New imaging system with ‘loose fibres’ developed

Washington: A team of researchers from MIT which included an India-origin scientist developed a new imaging system that consists bundle of optical fibres and it does not have a need for lenses or a protective housing.

For medical applications, where the diameter of the bundle — and thus the number of fibers — needs to be low, the quality of the image could be improved through the use of interferometric methods.

The fibres are connected to an array of photosensors at one end and the other ends can be left to wave free so they could pass individually through micrometer-scale gaps in a porous membrane, to image whatever is on the other side.

Bundles of the fibres can be fed through pipes and immersed in fluids – to image oil fields, aquifers or plumbing without risking damage to watertight housings.

And tight bundles of the fibres could yield endoscopes with narrower diametres since they would require no additional electronics.

“Previous works have used time of flight to extract depth information. But in this work, I was proposing to use time of flight to enable a new interface for imaging,” explained Barmak Heshmat, a postdoc at MIT Media Lab.

Heshmat is the first author on the paper, joined by associate professor of media arts and sciences Ramesh Raskar and Ik Hyun Lee, a fellow postdoc.

The researchers reported the results in the journal Nature Scientific Reports.(IANS)

  • JY Pillay has been appointed as the acting President of Singapore
  • Pillay, also the Chairman of the Council of Presidential Advisers, is a veteran civil servant of Indian Origin
  • The Singapore polls take place on 23rd September

September 2, 2017: Indian-origin veteran civil servant JY Pillay on Friday took over as Singapore’s acting President until a new head of the state is elected later this month.

The temporary appointment of Pillay, Chairman of the Council of Presidential Advisers (CPA), follows the completion of President Tony Tan Keng Yam’s six-year term on Thursday, the Strait Times reported.

The nomination day for the Presidential election is September 13, followed by polling day on September 23.

According to the report, when the office of President is vacant, the first in line to exercise its powers is the CPA Chairman, followed by the Speaker of Parliament. This is the first time the office has fallen vacant since the elected presidency was introduced in 1991.

Pillay is no stranger to exercising the powers of the President. As CPA Chairman since 2005, he has been acting President each time the President goes on an overseas trip. He acted as President in May, when Tan made state visits to Europe.

He has served more than 60 such “stints”– the longest of which was 16 days in April and May of 2007 when then President SR Nathan visited Africa. (IANS)

  • He refused to defend US President Donald Trump’s economic agenda following the racial violence in Virginia
  • He said he will speak out against such abuse as long as he has a platform to do so

Washington, August 24, 2017: An Indian origin CEO says he was racially abused and was told to “go back” to India and also take along top Indian-American diplomat Nikki Haley after he refused to defend US President Donald Trump’s economic agenda following the racial violence in Virginia.

Ravin Gandhi, founder, and CEO of GMM Nonstick Coatings, a global supplier of coatings for cookware and bakeware, penned an op-ed for CNBC following the Charlottesville racial violence but in response was slammed and racially abused by readers, the Chicago Tribune reported.

 At least one woman was killed and dozens were injured in Charlottesville last week during clashes between white supremacists and counter-protestors at a rally. Trump, instead of blaming white supremacists, held both sides responsible for the violence and was criticised by both Democrats and Republicans for the response.

“I recently told the New York Times I was ‘rooting’ for certain aspects of Trump’s economic agenda,” Gandhi, 44, wrote in the article.

“After Charlottesville and its aftermath, I will not defend Trump even if the Dow hits 50,000, unemployment goes to 1 per cent, and GDP grows by 7 per cent… I will not in good conscience support a President who seems to hate Americans who don’t look like him.

“The fact that Trump equated hate groups with those protesting hate lit me up,” Gandhi said. “His moral leadership on this issue is reprehensible.”

US-born Gandhi, after his op-ed was published, received a voicemail from an alleged Trump supporter, who told him to “get your (expletive) garbage and go back to India”.

“You can take that other half-(expletive) Bangladesh creep with you, Nikki Haley,” the woman said in the message.

“She’s the one that started all this when she took down the Confederate flag. So don’t tell us that you gave him a chance. We don’t give an (expletive) who you gave a chance, OK? We’re going to start taking down Buddhist statues and see how you and Nikki Haley like that.”

The caller told Gandhi to “go clean up your own (expletive) country, it’s a filthy mess”.

He soon posted the voicemail on the social media and also shared the nastier emails he received, the report said.

“It was obvious that people thought my professional position somewhat protected me,” he said. “I wanted to show people that racism is blind to socioeconomics.

“Even though my race is a complete non-issue in my day-to-day life, the sad reality is there’s a group of racists in the USA that views me as a second-class citizen,” he said.

“I wanted my peers in the business community, the civic community, my friend community to see that this can happen to me. Because there’s this delusion that racism is dead because (Barack) Obama was elected (President),” Gandhi said.

He said while his sharing a “bigoted” voicemail may not make a big difference, he will speak out against such abuse as long as he has a platform to do so. (IANS)
