The sensor is based on an optical distance
measurement, which takes place by means of the LIDAR ("light detection and ranging") method.
The Swiss GPS maker Garmin has disclosed in an official statement that the intellectual property of PulsedLight meant for optical distance
measurement technology fits in nicely with Garmins core competencies of location and positioning.
Figure 6(a) compares the variations in the Q-factor with the optical distance for bit error rate analyzers (I) & (II).
We can achieve the maximum value of Q-factor and corresponding BER at optimal optical distance with optimal dispersion value (16.
These findings are consistent with several studies showing that accommodation is most accurate (Johnson, 1976) and oculomotor adaptation is minimal (Ebenholtz, 1992; Miller, Pigion, Wesner, & Patterson, 1983) for visual tasks located at the optical distance
of the dark focus.
The lamp also works as a no touch measurement system when used as an ODI or optical distance
The first is the optical distance
at which HUD imagery should be focused and its effects on perceptual judgments of objects in the outside scene.
