Technical details and manufacturing context for Linear Sensor Array

Definition
The linear sensor array is the core imaging component of a line scan camera, consisting of multiple photodiodes or CCD/CMOS sensors arranged linearly. It captures image data one line at a time as objects move past the camera, converting light intensity into electrical signals that are processed to create continuous images of moving materials or products.
Working Principle
Light from the target object is focused onto the linear array through optics. Each photosensitive element in the array generates an electrical charge proportional to the light intensity it receives. These charges are sequentially read out and converted to digital values, creating a line of image data. Multiple lines captured over time are assembled to form a complete two-dimensional image of moving objects.
