Field Imaging

In terahertz imaging systems based on Gaussian beam active illumination and focal plane array detectors, severe image distortion has been observed, which significantly reduces the resolving power of the imaging system. To solve this problem, a novel computational method, Light Field Imaging (LFI), has been introduced for terahertz imaging. A conventional transmission-type terahertz imaging system based on a gas-pumped terahertz source and terahertz Focal Plane Array Detectors (FPA) arrays is established to analyze the problem of image distortion. An experimental virtual camera array terahertz LFI system is also established. With the acquisition and reconstruction of synthetic aperture terahertz light fields, the improvement on resolving power and SNR performance have been validated.

Cotton maturity describes the thickness of the cotton secondary cell wall. There is a need for developing non-destructive methods for measuring maturity that also examine distribution. The current study seeks to expand reported infrared (IR)-based maturity determinations using an IR imaging system with a focal-plane array (FPA) detector. Adapted equations were used to examine the maturity of cotton standards and of a larger set of upland cotton varieties (30 total). Maturity values obtained with a Cottonscope and from IR determinations showed strong linearity, R2 = 0.95, while contour plots provided a visual representation of the maturity distribution in the samples. These results validate the use of IR measurement for examining cotton maturity and establish the use of the FPA IR system for examining and imaging cotton maturity distributions.
