White Paper: Expanding The Dynamic Range Of Short Wave Infrared (SWIR) Imagery
1/22/2010
Advances have been made in short wave infrared (SWIR) imaging technology to address the most demanding imaging and surveillance applications. Multiple techniques have been developed and deployed in Goodrich’s SWIR indium gallium arsenide (InGaAs) cameras to increase the dynamic range performance of standard, commercial off-theshelf (COTS) products.

Application Note: SWIR Imaging In Solar Cell Inspection
12/29/2009
Solar cells are large-area semiconductor devices with typical dimensions of 15 cm. Loss mechanisms such as locally reduced diffusion lenghts or parallel resistances often reduce the energy conversion efficiency of solar cells. Characterization techniques that can provide spatially resolved information about the performance of a solar cell therefore are important to manufacturers not only in research and development but also in solar cell production.

Application Note: Cheetah-640CL For High Speed Imaging In SWIR
12/29/2009
The laser beams used for free-space satellite communication emit typically at 1060 nm or 1550 nm (eye-safe and low atmospheric attenuation). In reduced region of interest mode of, e.g., 100 x 100 pixels, the Cheetah camera can achieve well over 10.000 fps. This feature of the camera is being used in adaptive optics systems to correct imaging systems for atmosphere turbulence. The high speed Cheetah camera, mounted behind a Shack-Hartmann sensor to measure the wave distortion, provides active feedback to the deformable telescope mirror in order to have a corrected wavefront on the highspeed demodulator.
