Description
Technical field
Outside the present invention relates to the auxiliary device of solar irradiance monitor, more particularly to a kind of solar irradiance monitor visual field
Stray light suppression device.
Background technology
The sun is the energy source of earth system, each dynamic process of earth system is driven, from Atmospheric processes to ocean
Stream circulation, long-term climatic variation is changed to from Short-term Weather, solar radiation all has for earth ecology circle or even human society
There is wide influence.Solar irradiance monitor is the scientific instrument for monitoring exoatmosphere total solar irradiance change, it can
With the high-precision sun solar global irradiance data obtained for a long time, scientific basis is provided for research climate change.
Veiling glare is produced through the improper light path such as internal system optical element or structural member surface multiple reflections, refraction
A kind of harmful light, it will usually cause ssystem transfer function reduce, ambient noise increase, contrast decline etc. adverse effect.It is right
For solar irradiance monitor, the change in long term rate of total solar irradiance is for 0.3% or so, it is necessary to which instrument reaches better than 0.01%
Uncertainty of measurement.It is stringent to control veiling glare to seem particularly critical to ensure Instrument measuring precision.
The method for usually suppressing veiling glare is to introduce the spuious photo structure that disappears for system, i.e., the veiling glare that disappears is added in system light path
Diaphragm, but if the application environment of instrument changes, such as interference of installation site, neighbouring Other Instruments, introduces new
Veiling glare source, generally requires to redesign diaphragm for eliminating stray light, causes the lead time for newly grinding instrument to extend, causes inheritance
The state change of instrument and be difficult to qualitative assessment its influence, especially for solar irradiance monitor, systematic survey light will be caused
Road, the change for measuring thermal environment, serious adverse effect is brought to data measurement accuracy.
The content of the invention
It is contemplated that at least solve one of above-mentioned technical problem, there is provided one kind can eliminate solar irradiance monitor use
Adverse effect caused by the veiling glare brought when environment changes, and can ensure the measurement accuracy of solar irradiance monitor
Stray light suppression device outside solar irradiance monitor visual field.
To achieve the above object, the present invention uses following technical scheme：
The present invention provides stray light suppression device outside a kind of solar irradiance monitor visual field, including along light path incidence side
To preposition shading diaphragm, diaphragm for eliminating stray light and the solar irradiance monitor reception cavity set gradually, the preposition shading diaphragm
Nothing blocks the maximum field of view that visual field is more than the solar irradiance monitor reception cavity；The preposition shading diaphragm is cylindrical in shape, described
Preposition shading diaphragm includes at least two panels diaphragm；The diaphragm for eliminating stray light is cylindrical in shape, and the diaphragm for eliminating stray light includes at least two panels
Diaphragm, the minimum clear aperture at least two panels diaphragm of the preposition shading diaphragm are more than at least the two of the diaphragm for eliminating stray light
Maximum clear aperture in piece diaphragm；All diaphragms of the preposition shading diaphragm are respectively positioned on the solar irradiance monitor and receive
The outside of the maximum field of view of chamber.
In some embodiments, the inner surface of preposition shading diaphragm scribbles pitch-dark material coating.
In some embodiments, the preposition shading diaphragm is made of 3 diaphragms, along light path incident direction, 3 diaphragms it is logical
Optical port footpath is sequentially reduced.
In some embodiments, along light path incident direction, first diaphragm and second diaphragm of the preposition shading diaphragm
Between interval be more than interval between second diaphragm and the 3rd diaphragm.
In some embodiments, the diaphragm for eliminating stray light is made of 5 diaphragms, along light path incident direction, the thang-kng of 5 diaphragms
Bore is sequentially reduced.
In some embodiments, in 5 diaphragms, the interval between two neighboring diaphragm is equal.
In some embodiments, the incident absorptivity of the pitch-dark material coating is 0.90-0.95.
The beneficial effects of the present invention are：By in diaphragm for eliminating stray light front end, i.e., before the front end of light path incident direction is set
Shading diaphragm is put, and all diaphragms of preposition shading diaphragm are respectively positioned on outside the maximum field of view of solar irradiance monitor reception cavity
Portion, does not block the effective viewing field of solar irradiance monitor reception cavity completely.Meanwhile the preposition shading diaphragm of tubular and the veiling glare light that disappears
The design of door screen, coordinates preposition shading diaphragm and diaphragm for eliminating stray light all to include at least two panels diaphragm；So, it is ensured that veiling glare passes through
When crossing preposition shading diaphragm, at least through barrel and diaphragm front surface or rear surface absorb twice after, enter back into disappear it is miscellaneous
Light diaphragm；Likewise, in diaphragm for eliminating stray light, veiling glare also will enter back into solar radiation after absorbing reflection at least twice
In monitor reception cavity.Thus greatly reduce application environment and change the stray light brought, ensure that solar radiation monitors
The measurement accuracy of instrument.
