Abstract
The utility model provides a kind of optical detector based on fiber array, belong to optical-fibre communications field, including a fiber array and a detection array, the fiber array includes at least two optical fiber arranged side by side, the detection array includes at least two detecting heads arranged side by side, and optical fiber is corresponded with detecting head.Compared with prior art, the optical detector, by corresponding optical fiber side by side with detecting head side by side, the light that optical fiber is sent out can be detected head reception completely, achieve the purpose that light monitoring detection；Coupling efficiency is high, and all optical-fibre channels couple simultaneously, can disposably couple N >=2 channel；Entire optical detector overall appearance size reduction, improves detection channels quantity, reduces cost of manufacture.
Description
Technical field
The utility model is related to optical-fibre communications field, especially a kind of optical detector based on fiber array.
Background technology
As shown in Figure 1, collimator and light that existing optical detector is made of 1, lens 2 of a single fiber tail optical fiber are visited
It surveys the photodetector that chip 3 forms to be formed, is then forming detection array by N number of such individual devices.However, this
The existing product appearance size of kind is too big, and cost of manufacture is too high.
Utility model content
Too big for existing optical detector apparent size, the high problem of cost of manufacture, the utility model provides a kind of base
In the optical detector of fiber array, apparent size is reduced, improves detection channels quantity, reduces cost of manufacture.
The technical solution adopted in the utility model is：
A kind of optical detector based on fiber array, including a fiber array and a detection array, the optical fiber
Array includes at least two optical fiber arranged side by side, and the detection array includes at least two detecting heads arranged side by side, light
It is fine to be corresponded with detecting head.
Preferably, the spacing between the spacing between adjacent fiber and detecting head is identical.
1. compared with prior art, the beneficial effects of the utility model are：The utility model provides a kind of based on optical fiber
The optical detector of array, by corresponding optical fiber side by side with detecting head side by side, the light that optical fiber is sent out can quilt completely
Detecting head receives, and achievees the purpose that light monitoring detection；Coupling efficiency is high, and all optical-fibre channels couple simultaneously, disposably can be with coupling
Close N >=2 channel；Entire optical detector overall appearance size reduction, improves detection channels quantity, reduces cost of manufacture.
Description of the drawings
Fig. 1 is the schematic diagram of optical detector in the prior art；
Fig. 2 is a kind of schematic diagram of the optical detector based on fiber array provided by the utility model.
Specific implementation mode
Preferred embodiment provided by the utility model is illustrated with reference to the accompanying drawings.
Fig. 2 is a kind of preferred embodiment of the optical detector based on fiber array provided by the utility model.Such as Fig. 2
Shown, which includes a fiber array 10 and a detection array 20, the fiber array 10 include at least
Two optical fiber 11 arranged side by side, the detection array 20 include at least two detecting heads 21 arranged side by side, optical fiber 11 and spy
Gauge head 21 corresponds, and the spacing between adjacent fiber 11 is identical as the spacing between detecting head 21, and the light that optical fiber 11 is sent out can
It is received with completely detected head 21, achievees the purpose that light monitoring detection；The coupling efficiency of entire optical detector is high, and all optical fiber are logical
Road couples simultaneously, can disposably couple N >=2 channel；Entire optical detector overall appearance size reduction, improves detection channels
Quantity reduces cost of manufacture.
In conclusion the technical solution of the utility model sufficiently effective can realize above-mentioned purpose of utility model, and this
The structure and the principle of work and power of utility model have all adequately been verified in embodiment, can reach expected effect and mesh
, under the premise of without departing substantially from the principles of the present invention and essence, numerous variations can be made to the embodiment of utility model
Or modification.Therefore, the utility model includes all replacement contents that all are previously mentioned in patent claim in range, any
Equivalence changes made by present utility model application the scope of the claims, all within the scope of the claims of category this case application.
