Multi-spectral camera


JAI has released the AD-130GE, a 2-CCD multi-spectral camera offering significantly greater resolution and light sensitivity than the company's first-generation models. Like the AD-080 series, the AD-130GE incorporates a dichroic prism to provide simultaneous capture of both color and near-infrared digital video on a single optical path for efficient multi-spectral inspection and analysis.

As the model number implies, the AD-130GE provides 1.3 megapixel resolution (1296 x 966 pixels) compared to the 0.8-megapixel resolution of the existing AD-080 series. Using two precisely-aligned 1/3" Sony ICX447 CCDs, the AD-130GE maintains a comparable capture rate to the AD-080 series (31 fps), while taking advantage of increased sensitivity, especially in the NIR portion of the spectrum.

Sensitivity to visible light is approximately 20% greater than the 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.

Output from the AD-130GE is provided 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-bit 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 GPIO module, look-up tables for gamma customization, manual or automatic gain control (AGC), and analog video output to support auto-iris lenses.
