A laser range signal-processing device comprises a timing interval generator, a microprocessor unit, a programmable delay unit, a laser transmitter, a laser receiver, a high gain amplifier circuit and a memory. A signal-processing method of the laser range finder includes a first step in which the measurement block number and the laser emission time are set up. Thereafter, the sampling of the laser reflection signal of each block is done in sequence so as to determine a block in which an object is located. A laser beam of a predetermined delay time is emitted to the block in which the object is located. The reflective laser signals are sampled and processed to attain a precise distance between the laser range finder and the object.

1. A signal processing method of a laser range signal, said signal processing method comprising the steps of:(A) dividing a total sampling time Tt of the laser range finder into a plurality of blocks and setting a total numbers of times by which a laser beam is emitted at each of the blocks; (B) determining a block in which an object is located by sampling sequentially laser signals reflected from the blocks; and (C) emitting at a predetermined delay time a laser beam at a block in which the object is located, thereby resulting in laser reflection signals which are sampled and computed to attain a range value between the laser range finder and the object.
