Lindbergh Field will receive additional full-body scanners in an attempt to improve screening of passengers, the Department of Homeland Security announced.
It was unclear how many more body scanners would be installed, but they’re expected to be in service by summer.
The scanners, which will be placed in 11 airports across the country by the end of the year, are funded by the American Recovery and Reinvestment Act, according to Homeland Security Secretary Janet Napolitano.
The scanners will also be delivered to airports in Los Angeles; San Jose; Oakland; Boston; Chicago; Cincinnati; Kansas City; Fort Lauderdale, Fla.; Columbus, Ohio; and Charlotte, N.C.
The machines allow security officials to look underneath the clothing of passengers, producing a three-dimensional black-and-white image that reveals detailed outlines of every body part.
Screeners view the images from a remote, enclosed area.
Even though the faces of passengers are blurred and the images immediately deleted, some passenger rights advocates say the body scan could be too revealing and even upsetting to travelers.
