This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The project is a collaboration for the modulated imaging core project. It is aimed to combine Computed Tomographic Imaging Spectroscopy (CTIS) with spatially modulated illumination. Computed Tomographic Imaging Spectroscopy is a fast hyperspectral technique, that allows for hyperspectral 2D imaging with a single CCD frame acquisition. This technique is based on the use of a two-dimensional spectral disperser that is used to project several images of an object on a large large-format imaging array . A single image contains all of the spectral and spatial image information, so the data can be captured at high rates. The spectral data of the image is obtained by reconstruction using tomographic algorithms, hence the name of the technique . Reconstruction of the hyperspectral images is accomplished using a calibration matrix, which is both measured and computed.

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 该项目是对调制成像核心项目的合作。它的目的是将计算机层析成像光谱分析(CTIS)与空间调制照明相结合。计算机层析成像光谱学是一种快速的高光谱技术，它允许通过一次CCD帧采集来进行高光谱2D成像。这项技术基于二维光谱分散器的使用，该分散器用于将对象的几个图像投影到大型大幅面成像阵列上。一幅图像包含了所有的光谱和空间图像信息，因此可以以高速率捕获数据。图像的光谱数据是通过使用层析算法重建而获得的，因此该技术得名。高光谱图像的重建是使用校准矩阵来完成的，该校准矩阵既被测量又被计算。
