Hyperspec MV (Machine Vision) 

HYPERSPEC-MV.jpg

A small, lightweight, and affordable hyperspectral imaging sensor for machine vision applications

Machine vision applications require more resolution and clarity than ever, with the ability to provide hundreds of spectral bands of image data in order to grade and qualify everything from foods to recycled plastics.

Hyperspec MV collects 271 spectral bands of image data across the visible-near-infrared (VNIR) range of 400-1000nm. Fast data transfer using CameraLink allows the sensor to communicate rapidly with the computer and downstream robotics.

Headwall can provide a complete turnkey system based around Hyperspec MV that includes illumination, computer, and all applications software necessary.

Headwall’s hyperspectral sensors all use a concentric imager design that features aberration correction technology. Outstanding spatial and spectral resolution, a wide field of view, and high SNR are benefits that set Headwall apart in the field of airborne hyperspectral imaging. A wide field of view with aberration correction means that swath widths are maximized and flight time is minimized. By integrating everything in one package, Headwall’s airborne solution helps save battery life allowing for more time aloft gathering data.

The integrated data-collection system on Nano-Hyperspec has a Gig-E connection that permits quick and easy off-loading of HSI data between flights while synchronized GPS/INS data collection allows for orthorectification during post-processing. For each hyperspectral sensor, Headwall uses its own all-original diffraction gratings for outstanding optical performance. Benefits include high signal-to-noise and low stray light in a small-form-factor instrument with no moving parts. This means a high degree of robustness and environmental stability...key requirements of any airborne solution.
