A Wide Spectral Range Reflectance and Luminescence Imaging System
In this study, we introduce a wide spectral range (200-2500 nm) imaging system with a 250 μm minimum spatial resolution, which can be freely modified for a wide range of resolutions and measurement geometries. The system has been tested for reflectance and luminescence measurements, but can also be customized for transmittance measurements. This study includes the performance results of the dev...
متن کاملWide-range thermochromic luminescence of organoboronium complexes.
Alkyl-substituted tetra-coordinate organoboronium bisdiketone complexes exhibit dramatic luminescence thermochromism in organic solvents. In glass-forming alcohols, these complexes exhibit a reversible aqua blue to orange-red to greenish yellow luminescence emission colour change upon cooling.
متن کاملA Spectral Color Imaging System for Estimating Spectral Reflectance of Paint
In this paper, the analysis methods used for developing imaging systems estimating the spectral reflectance are considered. The system incorporates the estimation technique for the spectral reflectance. Several traditional and machine learning estimation techniques are compared for this purpose. The accuracy of spectral estimation with this system and each estimation technique is evaluated and ...
متن کاملA Wide Dynamic Range Multichannel Spectral Estimator
A multichannel extension of the AR matrix prewhitened power spectral density estimator, which was originally developed for a single channel, is proposed. In order to make the extension, the Cholesky decomposition of the inverse autocorrelation matrix for a multichannel autoregressive process is discussed and the autoregressive model order selection for a multichannel process based on the expone...
متن کاملWide dynamic range imaging
Interest in technologies that can help improve image sensors—in terms of cost, noise and dynamic range—is growing as quickly as the market for them. Dynamic range (DR) quantifies the ability of a sensor to image highlights and shadows. If we define the dynamic range of the sensor as 20 log(S/N), where S is the maximal signal value and N is the sensor noise, the typical image sensors will have a...
