Abstract: A manually operable disinfection wand provides to a user feedback indicating effectiveness of disinfection during treatment of a target surface. The disinfection wand comprises an illuminator section having an illuminator light source, a handle section, a coupling mechanism, and a position sensor. The coupling mechanism enables a user to rotate an illuminator cover in the illuminator section relative to the handle section to selectively allow passing of light emitted by the illuminator light source for incidence on the target surface. The illuminator cover can be rotated relative to the handle section also to block the light emitted by the illuminator light source. The position sensor is placed in the disinfection wand to produce for observation by the user a signal that is indicative of speed of motion of the disinfection wand and thereby its effectiveness in disinfecting the target surface.
