The use of short coherence length laser light for eye length measurement

In this paper, a novel technique, adapted from the use of interferometry in industrial measurement, is discussed. It differs from conventional optical methods such as opthalmophakometry in that it provides a direct measurement. The aim of the use of short coherence length radiation is to provide a much larger and unambiguous measurement range through the use of so-called "white-light interferometry", and it will be shown that a significant improvement upon the precision attainable using ultrasonography may be expected with this approach.
