A push broom scanner, also known as an along-track scanner, is a device for obtaining images with spectroscopic sensors. The scanners are regularly used for passive remote sensing from space, and in spectral analysis on production lines, for example with near-infrared spectroscopy used to identify contaminated food and feed. [ 1 ]
There are push broom scanners and the related whisk broom scanners (spatial scanning), which read images over time, band sequential scanners (spectral scanning), which acquire images of an area at different wavelengths, and snapshot hyperspectral imagers, which uses a staring array to generate an image in an instant.
A broom is made up of two parts: the handle, which is a long cylindrical stick, and the stiff fibers lined parallel at its base. [1] The United States International Cooperation Administration made a distinction between brooms based on bristle quality. Parlor brooms are made of smooth green fibers and typically have brushes 14 to 18 inches long.

The term "forward-looking" is used to distinguish fixed forward-looking thermal imaging systems from sideways-tracking infrared systems, also known as "push broom" imagers, and other thermal imaging systems such as gimbal-mounted imaging systems, handheld imaging systems, and the like. Pushbroom systems typically have been used on aircraft and ...
The camera is a "push-broom" type imager, generating an image as the spacecraft turns moving the sensor in sweeping motion over the observation area. [ 10 ] One of the constraints for JunoCam hardware was mass, which limited the size of the optics.
