HEADS-UP-DISPLAY
The Heads-Up-Display, or HUD, performs two critical
functions in the operation of the ProLaser III. First, it
provides the aiming reticle by which the instrument is
aimed at the desired target. Secondly, it displays the
current speed or range of the target as the operator
continues to observe the target, creating a tracking history
that is vital for admissible court evidence.
The aiming reticle is an illuminated rectangle that
approximately replicates the laser beam spot size. As
seen from the rear of the instrument, the aiming reticle is
located in the center of the HUD reflecting glass, and
defines the area where the laser pulses are transmitted.
The reticle is illuminated whenever the ProLaser III is
powered up. The intensity of the reticle is adjusted along
with the intensity of the displays, by the BRT/VOL switch
on the rear panel of the unit.
Directly below the aiming reticle is a four-character
LED numeric display. This display is used to present four
types of information to the operator:
1. Upon power-up or the activation of the test function,
the HUD display will first go through a display
segment test. The first display will briefly read
"8888"
.
2.
When the trigger is pulled and laser pulses are being
transmitted, the HUD will display four dashes
"----"
indicating that the laser is being fired and that the
instrument's range and speed measurement functions
are activated. Display of the dashes in the HUD
occurs simultaneously with the illumination of LCD
characters directly beneath the “Speed” and “Range”
text on the rear display panel. This confirms that
laser activation has taken place, and the operator's
attention is not diverted from the HUD.
