- lighting on the shooting range
- infrared heat lamps
Question: Could these light-sources influence the measurements?
Answer: Not under reasonable circumstances
Background: For a possible influence on the measurement two properties ae important. These are
- type of light: visible light, infrared light or ultraviolet light. Expressed with the wavelength.
- intensity of the light
- sun emits mainly visible and ultraviolet light and does not influence the measurement. Furthermore, Meyton requires special roofing to be installed for outdoor shooting ranges. This roofing provides an even shadowing of the Electronic Scoring Target - and shields the Electronic Scoring Target against the sun
- lighting emits mainly visible light and does not influence the measurement
- torches (even LED) emit mainly visible light and do not influence the measurement
- Laser with visible light emit mainly visible light and do not influence the measurement
The aperture plates on the Electronic Scoring Target shield the sensors. This ensures that only infrared light from the opposite side of the Electronic Scoring Target is captured. A light-source influencing the measurement would have to be placed between sender and sensor in order to be able to shine on the sensor - this means in the centre of the Electronic Scoring Target.
Additionally, the software on the Electronic Scoring Target performs extensive plausibility checks. This ensures that an influence by strong light-sources is nearly impossible.
The intensity of the light only comes into play when the light-source shines with such intensity that the sensors are damaged physically - they are burnt.
Conclusion: an influence of a strong light-source on the measurement is excluded under reasonable circumstances - and as long as there is no light source in the centre of the Electronic Scoring Target.
