While there are already various anti-blind-spot automobile mirrors on the market, these all tend to incorporate a very curved surface that drastically distorts the appearance of objects seen in them – given that drivers use their mirrors to avoid getting in accidents, it’s kind of important that those mirrors show the surrounding traffic as it really is. That’s why Dr. Andrew Hicks, a mathematics professor at Philadelphia’s Drexel University, has created a side mirror that eliminates the blind spot, while causing almost no distortion.
Although Hicks’ mirror is made up of one continuous piece of glass, it has a subtle non-uniform curve that is the result of tens of thousands of calculations. “Imagine that the mirror’s surface is made of many smaller mirrors turned to different angles, like a disco ball,” he said. “The algorithm is a set of calculations to manipulate the direction of each face of the metaphorical disco ball so that each ray of light bouncing off the mirror shows the driver a wide, but not-too-distorted, picture of the scene behind him.”
As a result, the mirror offers drivers a field of view of approximately 45 degrees, while any distortion of shapes or flat lines is “barely detectable.” A regular flat driver’s side mirror, by contrast, can only manage about 15 to 17 degrees.
