Active imaging techniques can provide increased signal-to-noise ratio over passive imaging
approaches, particularly in the reflective infrared bands (NIR, SWIR, and eSWIR) where …

Active imaging techniques such as continuous-wave (CW) illumination and laser range-
gated (LRG) imagery can provide increased contrast-to-noise ratio over passively …

The sensitivity of active targeting systems in the shortwave infrared band is currently limited
by high read noise associated with conventional readout integrated circuitry. This limit …

Coherent illumination of an optically rough surface creates random phase variations in the
reflected electric field. Free-space propagation converts these phase variations into …

Range-gated imaging has the advantages of long imaging distance, high signal-to-noise
ratio, and good environmental adaptability. However, conventional range-gated imaging …

Targeting is a vital function of any weapon system, providing visual information about
targets, determining whether those targets are of interest, and helping to track the target for …

Collecting sufficient photon flux to clearly observe a target against the background and
sensor noise is critical for long-range target imaging. The sensitivity can be characterized by …
