void	SetSignalFieldAndSignalRegion (ComplexField signalField, IRegion1D2D signalRegion)
	Sets the desired output field and the optimization region at the same time. More...

Public Attributes
bool	AllowPhaseFreedom
	Determines whether phase freedom is to be allowed during the design.
bool	AllowScaleFreedom
	Determines whether scale freedom is to be allowed during the design.
int	EmbedFrameWidth
	Width of the frame in which the field is embedded. For two-dimensional fields, during embedding the number of sampling points in each direction is increased by two times EmbedFrameWith. For one-dimensional fields only the x-direction is affected. No embedding is performed if EmbedFrameWidth is set to zero.
ComplexField	InputField
	Input field (optional).
bool	InputFieldHasSphericalPhaseRadius
	Determines whether a spherical phase radius is given for the input field
bool	InputFieldIsConstant1
	If this variable is true, a constant input field is assumed and thus the InputField variable is ignored. However, Wavelength and PixelSize stored in InputField are still of concern.
double	InputFieldSphericalPhaseRadius
	Optional spherical phase radius for the input field
bool	LimitFeatureSize
	Determines whether a minimum feature size is to be used during the design.
bool	LimitMaxNoiseIntensity
	Determines whether stray light intensity is to be limited.
bool	LimitScaleFactor
	Determines whether a lower limit is to be set for the scale factor used during scale freedom.
double	MaxNoiseIntensityLimit
	Maximum relative intensity of the stray light.
double	MinimumFeatureSize
	Minimum allowed feature size.
double	NoiseLimitHighFreq
	Maximum stray light intensity for regions with higher spatial frequencies than those which are allowed by feature size limitation.
int	NumberOfQuantizationLevels
	Number of equidistant phase quantization levels. Only used if the TransmissionType is either "Quantized Phase-Only" or "Quantized Amplitude-Only".
int	PixelationFactor
	Pixelation factor
double	PropagationDistance
	Propagation distance or focal length of 2f-setup
PropagationType	PropagationType
	Type of propagation operator to be used.
VectorD	SamplingDistance
	Sampling distance of the transmission function
Vector	SamplingPoints
	Number of sampling points in transmission which are free parameters.
double	ScaleFactorLimitGoalEff
	Lower limit of the scale factor, specified as goal efficiency.
bool	SimulatePixelation
	Determines whether pixelation of the transmission function should be simulated.
TransmissionType	TransmissionType
	Type of transmission function. "Continuous Phase-Only" by default.
double	Wavelength
	Wavelength

Properties
ComplexAmplitudeType	ComplexAmplitudeTypeOut [get]
	The ComplexAmplitudeType (spatial or spectral) of the output field
FieldDimensions	Dimensionality [get]
	Gets the dimensionality of the design problem (two-dimensional or one-dimensional in x- or y-direction).
VectorD	SamplingDistanceIn [get]
	Sampling distance in the input plane
VectorD	SamplingDistanceOut [get, set]
	Sampling distance in output plane (in m or 1/m depending on selected propagation type)
Vector	SamplingPointsOut [get, set]
	Number of Sampling points in output plane
ComplexField	SignalField [get, set]
	The desired output field.
IRegion1D2D	SignalRegion [get, set]
	The optimization region.
bool	SignalRegionEqualSignalField [get]
	Gets whether the optimization region is created from all positions where the current desired output field is not exactly equal to zero. This is the case if the SignalRegion property is null.

void SetSignalFieldAndSignalRegion	(	ComplexField	signalField,
		IRegion1D2D	signalRegion
	)

Sets the desired output field and the optimization region at the same time.
