92 KHz SWIR digital line scan camera for spectral-domain optical coherence tomography

June 7, 2010
The SU1024LDH2 digital line scan SWIR indium gallium arsenide (InGaAs) camera from Sensors Unlimited - Goodrich ISR Systems features an increased line rate to over 91,900 lines per second for spectral-domain optical coherence tomography (SD-OCT) imaging applications to detect moisture, lipids, proteins, or other molecular vibration absorbance bands in the 800-1700 nm range. 

The SU1024LDH2 digital line scan SWIR indium gallium arsenide (InGaAs) camera from Sensors Unlimited - Goodrich ISR Systems features an increased line rate to over 91,900 lines per second for spectral-domain optical coherence tomography (SD-OCT) imaging applications to detect moisture, lipids, proteins, or other molecular vibration absorbance bands in the 800-1700 nm range. In the 1.05 µm wavelength band, the imager can capture detailed 3D SD-OCT volumes of the retina, choroidal vasculature and nerve head. A compact (3 × 3 × 2.4 in.) camera housing features both metric and SAE mounting holes on multiple sides for configuration into existing systems or for other positioning purposes. Wavelength response ranges from over 0.8 to 1.7 µm with a 25-µm pixel pitch and aperture heights of 25 µm or 500 µm. Additional features include integrate-while-read snapshot acquisition and operator-selectable trigger modes: single line per trigger, programmable exposure, or gated burst.
