Detailed Description

This class provides a deconvolution filter which sharpens peaks back to their original optical resolution by removing the Gaussian blur point-spread function.

This class is responsible for the "[x] Sharpen Peaks" checkbox on the KnowItAll settings.

Member Function Documentation

◆ change_axis_callback()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.change_axis_callback	(	self,
		old_axis,
		new_axis )

◆ generate_gaussian()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.generate_gaussian	(	self,
		spec,
		unit )

◆ get_gaussian()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.get_gaussian	(		self,
			spec )

There are various ways we could decide what unit to use for average FWHM.

We could just use whatever was currently displayed on-screen (graph.get_x_axis_unit), but the on-screen x-asis is essentially irrelevant to the calculation. Since this feature is basically being provided for Raman, let's just say use wavenumbers for Raman models – regardless of whether the laser is engaged, or we're looking at an emission source (like we'd know) – and wavelengths otherwise.

◆ is_supported()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.is_supported	(		self,
			spec )

◆ process()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.process	(	self,
		pr,
		spec )

Parameters

pr	(In/Out) ProcessedReading
spec	(Input) Spectrometer

See also: Dieter for algorithm explanation

Note: supports cropped ProcessedReading if available

◆ reset()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.reset ( self )

Generating the Gaussian is somewhat intensive, so cache it.

However, when an input to the Guassian changes (like the user has changed the ROI), flush so it will be regenerated.

◆ update_from_config()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.update_from_config ( self )

◆ update_from_gui()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.update_from_gui ( self )

◆ update_visibility()

enlighten.post_processing.RichardsonLucy.RichardsonLucy.update_visibility	(		self,
			spec = None )
