Detailed Description

OligoWavelengthDistribution is a subclass of the WavelengthDistribution class representing the wavelength probability distribution of primary-source photon packets emitted in an oligochromatic simulation. In principle, the class implements a probability distribution that has a constant nonzero value inside a set of narrow ranges placed around the oligochromatic wavelengths in the simulation, corresponding to the bins defined by the oligo wavelength grid. These bins all have the same half bin width given by 1/1000 of the shortest wavelength in the list (see the OligoWavelengthGrid class). As a result, after normalization, the constant value of the probability distribution inside each of the bins is given by $1 / (N_{bins} w_{bin})$ .

In practice, in the interest of performance, rather than distributing the generated wavelengths across each bin, the class always generates exactly one of the discrete oligochromatic wavelengths. Also, the class always returns the normalized constant probability value regardless of the specified wavelength. This is acceptable because in an oligochromatic simulation this value is queried only for one of the discrete wavelengths anyway.

The oligo wavelength distribution in a simulation is created programmatically rather than directly configured by the user. The list of wavelengths and the bin width are specified by passing an OligoWavelengthGrid instance to the constructor, which used the relevant information from this object.

Constructor & Destructor Documentation

◆ OligoWavelengthDistribution()

OligoWavelengthDistribution::OligoWavelengthDistribution ( OligoWavelengthGrid * wavelengthGrid )

explicit

This constructor can be invoked programmatically to create an oligochromatic wavelength distribution. Before the constructor returns, the newly created object is hooked up as a child to the specified oligochromatic wavelength grid (so it will automatically be deleted), and its setup() function has been called.

Member Function Documentation

◆ generateWavelength()

double OligoWavelengthDistribution::generateWavelength ( ) const

overridevirtual

This function draws a random wavelength from the wavelength distribution. For this class, it returns one of the discrete oligochromatic wavelengths with equal probability.

Implements WavelengthDistribution.

◆ probability()

double OligoWavelengthDistribution::probability ( double wavelength ) const

overridevirtual

This function returns the probability of the distribution at the given wavelength. For this class, the function always returns the normalized constant probability value $1 / (N_{bins} w_{bin})$ regardless of the specified wavelength. This is acceptable because in an oligochromatic simulation this function is called only for one of the discrete wavelengths anyway.

Implements WavelengthDistribution.
