Code and data repository for "Design and Implementation of a Snapshot Ptychographic Wavefront Camera Array"

Regarding the data

Each dataset includes:

1. Raw data from the sensor
2. Cropped data surrounding the feature of interest
3. A montage of the cropped data for easy visualization

The raw data was taken using only the center region of the camera's sensor (300 rows, 304 cols). The cropped data was cropped image-by-image by hand using ImageJ.

The images are labelled like: XX_exposure-time-microseconds.png

Where XX is the camera and we also include the exposure time in microseconds used to collect that image, which is different for each camera becauase of the nonuniform efficienicy distribution of the grating. Each exposure time was chosen to get a well-exposed image from each camera, such that the maximum code value was just below 255 (ensuring no overexposed images).

The cameras are indexed XX like [row, col]. For example, in the manuscript, C_1 would be [00] and C_8 would be [2,1].
