Applications on the Upswing as Cost of Imaging Systems Come Down

Facebook X LinkedIn Email
From picking the juiciest and most colorful cranberries for consumption to detecting one of the most elusive of cancers — brain cancer — imaging systems are gathering momentum, largely thanks to shrinking size and cost.

MARIE FREEBODY, CONTRIBUTING EDITOR, [email protected]

Every autumn — usually from mid-September until around mid-November in North America and March through May in South America — cranberries reach their peak of color and flavor and are ready for harvesting. It’s then the turn of hyperspectral imagers to ensure only the best grade cranberries make it through to production from the millions of kilos that are harvested. In March 2015, spectral-imaging specialist Headwall Photonics Inc., based in Massachusetts, began a collaboration with a well-known cranberry-products maker to begin testing new spectral-imaging/machine...Read full article

    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
    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...
    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...
    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
