Radar and laser technologies are radically different. Radar uses radio waves while laser transmits a beam of invisible infrared light. A radar beam can be 100 feet wide at typical target range. At the same distance, the laser beam will be barely 1.5 feet in diameter. This pinpoint beam width is what makes the laser so difficult to detect. _ There are also significant differences in how the two types of speed-measuring equipment are used by police. Radar can be used from a moving patrol car.

This is not required in any jurisdiction. Also, whether the officer allows you to see the speed reading has virtually no bearing on your case. Officers can lock on radar readings and leave them on to display to any hapless victim, even though it was not their vehicle that registered the displayed speed. See similar questions...

Radar helps you see what's around you. An antenna mounted high above your boat (often on the mast of a sailing vessel) sends radar waves down towards the ground, hoping to pick up reflections of land or other boats below. It's not foolproof - it can often pick up images of waves instead of real objects - but it definitely helps you see what's around you, especially in conditions of poor visibility.

Hot (conventional or thermal) and cold (photodynamic) lasers differ in wavelength. This means that the light used for the surgical treatment is different, although they have a similar effect. Photodynamic therapy requires injection of a drug that makes the bleeding vessels more sensitive to the laser, allowing the laser to distinguish it from surrounding tissue. The cold laser does not damage the healthy tissues of the eye. See similar questions...

Most of the patients as well as doctors confuse laser therapy with laser surgery. Both of them are branches of laser medicine. However, laser therapy is entirely different than laser surgery. It encompasses scientific use of healing properties of different laser beams in various diseases to enhance health and beauty. See similar questions...

Long range radar detection. Simply put, a detector really has only one single mission: to provide enough advanced warning of radar and laser signals to allow you to check your speed and react appropriately. Long range detection relates directly to sensitivity: the greater the detection range, the more protection a detector delivers. Detecting X and K band radar at long range is easy compared to Ka band radar, and most detectors today do it reasonably well. But here's the problem. See similar questions...

This can be confusing, because sutures (stitches) are used in both techniques. In the suture technique there is no cutting and no tissue removed. The sutures are passed in and out of the eyelid and are buried, and remain there permanently. There are no stitches outside on the skin. This is best in younger patients with thin eyelids with little fat. The laser technique is like other Asian blepharoplasty cutting techniques, but the laser is used to cut. See similar questions...

Laser light beams vaporize top layers of the skin to lessen the appearance of wrinkles, scars, birthmarks or to generally resurface facial skin. Laser resurfacing can be used alone or in combination with other skin resurfacing techniques. Learn more about Laser Resurfacing. Dermabrasion is a facial sanding technique used by your plastic surgeon to treat deep scars and wrinkles, raised scar tissue, and some severe cases of cystic acne. See similar questions...

Electrolysis and Laser are two different processes. Laser treats whole areas of hair growth using light while Electrolysis achieves results by treating each hair individually. Laser treatment cannot be used for some areas and does not work well for certain types of skin and hair. Electrolysis can be used anywhere on all types of hair and is an efficient way to clear blonde or colourless hair that cannot be touched by laser. Electrolysis is generally not considered to be a painful procedure. See similar questions...

A There is one active radar jammer that returns a variable doppler shift that does have success in jamming K band radar guns. The Phantom RCD. There are several laser jammers like the Blinder M-10 that are also very effective in Jamming All current laser guns used by the Police. See similar questions...

No. The police officer is not required to present the radar/laser gun at the time you are being cited. The driver is only entitled to know the nature of the charge. The officer must only provide sufficient evidence to the trial judge, and is not obligated to prove guilt to the driver. It is up to the driver to dispute the traffic ticket to avoid points and increases in automobile insurance premiums. See similar questions...

Good question. Radar detectors are some defense against police radar because they can pick up a radar signal well in advance of your being within the radars range of operation. In other words, your radar detector notifies you that a police radar is there before they know that you are there. This is NOT so with laser. Laser guns must target a reflected area, such as the License plate or headlight, with a very small laser beam, one not more than 18 inches wide. See similar questions...

The term laser stands for Lightwave Amplification by Stimulated Emission of Radiation. A laser beam is a concentrated light source with specific characteristics. The characteristics of laser light include the following: Monochromatic: In laser light, all electromagnetic waves have the same wavelength and, therefore the same color. Intense: Because its radiation is coherently concentrated on one spot, laser light is very powerful. See similar questions...

A Laser System is the optical head and power supply used together to generate laser light. A Laser Product is a device that integrates a laser system for another purpose. See similar questions...

A Officers, by law, must establish a "visual tracking history" of your car. This means they must be able to identify the make and model of the vehicle before assessing speed with a radar or laser gun. This is usually 600 metres or less. In most instances, officers rarely use a radar or laser gun past 1 kilometre. The maximum range of the Prolaser 2 is 610metres. A The US courts have consistently ruled, i.e. Connecticut v. Tomanelli (1966), Wisconsin v. See similar questions...

A For radar, the claims are valid. The letters in RADAR stand for RAdio Detection And Ranging meaning a radar transmission is very similar to your favorite radio station. Radio waves bounce off metal signs, the truck in front of you, buildings, and other reflective objects. See similar questions...
