A continuous-face-sheet Xinetics deformable mirror (DM) is characterized and analyzed using Fizeau interferometer measurements. The influence of each individual actuator on the DM surface is measured. The measured data is then processed to be used as

The FITTS correlation algorithm has been widely used for over forty years in high speed video trackers. It has the advantage that it is very simple implement in a digital processor with a small number of calculations. At each step the algorithm attem

Laser illuminated imaging has a number of applications in the areas of night time air-to-ground target surveillance, ID, and pointing and tracking. Using a laser illuminator, the illumination intensity and thus the signal to noise ratio can be contro

Micromachined electrostatic membrane mirrors have been in use for several years in active and adaptive optics applications. We introduce a deformable mirror with small static aberrations and resistant to damage during electrostatic snap-down in an ar

We present here results of laboratory and field experiments using the OKO technologies membrane mirror as an adaptive optics device. The device can be operated at high temporal bandwidths from a low cost PC based control system. We have constructed a

It is well known that atmospheric turbulence corrupts the phase front of laser beam propagation. The phase distortions manifest themselves as intensity fluctuations when the beam is propagated over some distance. This intensity fluctuation is often r

Recent advances in InGaAs camera technology has stimulated interest in the short wave infra-red (SWIR) band in the spectral region 0.84 – 1.7 μm. Located between the visible and thermal infra-red, the SWIR band shows interesting properties of both

Laser aided detection and ranging (LADAR) imaging systems are usually corrupted by several pathologic noises. Speckle noise is due to the coherent nature of the laser illuminator. Scintillation noise is introduced by atmospheric turbulence over the o
