Compact camera for multispectral and conventional imaging based on patterned filters
(2014)
A multispectral camera concept is presented. The concept is based on using a patterned filter in the focal plane, combined with scanning of the field of view. The filter layout has stripes of different bandpass filters ...
Turbulence characterization and image processing data sets from a NATO RTO SET 165 trial in Dayton, Ohio, USA
(2012)
The performance of optical systems is degraded by atmospheric turbulence. Over propagation distances that exceed several kilometers, it is difficult to evaluate its impact because of terrain variability - a factor that ...
Characterization of a compact 6-band multifunctional camera based on patterned spectral filters in the focal plane
(2014)
In some applications of multi- or hyperspectral imaging, it is important to have a compact sensor. The most compact spectral imaging sensors are based on spectral filtering in the focal plane. For hyperspectral imaging, ...
Laser beam propagation through turbulence and adaptive optics for beam delivery improvement
(2015-10-08)
We report results from numerical simulations of laser beam propagation through atmospheric turbulence. In particular, we study the statistical variations of the fractional beam energy hitting inside an optical aperture ...
