Examples

These examples walk from a first hyperspectral camera to full end-to-end design. Each corresponds to a script in the repository root.

Build & visualize

Set up the differentiable HSI camera and inspect how each DOE encodes the spectrum into its PSF.

Example	Script	Description
Diffractive Surfaces	0_hello_deeplens_hsi.py	The three DOE encoders — phase maps and wavelength-dependent PSFs

Train & design

Train the reconstruction network — against a fixed encoder, or jointly with the optics.

Example	Script	Description
HSI Reconstruction	1_hsi_reconstruction.py	Train NAFNet to recover the spectral cube from a fixed-DOE capture
End-to-End Design	2_end2end_hsi.py	Jointly optimize the DOE and the reconstruction network
