LTB-2 energy dimensional transfer prototype R&D

Energy beam path: LTB-2 energy beam start location - energy beam not perceptible in airspace path - energy beam appearing at a local target.

The dimensional energy beam is an energy that can eliminate the discharge spark (experimentally proven) and laser light from the local space, if it falls right into the cross section of the dimensional beam energy. After the disappearance, the discharge spark or laser light can be seen at a point in another space.

LTB-2: the dimensional beam is shielded, so it cannot be measured with infrared, and the starting laser beam cannot be detected either, because it automatically disappears and only appears at the other local point or (calculated target surface). So, there is an undetectable LTB-2 equipment output (for laser and dimensional beam), there is an undetectable field progression of the laser beam, and there is a detectable target surface where the laser impact is created.


  • infrared detection of the starting point cannot be recognized
  • no reflection effect
  • range increase

Basic test prototype LTB-2 low-energy: the dimensional transmission energy is also a low-energy system, the laser directed at the "target" is also (green laser, 5mW, 532nm, 3R)

Standard high energy laser measurements: ABSTRACT   The AFIT Center for Directed Energy’s High Energy Laser End-to-End Operational Simulation (HELEEOS) model allows for the calculation of the irradiance from within a high energy laser beam that is scattered by molecules and particulates in the atmosphere to an off-axis observation point, while incorporating the spreading effects of the turbulence and thermal blooming.  Field experiments conducted at Wright-Patterson AFB, Ohio in summer 2009 allowed for validation measurements for the HELEEOS off-axis algorithm to be collected.  Turbulence strength measurements were made at a wavelength of 1.55 µm using a state of the art bistatic turbulence profiler for both horizontal and vertical paths.  Pressure, wind speed, wind direction, relative humidity and aerosol loading data were collected simultaneously with the Cn2 measurements.  As part of the experiment, the profiler's beams were imaged off-axis with a calibrated camera array and the received irradiance of the off-axis scattering was quantified.  Characterization of the aerosol distribution along the laser path and the path to the observer is accomplished by determining the visibility and climatological aerosols for southwestern Ohio.  Comparisons between predicted and measured off-axis irradiance are made. Fiorino_Proc_SPIE_2010.pdf
