Most RS does not even mention photography or sensors. Where photography is mentioned in conjunction with RS, sensors are much less likely (5.5:1) not to be mentioned. Where there is photography, sensors are not discussed.

Most RS does not mention detectors, sensors, scanners. Sensors is the preferred term, talking in the plural. Then detectors alone. Then detectors or sensors.

They are similar, but the differences are probably significant. The total is slightly different. Could be rounding.
