HYPER-SPECTRAL IMAGING USING SPATIALLY-MODULATED ILLUMINATION

这个子项目是许多利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 该项目是调制成像核心项目的合作。它旨在将联合收割机计算机断层成像光谱（CTIS）与空间调制照明相结合。计算机断层成像光谱技术是一种快速的高光谱技术，它允许用单个CCD帧采集进行高光谱2D成像。这种技术是基于使用一个二维光谱分散器，用于投影一个对象的几个图像上的大型大型成像阵列。单个图像包含所有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成像算法重建而获得的，因此该技术被称为层析成像。高光谱图像的重建是使用一个校准矩阵，这是测量和计算完成。

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.
