laser beam造句怎么写

By splitting a laser beam and aiming each part onto opposite sides of a polished silicon wafer, the group engineered a system of reflection and interference that traps both beams in the silicon.

The trick is to use what is known as a "fast Fourier transform" to unpick more than 300 separate colours of light in a laser beam, each encoded with its own string of information.

Even though the laser beams are not entirely painless, they have a different psychological effect on children than needles.

To reproduce the landscape in 3-D, a twin-engine plane flew over the city and fired laser beams through the dense tree canopy. The beams bounced off the ground, buildings, and other structures below.

The sharp laser beam further zeros in on a small portion of the brain.

In the process of duplicate laser boring, the crosswise pattern of laser beam determines the precision of the processing hole's shape and size.

Pointing and focusing a laser beam on a target that is rocketing skyward at thousands of miles per hour is no easy task, but the Airborne laser is uniquely able to do the job.

No, because nothing is actually crossing the surface of the moon - the dot isn't an actual object, it is just a series of photons in the laser beam hitting the surface.

The report is based on the first experiments from the National Ignition Facility (Nif) in the US that used all 192 of its laser beams.

One solution is to use a diffuse light source rather than a laser beam, says Mr O'Brien.

A team of physicists in the us has created an infrared laser beam at a point in mid air, by focusing a UV laser onto a tiny volume of oxygen molecules.

Originally, Keeling measured the speed of light in the air samples with a laser beam.

Longer laser beams mean greater sensitivity.

It transmits a laser beam through an optical cable to a robot, which angles lenses and mirrors in the end of its arm to aim the laser towards the parts that need welding.
