2.6 System Overview
2.6.1 System Description
CLARUS 500 is a non-contact, high-resolution imaging device for in
vivo imaging of the human retina. Imaging modes include:
• True color reflectance imaging
• Infrared reflectance imaging (IR)
• Fundus autofluorescence with green or blue excitation (FAF-G
and FAF-B)
• Stereo imaging
• External eye imaging
2.6.1.1 Principles of Operation
Using a monochromatic camera, a broad line of illumination scans
across and detects the retina.
Red, green and blue LEDs (light emitting diodes) sequentially illumi-
nate to generate true color images. The broad bandwidth of LEDs
gives a true color rendering. Blue and green LED illumination for
FAF (fundus auto-fluorescence) enables fluorescence imaging.
By illuminating only a narrow strip of the retina at a time, the illu-
mination stays out of the viewing path, keeping haze and fluores-
cence of the anterior segment out of the retinal image and allow-
ing a clear view of much more of the retina than the annular-ring il-
lumination used in traditional fundus cameras. The design allows a
single exposure to image an area of the retina previously covered
by the 7-fields in the early treatment of diabetic retinopathy study
(ETDRS).
