— Good Thinking

Car mirror copies eyeglasses to eliminate blind spots

Usually when we hear the term “progressive optics” it’s in reference to bi- or trifocal glasses, that don’t have sharp lines between the different focal zones of the lenses. A group of scientists from Korea and the US, however, have recently used the technology to create something else – a prototype driver’s side car mirror that has no blind spot, yet that also doesn’t distort images in an unsafe manner.

Cold mirror makes hot astrophotos a snap

While nearly everyone enjoys a good astrophoto, the precision with which the astrograph (the telescope taking the photograph) must follow the stars is not widely appreciated. To take a good astrophoto of any but the brightest objects requires following their motion through the sky accurately. There are a number of approaches toward addressing this problem in the digital era. Perhaps the best option has now been enabled by Innovations Foresight's new ON-Axis Guider (ONAG). Read More

Building a better bicycle rear-view mirror

According to the U.S. Department of Transportation, collisions between bicycles and motor vehicles resulted in the deaths of 618 cyclists in 2010 ... and that’s just in the United States. Regardless of who was at fault in those accidents, one thing is certain – urban cyclists are safer when they’re better able to keep tabs on the vehicles around them. While helmet-mounted mirrors are a great help in that regard, many cyclists don’t use them. That’s why Canadian entrepreneurs Greg Maxwell and Richard Seck invented the Isoteko mirror. Read More

Audi's digital rear-view mirror moves from racetrack to R8 e-tron production vehicle

Audi’s digital rear-view mirror, which made its debut in the R18 e-tron Quattro and R18 ultra race cars at this year’s Le Mans 24 Hours, is set to enter small scale production at the end of this year in the Audi R8 e-tron. Unlike previous rear-view mirrors from the likes of Ford, Toyota and Mazda, which dedicate only a percentage of the mirror’s surface area to displaying vision from a rear-view camera, Audi’s digital rear-view mirror does away with the conventional mirror altogether.

Scotch tape approach could enable larger, cheaper telescope mirrors

A team led by NASA's Maxim Markevitch is investigating the possibility of building bigger X-ray telescope mirrors – up to thirty times as large as today's – using a plastic tape coated with a reflective material and then, just like a roll of Scotch tape, tightly rolled on itself. By studying cosmic rays and distant galaxy clusters, such large and significantly cheaper mirrors would allow us to learn more about the birth and evolution of the universe. Read More
