- Als Zeilenkamera bezeichnet man einen Kameratyp, der nur eine lichtempfindliche Zeile (Zeilensensor) aufweist – im Gegensatz zum zweidimensionalen Sensor, der über eine Vielzahl von Zeilen verfügt. Obwohl Zeilensensoren in etwa die gleichen Pixelgrößen aufweisen wie Flächensensoren, kann die Zeilenlänge viel größer sein. Anstelle der maximalen 1.000–4.000 Pixel Breite bei Flächensensoren kann eine Zeilenkamera 17.000 Pixel oder mehr aufweisen. Folglich liefert eine Zeilenkamera bei vorgegebenem Objektfeld eine bessere räumliche Auflösung. Darüber hinaus lässt sich eine Zeile wesentlich schneller als eine Fläche auslesen. Allerdings muss durch die meist wesentlich höheren Taktraten gegenüber einer Flächenkamera auch deutlich mehr Licht vorhanden sein. (de)
- 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. The moving scanner line in a traditional photocopier (or a scanner or facsimile machine) is also a familiar, everyday example of a push broom scanner. Push broom scanners and the whisk broom scanners variant (also known as across-track scanners) are often contrasted with staring arrays (such as in a digital camera), which image objects without scanning, and are more familiar to most people. In orbital push broom sensors, a line of sensors arranged perpendicular to the flight direction of the spacecraft is used. Different areas of the surface are imaged as the spacecraft flies forward. A push broom scanner can gather more light than a whisk broom scanner because it looks at a particular area for a longer time, like a long exposure on a camera. One drawback of push broom sensors is the varying sensitivity of the individual detectors. Another drawback is that the resolution is lower than a whisk broom scanner because the entire image is captured at once. Examples of spacecraft cameras using push broom imagers include Mars Express's High Resolution Stereo Camera, Lunar Reconnaissance Orbiter Camera NAC, Mars Global Surveyor's Mars Orbiter Camera WAC, and the Multi-angle Imaging SpectroRadiometer on board the Terra satellite.

- 푸시 브룸 스캐너(Push broom scanner, 추적 스캐너를 따라서)는 광학 카메라로 위성 영상을 얻기 위한 기술이다. 그것은 공간에서 수동 원격 탐사를 위해 사용된다. 푸시브룸 감지기에는 우주선 비행 방향에 수직으로 정렬된 감지기 선이 사용된다. 우주선이 전방으로 비행하면서 지표의 다른 지역이 영상화된다. 푸시브룸스캐너는 카메라에 대한 장기 노출처럼, 특정 지역을 장시간 동안 관찰하기 때문에 위스크 브룸 스캐너 보다 더 많은 빛을 모을 수 있다. 푸시브룸 감지기의 한가지 단점은 개별 탐지기의 다양한 민감도이다. 관측 또는 광범위 도구로 알려진 이러한 감지기는 일반적인 카메라의 광각 렌즈와 비슷하다.
