The software presents a selection of five of the most common binning patterns;
1x1, 2x2, 4x4, 8x8, and 16x16 pixels. For example, if you enter 4x4 binning the
CCD-chip is notionally divided into a matrix of superpixels which each measure
4x4 pixels and provide a signal for readout.
define a Custom Binning Pattern. Check the Custom radio button and enter
the dimensions of the superpixels (as a number of pixels vertically and
horizontally) in the text boxes.
By a process of binning charge vertically into the shift register from several rows at
a time (4 rows in the above example, representing the height of your superpixels),
and then binning charge horizontally from several columns of the shift register at a
time (4 columns in the example, representing the width of the superpixels), the
system is effectively reading out charge from a matrix of superpixels which each
measure 4x4.
The result is a more coarsely defined image, but faster processing speed, lower
storage requirements, and potentially a better signal to noise ratio.
