Abstract: Method of aligning an imaging device with respect to an object, the imaging device comprising two or more optical channels, is disclosed. The method may include aiming the two or more optical channels at corresponding overlapping zones of the object such that the two or more optical channels are oriented at different angles relative to each other and off-axis relative to a central axis of the imaging device. The method may additionally include guiding or focusing the imaging device relative to the object using composite images created by combining separate images from the two or more optical channels.

Abstract: Ultraviolet (UV) light emission devices employing UV light source housing to achieve UV light emission irradiance uniformity, and related methods of use. The UV light emission devices disclosed herein are particularly suited for use in disinfecting surfaces and air. The UV light emission devices disclosed herein can be provided in the form factor of a handheld device that is easily held and manipulated by a human user. The human user can manipulate the handheld UV light emission device to decontaminate surfaces, air, and other areas by orienting the handheld UV light emission device so that the UV light emitted from its light source is directed to the area of interest to be decontaminated.
