VISUAL INDICATORS FOR PRESENCE SENSING SYSTEMS

A laser scanner can include a housing, a window, and a light emitting system, which can output laser pulses of a first wavelength through the window. A light detection system can receive light of the laser pulses that is reflected by an object through the window and direct the received light to an o...

Beschreibung
Zusammenfassung:	A laser scanner can include a housing, a window, and a light emitting system, which can output laser pulses of a first wavelength through the window. A light detection system can receive light of the laser pulses that is reflected by an object through the window and direct the received light to an optical sensor that generates electrical signals from the received light. A controller can make a determination regarding a presence or position of the object based on the electrical signals. The scanner can have one or more light sources for illuminating the window with light of a second wavelength. The window can have diffusing features configured to diffuse the output light of the second wavelength. The controller can operate the one or more light sources in response to the determination regarding the presence or position of the object to provide a visual indication of the determination.
