Abstract: A method of using a light detection system for increasing the accuracy of a precision airdrop is described. Radiation is transmitted to target areas between an airborne vehicle and a dropzone target. Scattered radiation is received from the target areas. Respective wind characteristics are determined from the scattered radiation and a wind velocity map is generated, based on the respective wind characteristics, between the airborne vehicle, and at least the dropzone target. An aerial release point for the precision airdrop is computed based on the generated wind velocity map and a location of the dropzone target.

Abstract: An all fiber optic laser based scanning system for real time terrain mapping under degraded visual conditions is disclosed. A laser output is modulated to achieve a desired pulse width and pulse repetition frequency (PRF) and the modulated signal is amplified. The amplified optical signals are split into N channels that correspond to N elements of an optically phased array that steers light by modulating the phase of light entering and exiting the optical system. By applying a linear phase shift across the beam's wave front, the light propagating along the system's optical axis is steered to an off-axis angle. A real time map of an underlying terrain is accomplished by sweeping the N channel array across the terrain while collecting range information from each scan grid.

Abstract: A transceiver device that includes one or more light sources configured to emit a light beam that includes one or more different wavelengths, and includes a diffractive optical element configured to initiate one or more wavelength specific responses from the light beam to form one or more transmission light beams and to direct the one or more transmission light beams substantially towards a target; and further includes one or more sensor devices configured to receive the one or more transmission light beams and one or more reception light beams that are reflected back from the target. The diffractive optical element (e.g., a holographic element) is used in either a monostatic, bistatic or multistatic design to reduce the required size and/or number of optical elements, lasers and receivers. The transceiver device may be used in a LIDAR system in order to measure air and wind parameters at multiple altitudes.

Abstract: A pulsed fiber laser including fiber preamplifier and power amplifier stages is disclosed. A fiber preamplifier includes first and second preamplifier stages that receive and amplify a seed pulse. A filter isolator placed between the preamplifier stages suppresses noise from the first preamplifier stage. An acoustic optical modulator located in the second preamplifier stage eliminates unwanted wavelengths from the amplified seed pulse received from the first preamplifier stage. The pulsed fiber laser is rugged and lightweight.
