Falak, Przemyslaw Ludwik and Ho-Tin Chan, Justin (2024) Dataset to support the publication "An ultra-compact metasurface and specklemeter based chromatic confocal sensor". University of Southampton doi:10.5258/SOTON/D2853 [Dataset]
Abstract
This dataset is supporting the publication "An ultra-compact metasurface and specklemeter based chromatic confocal sensor" by Przemyslaw Falak et al, in IEEE Transactions on Instrumentation and Measurement This dataset contains one archived file .zip with the following content: 1) This README.txt file, 2) File "Distance_reconstruction.fig" 3) File "Distance_reconstruction.png" 4) File "PCA_values.fig" 5) File "PCA_values.png" 6) File "Reconstruction_error.fig" 7) File "Reconstruction_error.png" 8) File "Metalens_spectradata.mat" 9) File "Metalens_spectradata.png" The raw data was collected as speckle patterns captured by CMOS IMX219 camera Raspberry Pi V2 NoIR (.png files) and further processed by MATLAB scripts. All files were created in MATLAB R2021a and shall be opened by any MATLAB version, starting from R2014b. Alternatively, the files are provided as .png (image) for a preview, but the data underlying these cannot be recovered, unless .fig files are used.
