Hologram Industry News

UK scientists have “tied light in knots”, paving the way for new applications of laser technology. A team of physicists working at the universities of Bristol, Glasgow and Southampton accomplished the seemingly impossible feat using a series of holograms to control the flow of light.

The breakthrough could be used to offer unprecedented levels of precision in sophisticated applications that currently use lasers, such as speed cameras and measurement devices.

The pioneering British team implemented a previously abstract mathematical formula known as “knot theory”, which allowed them to manipulate light into “knots”, providing greater control over the direction and precision of the beam.

The sophisticated hologram design required for the experimental demonstration of the knotted light shows advanced optical control, which undoubtedly can be used in future laser devices.

Speaking on the exciting future of the home grown device, Professor Miles Padgett from Glasgow University, who led the experiments, said: “The sophisticated hologram design required for the experimental demonstration of the knotted light shows advanced optical control, which undoubtedly can be used in future laser devices.”

NEW DELHI: Car manufacturers say if you want to learn how to increase the life of your vehicle, visit Asli Naqli pavilion at the ongoing auto expo. There, the companies have come together to tell visitors the difference between genuine and spurious spare parts and how to identify fakes. As the name of the pavilion suggests, these manufacturers are displaying their own genuine products alongside low-quality duplicates to make visitors aware of the problems of fakes so that peolpe will be more alert the next time they take their car to a mechanic.

According to the manufacturers, busting the network of spurious auto parts makers by creating awareness is their aim. Mr. Narendra Sehrawat, a representative from Bosch Limited said, ‘‘We show people visiting Asli Naqli stall the differences in packaging colours, the product numbering and the hologram.’’

According to a study conducted in 2007 by Automotive Components Association of India, spurious parts market runs into Rs 5,300 crore in the country while the total size of the vehicle parts market is Rs 16,500 crore.

New Delhi; January 6, 2010: Liquor manufacturers and suppliers have agreed in principle to use hologram and bar coding on the bottles of Indian Made Foreign Liquor to check rampant illegal trade. After a high level meeting on Tuesday, Chief Secretary Rakesh Mehta said that the Government has fixed a deadline of April 1, for introducing of bar code on the bottles of IMFL.

Chief Minister Shiela Dikshit and Excise Minister Dr Ashok Kumar Walia have already given green signal to put hologram and bar-coding on each batch of cartons of IMFL, supplied to agencies like the Delhi State Industrial (DSIDC), wholesale cooperative stores and the Delhi Tourism and Transportation Development Corporation.
