Sensors Unlimited to reveal two InGaAs cameras

One of the cameras is claimed to be the world's fastest 2048 pixel linescan camera. Both devices are designed specifically for spectral-domain optical coherence
UTC Aerospace Systems / Sensors Unlimited Inc. (SUI) will demonstrate what they say is the world’s fastest 2048-pixel Linescan Camera at >145,000 A-lines per second at BIOS and Photonics West.

The SUI GL2048R camera, joins the 76,000 lps GL2048L enabling OEMs and researchers to maximise speed or minimise cost for their Spectral Domain OCT systems (SD-OCT).

The GL2048R and L cameras deliver the high-resolution and high-speed needed for SD-OCT, whether to minimise eye motion artefacts or to scan larger volumes with minimum patient discomfort.

Compact and slim, the GL2048 cameras feature InGaAs photodiode arrays of 2048 pixels with 210 µm height and 10 µm width.

The cameras are ideal for SD-OCT at 1.04 µm for retina diagnostics, 1.31 µm for corneal and cardiovascular imaging, or 1.55 µm for deepest imaging in non-medical OCT applications.

The GL2048L model has been shipping for a year to researchers and OEMs, and with its line rate range from 100 lps is also being used for silicon ingot photoluminescence inspection.

The new Sensors Unlimited GA1280JSX-12.5 snapshot camera is the third megapixel-class InGaAs commercial camera put into production by UTAS since 2011 and will be demonstrated at the show booth. 

Featuring SUI’s unique extended sensitivity pixel design, now in a 12.5 µm pixel pitch, the new camera is ideal for high-definition imaging in varying conditions from low-level light to daylight, and through low-density obscurants.

The light-weight and compact size enables easy integration into aerial, mobile and hand-held surveillance or hyperspectral systems.

What's more, the camera employs on-board Automatic Gain Control (AGC) and built-in non-uniformity corrections (NUCs), allowing it to address the challenges of high-dynamic-range urban night imaging without blooming.

Camera Link digital output provides for plug-and-play video with 12-bit images for digital image processing or transmission.

UTAS / Sensors Unlimited will be showcasing these cameras at booth #8622 at BIOS and #622 at Photonics West and will also be able to describe companion HD models, the GA1280J-15 and the GA1280JS-12.5 cameras, which can be used for high-definition microscope inspection of integrated circuits and MEMs devices.

Also being demonstrated will be the Sensors Unlimited SU640HSX, the very sensitive InGaAs camera for pilot or driver vision enhancement, laser detection, wide area surveillance, imaging through low-density fog, dust or smoke, video-rate nano-tube imaging, photoluminescence and weak electroluminescence, and other low- light applications. 

Providing both analogue EIA-170 video and 12-bit digital video out, the camera uses patented image enhancement and automatic gain control algorithms to produce clear usable video over a very wide range of lighting conditions. 

Developed in 2008, these algorithms have ensured the SU640HSX continues imaging long after competitor’s have packed up their cameras and gone home.
