The reflected light is detected by an orthogonally placed analyzer which filters out surface reflections in order to produce a high-contrast reflected light image of flowing RBCs within the microcirculation [ 36].
In comparison to the dichromatic reflectance model [19], the diffuse and specular surface reflections are analogous to the direct transmission, t i x i, and atmospheric veiling, (1-t i a, respectively.
It is thought that fish mistake the shaded area for a safe refuge; another interpretation is that the canopy aids the bird's vision by reducing surface reflections.
In high myopic corrections, a cosmetic improvement is effected if the lenses are made of dense flint glass (refractive index 1.69) and coated with a film of magnesium fluoride to nullify the surface reflections.
Actually, the telescopic view is always dimmer than the direct view because of light losses in the telescope due to glass absorption and surface reflections and because the exit pupil of the telescope may be smaller than the pupil of the eye, thus reducing the angle U′.
To estimate the potential for surface reflections in recently introduced intraocular lenses (IOLs) and to determine optic surface designs that will reduce surface reflections.
