IR Spectrometers

IR Spectrometers

There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

Super-resolution Fluorescence Microscopy

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Background:

Traditional pushbroom spectral imaging methods face limitations in simultaneously improving spatial and spectral resolution due to constant incident light energy.
Improving one resolution parameter often leads to sacrificing the other, hindering the acquisition of high-quality spectral data.

Purpose of the Study:

To propose a new spectral imaging method, coded dispersion, for obtaining high-resolution (HR) spectral images.
To overcome the limitations of conventional methods by enabling HR spectral image acquisition with low-resolution detector arrays.

Main Methods:

The proposed method, coded dispersion, utilizes compressive measurement principles.
It enhances light collection efficiency, allowing for high-quality reconstructed HR spectral images.
The technique enables acquisition with fewer sensors compared to traditional approaches.

Main Results:

Simulation results demonstrate the effectiveness of the coded dispersion method.
The method successfully reconstructs high-quality HR spectral images.
It offers a viable solution for spectral imaging under constraints such as detector array density.

Conclusions:

Coded dispersion presents a novel approach to spectral imaging, enhancing both spatial and spectral resolution.
The method is particularly advantageous when detector array density is limited by factors like battery, capacity, transmission bandwidth, and cost.
Leveraging prior knowledge of scenes further enhances the capabilities of this HR spectral imaging technique.
