On Producing Colours Using Birefringence Property of Transparent, Colourless Stretched Cellophane
Abstract
The authors discuss the birefringence property of transparent, colourless stretched cellophane and describe the colours produced when one or more layers of such cellophane is sandwiched between a pair of polarisers. The parameters that can be altered in order to vary the colours are explained, and a convenient method is suggested for viewing the range of colours produced.

Non-crystalline materials can also be birefringent, among them several commercially available transparent adhesive tapes.
“Non-crystalline materials can also be birefringent, among them several commercially available transparent adhesive tapes [14].”
If the phase shift deviates from exactly λ/4, the output polarization becomes elliptical instead.
“If the phase shift deviates from exactly λ 4 , the output polarization becomes elliptical instead [14].”
In transparent polymer films, the optical axis typically aligns with the edges of the tape.
“In transparent polymer films, the optical axis typically aligns with the edges of the tape.”
A photon whose polarization enters the tape at a 45° angle to the optical axis experiences a retardation of the component perpendicular to the optical axis relative to the component parallel to it.
“a photon whose polarization enters the tape at a 45 ◦ angle to the optical axis experiences a retardation of the component perpendicular to the optical axis relative to the component parallel to it.”
This retardation converts the linearly polarized photon into an elliptically polarized one.
“This converts the linearly polarized photon into an elliptically polarized one (Section 3.2) [14].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
