Abstract
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.
