What is a Linescan Camera?

A Linescan Camera is a type of digital camera in which an image is built by combining a sequence of readings from a single row of photo-optical sensors. As the scene to be imaged moves at right angles to the row of sensors, a ‘picture’ is built up “line by line”. Such an arrangement can be a cost-effective means for capturing an image that is moving rapidly with respect to the camera, or one where one or both dimensions of the image is quite large compared to the camera.
