A system (10) for testing a laser proximity fuse (PF) (12) by simulating a closing velocity to a target along a line of sight (14) includes a static spiral surface (16) and a support arrangement (18) for supporting the proximity fuse (12) with the line of sight (14) directed towards an inside of static spiral surface (16). A folding mirror (20) is driven by a drive motor (22) so as to deflect the line of sight (14) towards progressively closer regions of static spiral surface, thereby simulating a closing velocity. The system can be miniaturized by employing converging optics (24). An alternative embodiment employs a shaped rotor (32) to achieve a similar effect.

A laser imaging system is disclosed for generating an image of a target. The system includes a laser seeder for generating a laser beam. The beam is split into two beams, with one being sent to a CBC unit and the other to a reference unit. Both beams are broadened and the beam sent to the CBC unit is split into multiple beamlets which are transmitted to the target. A distance and velocity determination unit measures the distance to the target and the beam sent to the reference unit is delayed by a round trip period corresponding to the distance. The beam returned from the target is interfered with the broadened and delayed reference beam. An electrical signal corresponding to the combined beam is generated and used to phase lock all the CBC transmitted beams on the target and to construct an image of the target.

Each actuator has two interconnected beams (12a, 12b) from a first material and a rod (18) associated with the ends of both beams such that a distance between the ends is determined by a length of the rod. The rod is formed from a second material having a coefficient of thermal expansion different from that of the first material such that a variation in temperature causes deformation of the actuators, thereby varying a height of the actuators according to an effective coefficient of thermal expansion with a magnitude greater than that of both materials. This adjusts a relative position of the first and second components along the optical axis.

A coherence reconstruction apparatus generates measurements of atmospheric turbulence from light reflected by a target. The apparatus is in communication with a coherent beam combining (CBC) system which illuminates a target with one or more partially coherent beams from a seed laser. The apparatus includes a variable delay module and a phase shift interferometer (PSI). The delay module uses a measurement of target time-of-flight to form a coherent delayed reference signal from the CBC seed reference laser. The delay module may incorporate an electromagnetically induced transparency medium and/or an electro-optical modulator. The PSI combines the delayed reference optical signal with a target-reflected optical signal to form an interference pattern and to determine one or more turbulence phase correction measurements. The apparatus may include a controller for generating feedback and dynamic tuning signals.
A system for illuminating a target in the presence of atmospheric turbulence includes a coherent beam combining (CBC) subsystem, an atmospheric wave-front sensor (AWS) subsystem, a multi-channel photo-detector (MCPD) subsystem, an auxiliary light source, and a receiving optical aperture. The CBC subsystem forms a multiplicity of CBC sub-beams and an reference beam, all of which fall in a wavelength band that is different from that of the auxiliary light source. The auxiliary light source may be a laser or a portion of the solar spectrum of the Sun. An AWS controller provides closed-loop compensation of atmospheric turbulence for low power auxiliary reflection and reference beams. A MCPD controller provides closed-loop compensation of high-frequency laser noise and transfers the wavefront correction from the reference to the high power CBC laser. The frequency of the MCPD controller is at least an order of magnitude greater than the bandwidth of the AWS controller.

MULTIPLE COHERENT BEAM COMBINATION SYSTEMS SHARING A COMMON RECEIVER
A targeting receiver operates with beam emitters. Each emitter generates coherent beams directed towards a target as a composite beam having an associated signature. For each composite beam, the target reflects a proportion of radiation intensity as a reflected radiation component. A receiver telescope collects target-reflected radiation and directs the radiation to a spatial filter. The reflected radiation includes radiation components, at least some of which are combined as a combined radiation composed of the reflected radiation components. Intensity of the combined radiation indicates the intensity of the composite beams impinging on the target. The spatial filter filters the reflected radiation by selectively passing the combined radiation. Each component of the combined radiation is identifiable by the signature associated with the composite beam corresponding to the component of the combined radiation. In certain embodiments, a distinguishing module is associated with the receiver and distinguishes the components based on the signature.

MULTIPLE COHERENT BEAM COMBINATION SYSTEMS SHARING A COMMON RECEIVER
A targeting receiver operates with beam emitters. Each emitter generates coherent beams directed towards a target as a composite beam having an associated signature. For each composite beam, the target reflects a proportion of radiation intensity as a reflected radiation component. A receiver telescope collects target-reflected radiation and directs the radiation to a spatial filter. The reflected radiation includes radiation components, at least some of which are combined as a combined radiation composed of the reflected radiation components. Intensity of the combined radiation indicates the intensity of the composite beams impinging on the target. The spatial filter filters the reflected radiation by selectively passing the combined radiation. Each component of the combined radiation is identifiable by the signature associated with the composite beam corresponding to the component of the combined radiation. In certain embodiments, a distinguishing module is associated with the receiver and distinguishes the components based on the signature.

Coherent beam combination (CBC) systems and methods
c) allow adjustment of relative phase offsets of the beams. A detector (16) monitors an intensity of the radiation impinging on an area of the target (T). A controller (18) receives the intensity parameter and controls a phase adjustment of the beams according to a deterministic (i.e., quantitative) measurement of a phase offset of each beam relative to a representative phase of the sum of all the other beams. This is achieved by using interferometric techniques, referred to herein as Target In-the-Loop Interferometry (TILI).
