PSF Type

To perform image deconvolution a Point Spread Function (PSF) is needed.

The Huygens software can compute a theoretical PSF from the image parameters used during deconvolution or it can use a measured PSF.

Depending on the user choice HRM will, at a later stage, ask for:

  • the path to the file containing the PSF if you selected Measured,
  • the settings to correct for spherical aberration if you selected Theoretical and there is a refractive index mismatch.

In most cases a theoretical PSF works fine.
