DALSA Unit Builds Chips For Mars Rovers

Facebook X LinkedIn Email
WATERLOO, Ontario, June 12 -- Charge-coupled device (CCD) image sensor chips on board the two Mars Exploration Rover (MER) missions were manufactured at DALSA's semiconductor division in Bromont, Quebec. The space-qualified chips, part of sophisticated camera systems for navigation and scientific investigation, were designed in collaboration with NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. The chips are critical components in the nine electronic cameras aboard the two identical Mars rovers. Each camera integrates a scientific-grade, 1024- by 1024-pixel CCD image sensor that was...Read full article

    charge-coupled device
    A charge-coupled device (CCD) is a type of electronic image sensor used in various imaging devices, including digital cameras, camcorders, and scientific instruments. It consists of an integrated circuit containing an array of light-sensitive pixels that convert photons (light) into electrical signals. The operation of a CCD involves several key components and processes: Pixel array: The CCD contains an array of pixels arranged in rows and columns. Each pixel consists of a photosensitive...
