Automatic Real Time Mean
With ART Mean, mean images are created automatically. These
mean images enhance image quality as a result of noise reduction.
For performance reasons, this process has a tolerance, so the
actual number of frames used to create the mean image may differ
by a few scans from the configured value. However, the
improvement of the signal-to-noise ratio never varies more than
±10 %. The effect on the q-value is ±0.5 or less.
To check the number of images averaged, select
“Image ► Image Information” from the menu bar of the analysis
window. In the “OCT Image” section, the number of images
averaged is given in the “ART Mode” entry.
BluePeak Blue Laser Autofluorescence
Cross-polarized images can be acquired while the filter wheel is
pointed at “P” . Cross-polarized images will be darker than normal
reflectance images and may contain polarization effects. This
image contrast effect is caused by birefringent properties of the
examined structure.

Heidelberg Eye Explorer 2
HEYEX 2 is the next generation Heidelberg Eye Explorer platform
which provides centralized management of image data in
ophthalmology.
High resolution
If you select HR as the scan resolution mode in the acquisition
module, images are acquired with a higher spatial scan resolution,
but with a low scan rate. HR acquires more data points over a
longer time period and requires more time and space for data
storage.
