“Many uses exist for infrared cameras, around since the 1960s. They convert tiny differences in heat radiation into electronic signals that can then be portrayed as a still or moving image. Even so, infrared camera systems are still expensive playthings for pros, costing between $3,000 and $1.2 million.
Someday, however, they will be cheap enough for every car or home. That prospect thrills Earl Lewis, the chief executive of Flir Systems, the world's biggest stand-alone maker of infrared cameras. If you pointed a heat-sensing camera at him and asked about his mass-market opportunity, the sensor would light up like crazy.”
