A laser can detect the distance of an object as well as an object's reflectance, or intensity. To detect the distance of the laser source to a particular object, the round trip travel times of a laser pulse are accurately measured and recorded from the source, to the target and back. Since the speed of the laser pulse is known, using the formula distance = velocity * time, the distance can be calculated. Laser sensors can also record the amount of light returned from a target surface, which is characterized by its reflection coefficient and its surface properties. For example snow would be the highest reflectance and asphalt would be one of the lowest.
What else can I help you with?
How do you detect a laser beam?
You can see light rays with dust, flour, etc. If you turn on a flashlight, you can drop dust right where the light travels to actually see that beam of light. The same thing happens with red laser beams.
What is the working principle of a laser?
A laser works by emitting a concentrated beam of light through a process called stimulated emission, where photons are amplified and aligned to create a powerful and focused beam of light.
What does abbreviation LASER stand for?
Light Amplification by Stimulated Emission of Radiation (LASER or laser.)
How does laser cooling work to lower the temperature of atoms or molecules?
Laser cooling works by using laser light to slow down and cool atoms or molecules. The laser light is tuned to a specific frequency that matches the energy levels of the atoms or molecules, causing them to absorb and emit photons. This process removes kinetic energy from the atoms or molecules, lowering their temperature.
What do you call a strongly concentrated light?
A strongly concentrated light is called a laser.
How does the laser works?
The laser works by reflecting and amplifying a beam of light through a tube of mirrors.
Why do we use radio waves in radar why not other waves?
"Radar" comes from RAdio Detection And Ranging. If it didn't use radio it would be called something else.LIDAR (LIght Detection And Ranging) is laser instead of radio. That uses light.
What is a laser detection used for?
A Laser Detection is used to monitor one's speed. It helps eliminate traffic offenses for individuals as they would insert this device in their vehicle.
How do you detect a laser beam?

What makes up laser light and how is it used?
Laser light is different from ordinary light. Laser light consists of light waves that all have the same wavelength, or color. The waves are coherent, or in step. A laser is a device that produces a narrow beam of coherent light. The word laser comes from a phrase that describes how it works: light amplification by stimulated emission of radiation. Light amplification means that the light is strengthened. Stimulated emission means that the atoms emit light when exposed to electromagnetic radiation.
What sort of threat detection system does the Coyote have?
Laser range warning receiver. The laser range warning receiver provides the Coyote with 360 degrees of detection on enemies and their targeting systems
What is the working principle of a laser?
A laser works by emitting a concentrated beam of light through a process called stimulated emission, where photons are amplified and aligned to create a powerful and focused beam of light.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
How is a laser printer used?
It works throug laser
Is a laser artificial sunlight?
No. Laser light is artificial light, but it is not sunlight.
What dose laser stand for?
Light amplification by stimulated emission of radiation(LASER or laser)
How do you perform frequency signal processing on 3d laser scanner images so that the colours match those of an ordinary camera photograph?
That would be hard, if not impossible. Lasers work purely by reflection back from an object. Colour information comes from the frequency of light. Your detection equipment would have to simultaneously detect the laser light and the different frequencies of light.
