X-ray light-field - Small branch - 1 deg angular range

X-ray light-field of a small branch, taken with the FleX-ray scanner, in the Computational Imaging group of CWI (Amsterdam). Angular range is ~1 degree, panel pixel size ~150 um. This bundle includes: <pre><code>light-field_corrected.vox</code></pre> Light-field in the VOX v0 data format (based on HDF5). Any HDF5 reader can open it. Native support is available here: https://github.com/cicwi/plenoptomos. The image floating point precision is FP32. <pre><code>light-field_acquisition_rawdata.tbz </code></pre> Light-field acquisition raw data, archived with Tar and Bzip2. It contains TIF images as projections, dark-field and flat-field. The ini and txt files provide information about the scan (motor positions, etc). <pre><code>tomo_acquisition_rawdata.tbz</code></pre> Tomographic acquisition raw data, archived with Tar and Bzip2. It contains TIF images as projections, dark-field and flat-field. The ini and txt files provide information about the scan (motor positions, angles, etc). <pre><code>tomo_reconstruction_and_segmentation.h5</code></pre> Tomographic reconstruction of the raw data, in HDF5. Any HDF5 reader can open it. It contains two self-descriptive datasets: "volume" and "segmentation".本数据集为使用FleX-ray扫描仪采集的小型树枝的X射线光场（X-ray light-field），数据采集自阿姆斯特丹CWI的计算成像组。该数据集的角采集范围约为1度，平板探测器像素尺寸约为150微米。 本数据集包含以下文件： 1. `light-field_corrected.vox`：采用基于HDF5的VOX v0数据格式存储的光场数据，任意HDF5阅读器均可打开该文件，原生支持库的访问地址为：https://github.com/cicwi/plenoptomos，图像浮点精度为FP32。 2. `light-field_acquisition_rawdata.tbz`：光场采集原始数据，经Tar与Bzip2打包归档，其中包含作为投影、暗场与平场的TIF图像，附带的ini与txt文件提供扫描相关信息（如电机位置等）。 3. `tomo_acquisition_rawdata.tbz`：断层扫描采集原始数据，经Tar与Bzip2打包归档，其中包含作为投影、暗场与平场的TIF图像，附带的ini与txt文件提供扫描相关信息（如电机位置、扫描角度等）。 4. `tomo_reconstruction_and_segmentation.h5`：原始数据的断层重建结果，采用HDF5格式存储，任意HDF5阅读器均可打开该文件，其中包含两个自描述数据集："volume"与"segmentation"。
