- n. A fault that develops in thin charge-coupled devices when they behave as etalons
Sorry, no etymologies found.
By contrast, eXcelon sensors not only counter etaloning, they also boast ~90% peak quantum efficiency and do not increase dark current.
In addition, eXcelon back-illuminated sensors significantly reduce etaloning, the problematic appearance of fringes due to constructive and destructive interference in the device's back-thinned silicon while imaging in the NIR region (750-1100nm).
When eXcelon technology is applied to popular EMCCD devices, the result is a detector with sub-electron read noise, superb sensitivity, low dark current, little if any etaloning, and high frame rates - a combination unmatched in the world of CCD/CMOS sensors.
"For example, for a long time, it has been known that etaloning in the near-infrared region is a significant problem in back-illuminated CCDs.
