A touchscreen system for locating an opaque object in a target region, detects interruption of light beams. Each of the touchscreens have one or more optical emitters to create the beams, and one or more optical detectors to provide detection signals arranged to use emission wavelengths which are compatible with night vision apparatus, and having an NVIS radiance smaller than 1.7×10−11 NR.
1. A touchscreen for use with cameras, sights or night vision goggles, said Touchscreen being for locating an opaque object in a target region, by detecting interruption of light beams, the touchscreen comprising: one or more optical emitters arranged to create said light beams, and one or more optical detectors arranged to provide detection signals, said optical emitters emitting wavelengths which do not interfere with said cameras, sights or goggles, whereby a substantial peak of the spectrum of the said optical emitters is not below 900 nm. 2. The tou...
