  • Multispectral Camera
May 2012
JAI Inc.Request Info
SAN JOSE, Calif., May 30, 2012 — JAI Inc. has released the AD-130GE, a two-CCD multispectral camera offering high resolution and good light sensitivity. It incorporates a dichroic prism to provide simultaneous capture of both color and near-infrared digital video on a single optical path for efficient multispectral inspection and analysis.

The camera produces 1296 × 966-pixel resolution. Using two precisely aligned ?-in. Sony ICX447 CCDs, it operates at 31 fps.

The camera’s sensitivity to visible light is ~20% greater than that of the company’s AD-080 models, while NIR sensitivity is more than twice that of its predecessors. This leads to higher quality images under typical conditions, with less illumination needed to produce proper signal-to-noise ratios for inspection tasks.

Analysis of multiple images taken using different wavelengths of light has been used in a variety of industries to examine properties including color, size and printing, as well as nonvisible elements such as bruises, scratches and moisture content. But traditional two-camera solutions are costly and difficult to calibrate.

The company’s two-CCD technology provides a single-camera approach to this challenge that enables multispectral analysis for a wide range of inspection tasks. Typical uses include inspection of fruits and vegetables, blister packs or other plastic film containers, and medical supplies where the two channels can be used to check the integrity of both inner and outer seals on plastic pouches and bags.

Output is via two GigE interfaces on the back of the camera. Color output is available in raw Bayer form (8, 10 or 12 bit) for host-based interpolation, or as 24- or 30-bit RGB. NIR output is user-selectable 8-, 10- or 12-bit monochrome images.

Camera features include multiple shutter modes (including auto shutter), a configurable general-purpose input/output module, look-up tables for gamma customization, manual or automatic gain control, and analog video.
