Many emission unit laser rangefinder with strengthen remote range finding ability

The utility model discloses a many emission unit laser rangefinder with strengthen remote range finding ability relates to the laser action field. The device includes: laser receiving unit, multichannel laser emission unit and synchronization pulse produce the unit. Synchronization pulse produces the originated moment fine synchronization's of unit output multichannel pulse laser control impuls, input multichannel laser emission unit respectively in control multichannel laser diode synchronous luminous. Because there is certain angle of divergence in the collimation facula, the outgoing facula of multichannel collimation unit is superposeing at a distance each other, and at the angle of vision within range of laser receiving unit, the laser receiving unit was received the laser intensity and is strengthened by a wide margin, had strengthened the range finding ability of laser instrument. The device is arranged in scanning formula laser rangefinder system, and the facula separation of multichannel collimation unit superposes at a distance each other nearby, on the basis of not improving laser emission power, can strengthen the remote range finding ability of laser instrument, can realize laser instrument people eye one -level safety again.
