Simplified illustration showing sequence of events in rolling and global shutter modes. Note that while a single image acquisition is represented, each mode is also compatible with 'overlap' readout, whereby the next exposure begins simultaneous with image readout.
Andor's Neo and Zyla cameras, utilizing the CIS 2051 sensor, and our newest large area Balor sCMOS camera (with its sensor being unique to Andor) were designed with a 5T (5 transistor) pixel architecture to offer choice of both Rolling and Global Shutter modes (also called Rolling and Global Exposure modes). This provides superior application and synchronization flexibility and the ability, through global shutter, to closely emulate the familiar 'Snapshot' exposure mechanism of interline CCDs.
Traditionally, most CMOS sensors offer either one mode or the other, but the sensors of Andor’s Balor, Neo and Zyla sCMOS cameras offer the choice of both rolling and global shutter mode. With these camera solutions, the user benefits from the capability to select (via software selection) either readout mode from the same sensor, such that the most appropriate mode can be chosen dependent on specific application requirements.
