    Abstract: The invention measures the frequency of a heterodyne laser radar (LADAR) system signal in the input cell of a focal plane array (FPA). Embodiments amplify the return signal, and drive it into a counter for a fixed period of time. The frequency is the number of counts divided by the count time. An example design amplifier amplifies the return of a single photon response of an avalanche photodiode with a gain of 100 into a digital signal level at a 200 MHz rate with only 84 μW, demonstrating the feasibility of the approach.

    Abstract: A fiber laser having a thermal controller operatively connected to one or more fiber Bragg gratings is provided. The thermal controller does not impart much or imparts very little mechanical stress or strain to the optical fiber in which the FBGs reside because such forces can alter the FBG performance. Rather, the thermal controller utilizes a thermally conductive semi-solid or non-Newtonian fluid to submerge/suspend a portion of the optical fiber in which FBG resides. Temperature control logic controls whether a thermoelectric heater and cooler should be directed to increase or decrease its temperature. The thermoelectric heater and cooler imparts or removes thermal energy from the FBG to efficiently control its performance without the application of mechanical stress. The fiber laser having a thermal controller generally is able to increase laser output power greater than two times the amount of output power of a similarly fabricated fiber laser free of the thermal controller(s).

    Abstract: A laser range finder (LRF) and an automated method for determining a return laser signal associated with a target thereof are disclosed. In one example embodiment, the LRF includes a laser beam emitter to emit a laser beam towards a target. Further, the LRF includes a receiver circuit to receive multiple return laser signals reflected from objects including the target and to determine an amplitude of each of the multiple return laser signals. Furthermore, the LRF includes a processor coupled to the receiver circuit to compare the amplitude of each of the multiple return laser signals with a range varying threshold that accounts for range and atmospheric losses and to determine one of the multiple return laser signals as being associated with the target based on the comparison.

    Abstract: A scene correlation-based target system and related methods are provided. A reference image depicts a remotely-positioned object having identifiable characteristics, wherein a reference directional vector is established relative to the reference image. A target image of a general vicinity of the remotely-positioned object has an unknown directional vector, the target image having at least a portion of the identifiable characteristics. An inertial measuring unit has a scene correlation system, wherein the scene correlation system matches the portion of the identifiable characteristics of the target image with the identifiable characteristics of the reference image, wherein a slew angle between the reference image and the target image is calculated. A target image directional vector is derived from the calculated slew angle and the reference directional vector.
