BACKGROUND Laser range finders are commonly implemented based on a measurement
of the round trip delay of a signal echoed by a target. For example, the round trip delay is …

BACKGROUND Laser range finders project a laser beam to measure the distance to a target
object. Traditional laser range finders are relatively compact, while still providing relatively …

(*) Notice: Subject to any disclaimer, the term of this a target is determined by adjusting the
measured parameter by a measurement error. The error adjustment is based on the …

A range finder system for determining a range of an object. The system includes a source of
laser radiation configured for transmitting a plurality of pulses, a first detector, a second …

A method and an apparatus for measuring the distance to a target according to the time-of-
flight of laser pulses. The apparatus includes a transmitter of laser impulses toward the …

The range of a threshold detection laser range finder is increased by adding a low cost
Analog-to-Digital converter and Sampling a portion of a reflected laser pulse. The Slope of …

Simple range sensing systems which can quickly deter mine the range to one target or point
are well known. These systems can be used in many applications, from determining a …

An active receiver having a digital-pixel focal plane array (DFPA) ranges a target when
observing return pulses from a pulsed laser beam synced with the receiver. The DFPA …

2. Background The lasing medium of a variety of lasers produce an output characterized by
a plurality of fixed frequency laser lines (also referred to herein as spectral lines). Such …

Laser rangefinders are well known, and are used to measure distances to targets. Generally,
a laser transmitter is used to beam a high intensity pulse of light onto a Selected target. The …
