Chinese researchers have developed a technology that they claim could see an object hidden over a kilometre far.&nbsp;

The scientists say that non-line-of-sight (NLOS) imaging could be used for everything from policing to defence, reports SCMP.&nbsp;

According to the research paper published earlier this month in the Proceedings of the National Academy of Sciences, the researchers at the University of Science and Technology set up a laster emitter 
at their campus in Urban Shanghai and hid a mannequin behind a flat-screen inside a flat 1.43 km away.&nbsp;

A pulse laser was thrown onto a wall inside the flat, which scattered the light in different directions.&nbsp;

Some of the photons were reflected on to the mannequin, while others travelled to a sensor placed next to the laser emitter.

The photons that struck the hidden object were then reflected back onto the wall and bounced back a third time to hit the sensor.

The researchers then calculated how far each part of the mannequin was placed and recreate a three-dimensional image through an algorithm.&nbsp;

"This range is about three orders of magnitude longer than previous experiments," the scientists said in the article.&nbsp;

"The results will open avenues for the development of NLOS imaging techniques and relevant applications to real-world conditions."

A US Navy warship has successfully tested a new high-energy laser weapon that can destroy aircraft mid-flight.

The Navy, in a statement on Friday, said lasers, which it calls directed energy weapons (DEW), can be effective defences against drones or armed small boats.

Images and videos provided by the Navy's Pacific Fleet, show the amphibious transport dock ship USS Portland executing "the first system-level implementation of a high-energy class solid-state laser" to disable an aerial drone aircraft.

The power of the weapon is expected to be a 150-kilowatt laser. The images show the laser emanating from the deck of the warship.

The Navy, in the statement, did not give a specific location of the laser weapons system demonstrator (LWSD) test, saying only that it occurred in the Pacific on May 16.

The US Navy has been developing directed-energy weapons (DEWs), to include lasers, since the 1960s.

DEWs are defined as electromagnetic systems capable of converting chemical or electrical energy to radiated energy and focusing it on a target, resulting in physical damage that degrades, neutralises, defeats, or destroys an adversarial capability.

"The Navy's development of DEWs like the LWSD provide immediate warfighter benefits and provide the commander increased decision space and response options," the statement said.

To curb the menace of rash driving on roads, Gujarat police has equipped its traffic unit with high-tech laser guns for detection of overspeeding by vehicles in the city.&nbsp;

The riders will be fined Rs 400 for exceeding the speed limit of 40 km/hr. The gun uses laser technology to detect the speed of a vehicle plying on road.

It has the capability to record the speed of three vehicles simultaneously in a second, even if the vehicles are a kilometre away.

Speaking to ANI, ACP (Traffic) Amita Vanani said, "We have formed a team who will be monitoring over speeding by using laser-equipped speed guns.

These high technology speed guns will capture the vehicle number, speed and the picture of the drivers.

The challan is issued with complete evidence."She added that this step was taken to curb traffic violations that were peaking in the past few days.&nbsp;

With an aim to ensure safety in railways, the Central Railway has come out with an innovative idea of installing visual indicators in local trains to Mumbaikars.

Central Railway has installed a blue light visual indicator just above the entrance of one EMU coach for guiding the commuters not to board the running train, at the last moment.

The indicator flashes when to stop boarding the train before it becomes unsafe and draws a boundary on the platform which is the minimum clearance level for commuters to avoid accidents while the train is in motion.

The device will definitely act as a psychological barrier from boarding the moving train and also as a deterrent to the people.

The work of installing the blue light visual indicator was carried out in Kurla car-shed of Central Railway under the guidance of DK Sharma, General Manager, Central Railway.

Central Railway would monitor the performance of the new blue light visual indicator and based on the outcome and commuter feedback, a decision would be taken on the installation of visual indicators on more coaches and rakes of Mumbai suburban locals.&nbsp;
