Is NASA wasting US taxpayers' hard-earned money?
Next time you share an amazing photograph with a friend, do remember that NASA made its technology possible. The image sensors that are used today in modern digital cameras, smartphones, and GoPros were first developed in the early 1990s at NASA's Jet Propulsion Laboratory by scientist Eric Fossum.
In the 1980s, spacecraft imaging was done using charge-coupled device (CCD) technology, which was integral to founding the digital camera industry.
CCD acts as a “bucket brigade,” passing along a light-generated charge from pixel to pixel in a microchip’s array. When the charge reaches the end of the array, it gets amplified and recorded.
A JPL engineer Eric Fossum thought there was a better way. CMOS technology, which had changed microprocessors, allowed each pixel to also serve as a charge amplifier, using less energy and making each pixel more sensitive.
Major companies like Kodak and AT&T Bell Labs eventually licensed the technology. Fossum, along with several JPL colleagues, founded a company called Photobit to develop it further. By the end of the decade, CMOS sensors had become the standard in the digital camera industry.
GoPro later leveraged CMOS's unique, low-power capabilities to make cameras even smaller. That allowed the video to be shot from the front of surfboards, the tops of helmets, and just about any place else you can imagine.
