Suppliers of Microscopy Peripherals - Supplemental Table not in Print Edition
First, the number of Charge-Coupled Device (CCD) cameras for biological microscopy is staggering (the accompanying table shows typical properties of one-third of available models). The cameras are composed of a sensor (the CCD) and an analog-to-digital converter; the reading of light by individual sensor elements generates an image composed of a two-dimensional array of pixels (or "picture elements"). CCD cameras have various operational architectures. Interlaced cameras scan an image in two steps, usually odd and even horizontal lines, and then reconstruct it in a buffer; this method was developed to decrease monitor flickering....
