Linear variable optical filter-based ultraviolet microspectrometer.
An IC-compatible linear variable optical filter (LVOF) for application in the UV spectral range between 310 and 400 nm has been fabricated using resist reflow and an optimized dry-etching. The LVOF is mounted on the top of a commercially available CMOS camera to result in a UV microspectrometer. A special calibration technique has been employed that is based on an initial spectral measurement o...
متن کاملStatic Hyperspectral Fluorescence Imaging of Viscous Materials Based on a Linear Variable Filter Spectrometer
This paper presents a low-cost hyperspectral measurement setup in a new application based on fluorescence detection in the visible (Vis) wavelength range. The aim of the setup is to take hyperspectral fluorescence images of viscous materials. Based on these images, fluorescent and non-fluorescent impurities in the viscous materials can be detected. For the illumination of the measurement object...
متن کاملHyperspectral Imaging for Diffuse Optical Tomography
Diffuse optical tomography (DOT) has emerged in the last decade as a new and exciting tool for functional medical imaging with applications in a range of areas including breast cancer detection and diagnosis. DOT employs observations of near infrared (NIR) light that has propagated through tissue to reconstruct the spatial distribution of various chromophores present in the region of interest. ...
متن کاملOptical Filter Design of Fluorescence Imaging System Using Linear Disciriminant Analysis
Based on a fluorescence imaging model, the optical filters, such as excitation and emission filters, are determined by linear discriminant analysis. The discriminability is a quadratic Rayleigh quotient of one filter if the other filter is assumed to be constant. The optical filters are optimized alternatingly and iteratively by solving their generalized eigenvalue problems. The proposed method...
