The AD-081GE is a unique prism-based 2CCD camera, incorporating two monochrome CCD sensors (ICX204AL) with sensitivity in the visible spectrum. The prism-based design enables a single optical path to be split across both CCDs simultaneously while maintaining alignment to within one-quarter pixel.

By altering the shutter/gain settings of the two CCDs and fusing the two synchronized video streams, the AD 081GE can provide more than double the dynamic range of standard CCD cameras (up to ~120 dB) but in a linear fashion that avoids the noise, shutter, and compression issues found in typical CMOS-based logarithmic or LinLog™ high dynamic range cameras.

Alternatively, the timing of each CCD's readout can be offset by one-half frame and interleaved together to produce 60 fps output without the image degradation that would result from over-clocking the CCDs.

The AD081GE is equipped with continuous mode, pre-select trigger mode, pulse width trigger mode and a special 3-shot PIV (Particle Image Velocimetry) mode (download PIV technical note for more details).

Output is via a standard GigE Vision interface, which can be used in a one-cable or two-cable configuration, depending on the mode used.

Typical HDR applications for the AD-081GE include inspection tasks where incident light or bright reflections are present, such as LED inspection, welding, and various types of lighting or glass inspections. The camera is also ideal for a wide range of automotive applications, microscopy, or high-end surveillance uses. The parameters of each CCD can be adjusted by the user to provide maximum dynamic range or maximum contrast/sensitivity within a narrower lighting range, depending on the application.
