Abstract

The invention provides a handheld laser range finder. The handheld laser range finder comprises a shell, a control circuit board, a first laser indicator light, a second laser indicator light and/or a third laser indictor light, and a fourth laser indicator light, wherein the control circuit board is arranged in the shell, the first laser indicator light, the second laser indicator light and/or the third laser indictor light and the fourth laser indicator light are arranged on the shell, a calculation processing module, a laser transmitting module, a laser receiving module and a display module are arranged on the control circuit board, the first laser indicator light, the second laser indicator light, the third laser indictor light and the fourth laser indicator light are controlled by the laser transmitting module to transmit measurement light signals to an object to be measured, the reflection light signal of the object to be measured is received through the laser receiving module, and the width distance or the height distance of the object to be measured is obtained through calculation conducted by the calculation processing module according to the measurement light signals and the reflection light signal and is displayed through the display module. According to the handheld laser range finder, distance measurement can be conducted anytime and anywhere extremely conveniently, and the accuracy and the effectiveness of laser ranging are improved.

Description

technical field [0001] The invention relates to the technical field of laser ranging, in particular to a hand-held laser ranging instrument. Background technique [0002] With the increasing rise of the construction industry, all kinds of measuring instruments have become dazzling, and the measurement methods are becoming simpler and faster, especially the supervision units and construction units need to check and accept the space height and width of various buildings. A convenient and quick measuring tool is essential . [0003] Laser range finder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. The laser range finder is light in weight,...
