properties of the particular target and the environmental conditions at the time the distance of an object
is being measured.
The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the
color, the longer the range. White is highly reflective, for example, and allows longer ranges than the
color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small
target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to
a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted
energy pulses) provides good range while a steep angle on the other hand, provides limited ranging. In
addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit.
The less light (e.g. overcast skies) the farther the unit’s maximum range will be. Conversely, very sunny
days will decrease the unit’s maximum range.
