Structured Light Patterns

This folder contains raw experimental images of structured light patterns, together with the corresponding labels.

`fixed_order_intense.h5` contains images of intense mixed states contained in the entire space of fixed order modes, together with the corresponding density matrix. A mode converter of angle pi/6 was used in this case.

`positive_l.h5` contains images of intense mixed states contained in the space fixed order, positive topological charge modes, together with the corresponding density matrix.

`blade.h5` and `iris.h5` contains image of two dimensional fixed order, positive topological charge modes that are obstructed by a blade and an iris, respectively. The density matrices are also included.

The folder `Photocount` contains photocount distributions of pure states contained in the entire space of fixed order modes, together with the corresponding density matrix. A mode converter of angle pi/2 was used in this case. They are saved in TIFF format. 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.

For examples on how to read the files, check the repository (structured_light_tomography)[https://github.com/marcsgil/structured_light_tomography] and the files in the Tomography folder.
