Structured Light Patterns

This folder contains experimental images of structured light patterns, together with the corresponding labels. There are two intense results which are saved in HDF5 format: `mixed_intense.h5` contains images of mixed states, together with the corresponding density matrix. A mode converter of angle -pi/6 was used in this case. `pure_intense.h5` contains images of pure states, together with the corresponding superposition coefficients. A mode converter of angle pi/2 was used in this case. The photocount results are saved in TIFF format. As, in this case, all states are pure, a pi/2 mode converter was used. Each file contains 2000 frames of a single state, including the file containing the background measurement. One exception is the calibration file, which contains a single intense frame of a Gaussian with the same waist and center as the produced modes. The coefficients of the superposition are saved in the file `coefficients.h5`. Only the first 50 coefficients are used.
