ROI / Binning
The
Teledyne Photometrics
Retiga R Series camera supports both user-defined, arbitrary regions of interest
(ROI) as well as hardware pixel binning modes of 1x1, 2x2, 4x4, 6x6, 8x8, 12x12, and 16x16. Both ROIs and
pixel binning will enable faster frame rates, making focusing and scanning much easier. Pixel binning also has
the advantage
of significantly increasing the signal-to-noise ratio (SNR) of the image, as the effective pixel size is increased,
collecting more light, and the impact of read-noise is diminished relative to adding signals together off chip.
Device Synchronization
Your
Teledyne Photometrics
Retiga R Series camera offers several methods of hardware synchronization via
TTL signals with external devices, including function generators, light sources, shutters and filters. Each camera
has an I/O connector (pin out functions are described in the specifications chapter) on the back for trigger-in/
out and various TTL input and output operations.
An optional cable is available to access primary signals such as “Trigger-in,” “Expose out,” “End of Frame” and
“Shutter Out”. The camera triggers on the rising edge of a TTL signal.
Teledyne Photometrics
Retiga R Series
cameras support three trigger modes:
Trigger-First Mode
In this mode, the camera requires one trigger to begin the acquisition of a stream of images. Once a single trigger
is received, the camera will use its internal clock to acquire the entire image stream, independent of any future
triggers.It is possible to run this triggering mode in either Non-Overlap Mode (left) or Overlap Mode (right).
