isochromatic

[¦ī·sō·krə′mad·ik]
(optics)

Pertaining to lines connecting points of the same color.

Here, a snapshot of isochromatic fringe pattern (contours of maximum in-plane shear stress, [[tau].sub.max]) taken by a dynamic photoelastic experiment is shown.
Figure 8 shows the test results of isochromatic fringes for the specimens with different branch angles [theta].
The stress distribution is observed through the isochromatic fringes, and each fringe order is counted by the transition of colors [11]:
An Edwards isochromatic plate 23 cm from the vacuum tube was shielded from light by sheet aluminium and used as the sensor plate.
All subjects underwent a complete neuroophthalmologic examination, which included assessment of BCVA; color vision evaluation (using Ishihara's isochromatic charts); eye movement; pupillary, anterior segment, and fundoscopic examinations; Goldmann applanation tonometry; and OCT examinations using the Cirrus HD OCT (Carl Zeiss Meditec, Dublin) and the Spectralis OCT (Heidelberg, Engineering Inc., Heidelberg, Germany).
To a color-deficient person, all the dots in one or more of the plates will appear similar or the same--"isochromatic." To a person without a color deficiency, some of the dots will appear dissimilar enough from the other dots to form a distinct figure (number) on each of the plates--"pseudoisochromatic."
(14) Briefly, a beam of photoelastic resin was loaded using the fourpoints bending method, which produces stress patterns of pure bending, generating horizontal isochromatic fringes from a neutral axis on the center of the beam.
2) and the fringe order of the isochromatic patterns (Fig.
The photo-elastic response (isochromatic fringes) in a resin rich pocket was recorded to analyze the stress distribution pattern.

The H-W Type A displays specified signal colours, approved by the CIE, but the FALANT displays red, yellow-green and yellowish-white lights that have x, y chromaticity co-ordinates within a common protan/deutan isochromatic zone.
