Boeing will soon mount laser beam control system on Army truck in next phase of project
The eight-wheel, 500-horsepower Oshkosh Defense HEMTT A4 - a widely used military vehicle - will be shipped to Boeing's Huntsville facility this spring for integration with the laser's rugged beam control system, or BCS.

Need help calculating the diameter of a laser beam projected onto the moon?

The collimation of a laser beam is limited by diffraction; that is, the angular beam spread Δθ is at least as large as Δθ λ/D, where D is the diameter of the laser's aperture. What is the diameter of the beam spot projected on the Moon, 3.8*10^8 m from a laser of aperture diameter 16 mm emitting light of wavelength 510 nm?

The spread of the beam at distance L will be L*tanθ. Because the angle is small, tanθ ~ θ so the spread is L*λ/D = 12 km

I'm sure that most of us at some point or another have fallen victim to a speed trap. At the very least, more of us know what it's like to simply get a speeding ticket. The radar guns that police and troopers are using now a days is very advanced and very accurate with laser technology. And keeping pace with the advances in radar guns are the laser radar detectors.

You should be made aware that police officers do not look to kindly on the sight of a radar detector in a vehicle. While they can be very helpful to assisting you in not getting pulled over for speeding, you should avoid getting pulled over for anything else with one installed.

Laser radar detectors work by picking up the projected signals that the radar guns emit. Laser radar guns emit a beam of light directly onto the vehicle that it is trying to acquire information about. Usually, without a scrambler/detector, if you are hit with this light beam while speeding you have a one-way trip coming to ticket town.

When the vehicle is hit with the light, it relays the information back to the police officer in the form of the difference mathematically. For instance, if a police officer is traveling at 60 MPH and his bounce back indicated 20 MPH, your vehicle is traveling at 80 MPH, and you are most certainly in line for a hefty fine.

There are different types of radar guns, and the advancements of the detectors have been able to handle them all. With the laser detectors, the beam shot at the car to register your given speed is reflected back with a new informational beam from the detector. This will not register any actual figures, but rather scramble the results so that they are inconclusive. The detectors main job is to warn you of the potential to be gunned at any given time.

There are many great names in laser radar detectors, but you really do get what you pay for in terms of detection technology. It's better to go with the some of the top names, and these include: Cobra, Beltronics, and Escort. They might be more than you thought you'd pay, but when you think of the tickets you won't be getting, it's kind of worth the investment.

Laser radar detectors are a must for anyone who has a little bit of a lead foot. Most of the police forces are going with laser radar guns because they are more accurate and easier to use all around. Make sure you get a detector that can handle this and the others. Happy driving.

Safe driving with quality wireless radar detectors or getting warning of radar traps ahead with voice alert radar detector would be possible only when you get a quality device. Getting best products at best prices becomes possible by logging on to the website at http://www.radardetectorsnow.com.
