Accompanying drawing explanation
Fig. 1 is the system connection layout of a kind of range finder using laser inspect on colligated-function of the present invention equipment.
Embodiment
A kind of range finder using laser inspect on colligated-function equipment, by microprocessor, man-machine dialog interface, burst pulse power drive level luminous intensity control circuit, laser pulse signal synchronizer, pulsed laser energy detector and prime amplifier, printer, Display panel and key control circuit, precision time delay signal generator, repetition frequency precision timing device; High-speed data acquisition converter and printer interface control circuit composition; Wherein, man-machine dialog interface connects microprocessor by Display panel and key control circuit, burst pulse power drive level luminous intensity control circuit connects microprocessor by precision time delay signal generator microprocessor, laser pulse signal synchronizer by repetition frequency precision timing device, pulsed laser energy detector and prime amplifier connect microprocessor by high-speed data acquisition converter, and printer connects microprocessor by printer interface control circuit.Described precision time delay signal generator and laser pulse signal synchronizer are interconnected.
Basic thought of the present invention is based on the principle of work of simulated laser range finder and Laser Transmission process, range finder using laser operationally, first a laser pulse is launched from its transmission channel, be radiated on testee through propagation in atmosphere, then diffuse reflection, the receiving cable of range finder using laser receives irreflexive return laser beam, range finder using laser inside is provided with the transmitting of laser pulse, reception and timing module, its distance of passing by can be calculated according to laser pulse from being transmitted into the time returned, thus obtain the distance between measured target and range finder using laser.And the reception of the inspect on colligated-function equipment of this programme and range finder using laser, transmission channel are corresponding, transmitting, receiving cable are provided respectively, checkout equipment inside is relative set timing module also, realize the double dummy of the target echo time on corresponding certain distance, energy, target simulation echo-pulse can be replaced by checkout equipment, realize the robotization of range finder using laser range performance, digital measuring.
Wherein, the present invention uses double frequency double light path coupled method to be first laser ranging, and irreflexive for target distant target echo is simulated by semiconductor laser by this method, when after the spectrum and spatial character of this echo of simulation, gets final product the logical block work of drive laser.Flight time in laser pulse respective distance is then realized by precision time delay module.Like this laser pulse is converted to time response in the lag characteristic in space, thus distant target to be furthered to tested instrument front end from certain distance, instead of the traditional detection method that range finder using laser Performance Detection must have the actual cooperative target in a distant place.
This programme is to the detection of measurement range of laser range finder, first it is laser pulse working time corresponding to measured laser range finder ranging by arranging delay time, namely control to start timing after checkout equipment receives " sampling " pulse, after timing terminates, Microprocessor S3C44B0X sends an analogue echo pulse signal respectively, simultaneously, Microprocessor S3C44B0X pulsed laser energy detector and prime amplifier send the energy of laser pulse, make this energy equivalence in the energy of respective distances target echo, so just can target echo pulse in corresponding ranging on the receiving cable of range finder using laser, according to display result, can judge that range finder using laser could meet range index requirement under normal circumstances at optical axis.
