Linear array sensors consist of a linear array of integrating photosensing pixels which measure incident light over a user-defined exposure time and generate a voltage or digital output which represents the light exposure at each pixel. The sensors are available in a variety of lengths and pixel resolutions. The analog output may be directly interfaced to an ADC for digital processing or for comparing black/white thresholds. Applications include contact image sensing, optical character recognition, edge detection, and object measurement in products such as copiers, document scanners and spectroscopy.
