EOTECH was the first company to create holographic sights, [1] having solved the problem of wavelength instability exhibited by laser diodes. They introduced their first-generation holographic weapon sight at the 1996 SHOT Show , which won the Optic of the Year Award from the Shooting Industry Academy of Excellence.
A holographic weapon sight or holographic diffraction sight is a non-magnifying gunsight that allows the user to look through a glass optical window and see a holographic reticle image superimposed at a distance on the field of view. [1] The hologram of the reticle is built into the window and is illuminated by a laser diode.
These are the highest peak-power pulsed laser diode arrays in the world. [17] L4 ATON – 10PW laser, 2 kilojoule – status: in operation - This laser system is designed to generate an extremely high peak power of 10 PW (Petawatt) in pulses with duration of 150 fs, pulse energy 1.5 kJ and repetition rate 1 shot per minute.

Sights can be a simple set or system of physical markers that serve as visual references for directly aligning the user's line of sight with the target (such as iron sights on firearms), [3] or optical instruments that provide an optically enhanced—often magnified—target image aligned in the same focus with an aiming point (e.g. telescopic ...
This is the scenario Americans could face in Trump’s second term. Under Trump, Christian nationalists will have unprecedented access to the power of the federal government. Trump’s GOP has ...
A 7-year-old rivalry between tech leaders Elon Musk and Sam Altman over who should run OpenAI and prevent an artificial intelligence "dictatorship" is now heading to a federal judge as Musk seeks ...
A photophone receiver and headset, one half of Bell and Tainter's optical telecommunication system of 1880. Optical communications, in various forms, have been used for thousands of years. The ancient Greeks used a coded alphabetic system of signalling with torches developed by Cleoxenus, Democleitus and Polybius. [1]
