MONOCHROMATIC ILLUMINATION

Ultrahigh-resolution full-field optical coherence tomography using spatial coherence gating and quasi-monochromatic illumination.

We developed an ultrahigh-resolution full-field optical coherence tomography (FF-OCT) microscope that is based on the spatial, rather than the temporal, coherence gating. The microscope is capable of observing three-dimensional microbiological structures as small as 0.4 μm × 0.4 μm × 1.0 μm (xyz) using quasi-monochromatic light and a liquid crystal retarder. Unlike traditional FF-OCT systems, t...

The effects of monochromatic illumination on early eye development in rhesus monkeys.

PURPOSE Influence of longitudinal chromatic aberration (LCA) on emmetropization during early eye development has not been studied in primates. We investigated the effects of quasi-monochromatic lighting on refractive development and eye growth in rhesus monkeys. METHODS Infant rhesus monkeys were raised under one of three lighting conditions for 51 weeks: quasi-monochromatic blue light (peak ...

LEMMA . At most (kn)'g"ulk k-sets Sc [ n ] have IP(S)I <u . Proof. Let a,< . . . < a k denote the elements of S. Call i doubling if P(a, , . . ., a i) has double the size of P(a, , . . ., a i 1 ) . There are at most lg u doubling i. Hence there are at most k'g" choices for doubling positions i and at most n'g" choices for the values a i . If i is not doubling then a i = x y, where x, y E P(a, ,...
