Transport Properties of Divertor Edge Plasmas Measured with Multi-Spectral Imaging
… and inflexible spatial coverage. In this thesis, multi-spectral imaging of helium line ratios (HeMSI) was used to create 2D poloidal maps of Tₑ and nₑ in the TCV divertor. These are the first plasma boundary measurements to provide continuous 2D coverage of Tₑ and nₑ for arbitrary magnetic …

Bio-Inspired Multi-Spectral Imaging Sensors and Algorithms for Image Guided Surgery
<p>Image guided surgery (IGS) utilizes emerging imaging technologies to provide additional structural and functional information to the physician in clinical settings. This additional visual information can help physicians delineate cancerous tissue during resection as well as avoid damage to …

Real-Time Nitrogen Detection System of Corn Crop Using a Multi -Spectral Imaging Sensor
Real-time N-deficiency was estimated by using NDVI and mapped relative to unstressed healthy plants. The MSIS system provided a measure of crop response that correlated with plant SPAD measurements (-0.93 for G channel and -0.88 for R channel). The system had smaller measurement variation than the …

Ground Sensor Based Variable Rate Nitrogen Management
Integrating the multi-spectral imaging sensor with a variable-rate nitrogen application system, can provide the fundamental means for performing site-specific variable-rate nitrogen side-dressing applications. Using the estimated SPAD values to support sensor-based variable rate nitrogen …

Spectral studies of small-scale auroral structure and plasma instability in the high-latitude ionosphere
… driven by low-energy electron streams. Using multi-spectral imaging in combination with radar observations, a direct link is shown between ion-acoustic wave enhancements and precipitating electrons at 100 eV energies. Wave enhancements at the radar wavevector which are three orders of …

New Tools for Real-Time Study of Embryonic Development
… Conventional assays and fluorescence-based imaging methods have been widely used for the study of embryonic development. These conventional methods cannot effectively provide spatial and temporal resolutions with sufficient sensitivity and selectivity that are required to depict embryonic …

Multi-spectral light interaction modeling and imaging of skin lesions
… of monochromatic light in the trans-illumination imaging using the Nevoscope can be used to obtain this information. Optimal selection of wavelengths for multi-spectral imaging requires light-tissue interaction modeling. For this, three-dimensional wavelength dependent voxel-based models of skin …

Quantifying the Diversity of Agronomic Traits of Cicer Milkvetch (Astragalus cicer L.) Germplasm Collections Using UAV-Based Imagery
… from June to mid-October using UAV-based multispectral imaging, and 3) Identify UAV-based traits with significant correlations to the forage DMY and growth of cicer milkvetch. Near Clavet Saskatchewan, a completely randomized nursery of 27 cicer milkvetch populations was characterized nine …
