One；
One is used for the light beam launched of reflex reflector one and the speculum two being be arranged in parallel with speculum one；
And the telescope be arrangeding in parallel with the laser.
Preferably, the laser keeps certain distance to set with telescope, and both diameter parallels and structure do not connect mutually
Touch.
Preferably, the speculum two is placed in the receiving area of the telescope, and does not block above-mentioned receiving area
Central area.
Preferably, after the reflection of speculum one and speculum two, light beam is not hiding the light beam of the beam expander transmitting
Gear telescopic central is launched on the premise of region in the receiving area of telescope.
The utility model provides a kind of optical system of optical detection devices, eliminates detection blind area, makes system by only

Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.
The structural representation of the optical system for the optical detection devices that Fig. 1 is proposed by the utility model；
Numeral represents in figure：
1st, laser 2, beam expander 3, speculum 1, speculum 25, telescope
51st, receiving area 52, central area.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Embodiment：
Shown in Fig. 1, a kind of optical system of optical detection devices, including：
One laser 1；
One beam expander 2, the beam expander 2 are coaxially disposed with laser 1；
One is used to reflect the light beam that beam expander 2 launches and with the beam expander 2 axially in the reflection of 45 degree of angles settings
Mirror 1；
One is used for the light beam launched of reflex reflector 1 and the speculum 24 being be arranged in parallel with speculum 1；
And the telescope 5 be arrangeding in parallel with the laser 1.
The laser 1 keeps certain distance to set with telescope 5, and both diameter parallels and structure are not in contact with each other.
The speculum 24 is placed in the receiving area 51 of the telescope 5, and is not blocked in above-mentioned receiving area 51
Heart district domain 52.In the present embodiment, telescope 5 is the telescope 5 with a circular reception mouth, the region that receiving port is received
For receiving area 51, the middle part of receiving port is region 52 centered on the region that is received, and the diameter of section of central area 52 is preferred
For 1/5th of receiving port diameter of section.
For the light beam that the beam expander 2 is launched after the reflection of speculum 1 and speculum 24, light beam is not blocking prestige
In transmitting in the receiving area 51 of telescope 5 on the premise of the remote central area 52 of mirror 5.
Implementation principle：Laser 1 is pulse laser 1, and the light-emitting window and beam expander 2 of laser 1 are coaxial, and laser passes through
Beam expander 2 is emitted.Beam expander 2 is parallel with telescope 5, and beam expander 2 and the decentraction of telescope 5, the overall structure of beam expander 2 are being looked in the distance
Outside mirror 5, before speculum 1 is arranged on the light-emitting window of beam expander 2, speculum 24 is arranged on and looked in the distance with beam expander 2 in angle of 45 degrees
The receiving area 51 of mirror 5, but the central area 52 of telescope 5 is not blocked.
Light beam after beam expander 2 after the reflection of speculum 1 by being mapped on speculum 24, after the reflection of speculum 24,
Light beam is transmitted into air in the direction of the diameter parallel of telescope 5, and light beam occurs Mie scattering reaction with the particulate matter in air and produced
Rear orientation light received by telescope 5.
Beam expander 2 is parallel with telescope 5, and structure is not overlapping, light beam by speculum 1 and speculum 24 twice
After turning back, do not block in the receiving area 51 of telescope 5 but central area 52 and launch.
The laser beam that laser 1 is launched then passes through speculum 1 and speculum two again by being coaxial therewith beam expander 2
4 reflection, make direction of beam propagation parallel with telescope 5, final Exit positions are in the receiving area 51 of telescope 5, speculum
24 do not block the central area 52 of telescope 5, and beam exit is into air；After with the particulate matter in air Mie scattering occurs for laser
Rear orientation light is produced, is received by telescope 5, is passed through by the optical signal that telescope 5 receives after other spectroscopical processing
Photodetector switchs to electric signal, by analyzing power and the change of electric signal, analyzes power and the change of Atmospheric Grains.
A variety of modifications to these embodiments will be apparent for those skilled in the art, herein
Defined General Principle can be real in other embodiments in the case where not departing from spirit or scope of the present utility model
It is existing.
