Hyperspectral and Multispectral Imaging

Facebook X LinkedIn Email
Hyperspectral and multispectral imaging are increasingly beneficial for a range of applications as diverse as agriculture, health care, and remote sensing.

JAYLOND COTTEN-MARTIN, EDMUND OPTICS INC.

Over the past two decades, hyperspectral imaging (HSI) and multispectral imaging (MSI) have been growing in prominence and utility. Although the terms are often conflated, they represent two distinct imaging practices, each fitting its own application spaces. Both technologies present advantages over standard machine vision imaging, which uses light only from the visible spectrum. However, with the benefits of HSI and MSI comes increased complexity of the imaging systems in terms of lighting, filtering, and optical designs. Hyperspectral and multispectral imaging are used in...Read full article

    hyperspectral imaging
    Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few spectral bands (such as red, green, and blue in visible light), hyperspectral imaging collects data in numerous contiguous bands, covering a wide range of wavelengths. This extended spectral coverage enables detailed analysis and characterization of materials based on their spectral signatures. Key...
    multispectral imaging
    Multispectral imaging is a technique that involves capturing and analyzing images at multiple discrete spectral bands within the electromagnetic spectrum. Unlike hyperspectral imaging, which acquires data across a continuous range of wavelengths, multispectral imaging is characterized by capturing information at several specific, predefined bands. This allows for the extraction of spectral signatures and information from different parts of the spectrum. Key aspects of multispectral imaging...
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
