Background Suppression
Although other diffuse-mode sensors, such as fixed-focus and sharp-cutoff models, offer a degree of background suppression, true background-suppression photoelectrics are designed specifically for applications requiring the sensor to see a target very close to a reflective background. This background suppression is particularly effective when the target and background have similar reflectivity (e.g., light returned to the sensor from the target is roughly equal to the light reflecting from the background) or when dark targets are to be sensed against a lighter, more reflective background.
Background-suppression technology, in its true form, uses light triangulation to create a distinct focal plane that is the effective sensing area. Targets beyond the focal plane will not be detected.
