector for specific applications. High performance digital cameras can be defined by a number of variables. Each of these variables is discussed in detail in subsequent sections but a brief description is included here for convenience.
Digital cameras come in 4 primary types based on the sensor technology they use and these are: CCD's, EMCCD's, CMOS and ICCD cameras.
The most common scientific camera, the Charge Coupled Device camera (CCD), comes with three fundamental architectures and these are Full Frame, Frame Transfer and Interline format. The different architectures and their inherent strengths and weaknesses will be covered more soon.
