Getting started

• Basics of nrefocus
• Setting the NDArray Backend
  • Controlling the ndarray backend
  • Example use of ‘cupy’ backend for Field Refocussing
• 3D stacks
• Input and Output Domains
  • Default: spatial input, spatial output
  • Fourier input: skip the forward FFT
  • Fourier output: skip the inverse FFT
  • Combining both: no transforms at all
