Figure 3. A comparison of Hyperion 300 endoscopic light source (left) to a
commercial xenon source shows good color matching and improved color
saturation. Color comparison was carried out using an X-Rite color card,
a Weck endoscope and a Richard Wolf HD three-chip camera system.
allow exploration of ever-smaller cavities and reduce the impact
on living organisms. A new small fiber illumination light source
was studied to determine its capabilities as a light source enabling
microendoscopic imaging systems.
Radiometric measurements of the new light source showed
performance up to 40 times better than that of other systems.
The light source was coupled with two imaging systems. The
first imager was a NanEye ultrasmall 1 ; 1-mm, 250 ; 250-
pixel sensor from Awaiba. The second camera consisted of a
three-sensor high-definition camera illuminated through a 500-
μm fiber. In both cases, the new light source allowed for a significant reduction in endoscope size without deteriorating function.
