Embodiment Construction
[0028] As shown in Figure 1, the target finding device of the pulsed laser range finder of the present invention, referring to Figure 1, is made up of three parts: a laser emitting and receiving circuit, a laser signal processor and a microprocessor. The laser signal processor includes beat generator, PLL phase-locked loop frequency multiplier, adder, differential circuit zero elimination circuit, address generator, dual-port synchronous random access memory (RAM) and multi-way switch and other electronic circuits. The beat generator is composed of D flip-flops; the differential circuit is composed of two D flip-flops and an inverter;
[0029] The connection relationship is as follows:
[0030] The (110) emission request signal of the microprocessor part is connected to the emission request end of the zero elimination circuit (101) of the laser signal processor (100); the address line of (110) is connected to the external address end of (107); (110 ) data line is connected to...
