    A new pushbroom imager for forestry remote sensing was developed. This high-resolution sensor achieved 25 cm pixel sizes, enabling detailed mapping applications.

    Area of Science:

    • Remote Sensing
    • Optical Engineering

    Background:

    • Forestry and mapping applications require high-resolution aerial imagery.
    • Existing remote sensing technologies may have limitations in spatial detail.

    Purpose of the Study:

    • To develop a prototype pushbroom imager for forestry remote sensing and mapping.
    • To achieve high spatial resolution for detailed aerial data acquisition.

    Main Methods:

    • Development of a single-channel push broom imager.
    • Utilized a commercial 6000-element linear array.
    • Designed and fabricated a custom wide-angle, high modulation transfer function lens.
    • Tested the imager aboard a twin-engine jet aircraft.

    Main Results:
