IR Spectrometers

3.1K
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...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

1.1K
Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy  (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

    Summary

    We developed spectrally dispersed illumination spectral imaging (SDISI) for faster, higher-resolution spectral imaging. This technique improves signal-to-noise ratios (SNRs) for biomedical applications, even with sensitive specimens.

    Area of Science:

    • Biomedical Optics
    • Spectral Imaging Technology
    • High-Speed Imaging Systems

    Background:

    • Spectral imaging offers valuable insights but is often limited by low imaging rates and signal-to-noise ratios (SNRs).
    • Biomedical applications frequently require fast imaging to prevent motion artifacts and accommodate specimens sensitive to high illumination intensities.
    • Existing spectral imaging methods struggle to balance speed, resolution, and data quality.

    Purpose of the Study:

    • To introduce a novel spectral imaging technique, spectrally dispersed illumination spectral imaging (SDISI), designed to overcome the limitations of conventional methods.
    • To enable high-speed, high-resolution acquisition of spectral data for challenging biomedical applications.
    • To demonstrate the efficacy of SDISI in capturing detailed spectral information from biological samples.
