Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including：Control module 1, transmitting module 2, receiving module 3.Transmitting module 2 and receiving module
3 are connect with control module 1 by control line.Transmitting module 2 includes transmission eyeglass 4, laser module 6, laser driver circuit board 8
And shell.Receiving module 3 includes filter glass 5, receives light-sensitive device 7, receives signal processing circuit board 9 and shell.
In the present embodiment, receive light-sensitive device 7 be the reception photodiode of light intensity, photoelectric diode, position sensor,
One kind of cmos sensor.
Control module 1 includes control circuit board 11, indicator light 10 and shell.Control circuit board 11 is used to generate Laser Driven
Signal is controlled, and passing through control line will control signal to be sent to transmitting module 2, and laser module 6 is made to work；Acquire reception mould simultaneously
The laser signal that block 3 receives, and real-time online judgement is carried out to received signal.Laser drive control signal is with spy
Determine working frequency, certain pulses width signal.The judgment mode for receiving signal includes：The judgement of signal amplitude, frequency information
Judgement and the judgement of phase information.Laser module 5 is the laser with certain wavelength, and laser beam structure is not limited to
Dots structure, linear structure.Its type of laser can be visible ray or infrared light.
In the present embodiment, indicator light 10 indicates, while can also display working condition for the display of input/output signal
It is whether normal.Usually, indicator light 10 is LED array, charactron, liquid crystal display etc..
In detection process, transmitting module 2 and receiving module 3 are adjusted first so that the laser energy being emitted from transmitting module 2
