• gpu_rayleighsommerfeld: Hardware accelerated Rayleigh-Sommerfeld back-propagation using GPULib.

• rs1d: Computes Rayleigh-Sommerfeld back-propagation of a normalized hologram along a specified axial line.

• gpu_rs1d: Hardware-accelerated version of rs1d using GPULib.

• rs_decon: Implementation of Rayleigh-Sommerfeld deconvolution microscopy.
