computes the thin section color of an anisotropic crystal

Simulates a polarization microscope: light of the given propagation direction passes polarizer, crystal and analyzer, and the transmitted spectrum is converted to RGB. That makes the color a function of the orientation, the sample thickness and the optical setup.

Syntax

oM = spectralTransmissionColorKey(rI,thickness)
oM.propagationDirection = vector3d.Z;
rgb = oM.orientation2color(ori)

Input

rI refractiveIndexTensor
thickness thickness of the sample in nm
ori orientation

Output

oM spectralTransmissionColorKey
rgb list of RGB triplets

Class Properties

rI refractiveIndexTensor
thickness thickness of the sample
propagationDirection vector3d, direction of the light
polarizer vector3d, direction of the polarizer
phi angle between polarizer and analyzer

Example

rI = refractiveIndexTensor.calcite;
oM = spectralTransmissionColorKey(rI,30000)
oM = spectralTransmissionColorKey (Calcite → y↓→x)
 
  thickness            : 30000  
  propagation          : (0,0,1)
  polarizer            : (1,0,0)
  polarizer to analyzer: 90°
