A system and method for simulating realistically sized emission signature of a weapon system or weapon platform for the purpose of testing an optical detection device at a long distance in the field. The system utilizes an image screen with a curved imaging surface that is positioned at least one kilometer away from the optical detection device being tested for example. The optical testing device observes the image screen through ambient environmental conditions. A projection device is provided at a first distance from the image screen. The projection device projects a simulation of the emission signature onto the curved imaging surface. The curved imaging surface reflects the simulation toward the optical detection device. A focusing system can be used to adjust the reflection so that the simulation is collimated, converging or dispersing as it progresses toward the optical detection device.

System, method and device for a long range, real size weapon systems plume simulator for testing optical detection devices in the field

A system, method, and device for simulating an emission signature, which contains representative intensity, temporal, and spectral emission profiles of a weapon system or weapon platform for the purpose of testing an optical detection device. A projection system optically projects the emission signature. A projection screen is provided that has a concave curvature. The concave curvature possesses a first focal point and a second focal point. Any light emanating from the second focal toward the projection screen is reflected by the projection screen toward the first focal point. The projection system is positioned at the second focal point and the optical detection system is positioned at the first focal point. In this manner, the emission signature projected by the projector system is redirected to the optical detection system.

System, method and device for a high fidelity electro-optical simulator

A diode laser beam combining apparatus for producing a high combined beam power density in the far field at reduced levels of power consumption and heat dissipation includes an array of semiconductor laser emitters arranged in a collinear manner with respect to each other and having an emitter pitch between about 0.7 mm and 2.5 mm. The apparatus also includes a cylindrical lens for collimating emitter beams generated by the array of laser emitters in a direction perpendicular to a junction plane of the laser emitters. The apparatus further includes a micro-optic array and a long focal length cylindrical lens. The micro-optic array is configured to perform a rotational transformation of the collimated emitter beams. The micro-optic array has a lateral spacing in a direction parallel to the junction plane of the laser emitters that matches the emitter pitch. The long focal length cylindrical lens collimates emitter beams in the direction perpendicular to the junction plane after passing through the micro-optic array.
