Description
Technical field
It is the present invention relates to field of photoelectric technology, in particular to a kind of for carrying out the survey of high/low temperature illumination to gleam image intensifier
The gleam image intensifier test macro of examination.
Background technique
Gleam image intensifier is mainly made of high voltage power supply and image intensifier tube two parts, belongs to high-voltage electric vacuum device,
There is important application in the fields such as military affairs, scientific research.Application in reality often requires that image intensifier being capable of normal work in extreme circumstances
Make and there can be no any problems, it is therefore desirable to using the variable test system of variable temperatures, illumination to image intensifier
Quality is tested.
For the reliability for the high voltage power supply examining image intensifier and its using, in actual production, usually first
The high and low temperature test is carried out with power supply the high and low temperature test system against high voltage power supply, if high voltage power supply test passes, by the high-voltage electricity
Source connects with image intensifier tube and forms image intensifier, is then carried out again with image intensifier the high and low temperature test system to the image intensifier
The high and low temperature test.Two sets of different test macros are used before and after this method, therefore testing process may be excessively complicated, occupies more
Resource, in addition there is likely to be problems below:
1. when carrying out output test to high voltage power supply, since high voltage power supply output is up to 10kV, insulation processing requirement is high,
It is very sensitive to humidity simultaneously, electrion easily occurs in high humidity environment.In existing high-low temperature test chamber, for high pressure
The safeguard measure of electric discharge is that the high-voltage output line of high voltage power supply is put on to insulation sheath to draw by the hole on chamber door again mostly,
Then it is connected with outer testing system, it is closed using cork at hole.However, temperature is possible to low when carrying out low-temperature test
To -55 DEG C hereinafter, cork is likely due to contract on cooling and hole can not be fully sealed at this time, cause to be easy to appear mist in cabinet
Phenomena such as gas, condensation or frosting, is also easy to happen electrion although output line is cased with insulated hull at this time, to Hi-pot test
Have an adverse effect.In addition, light input and image intensifier fluorescent screen output brightness precise measurement can also be seriously affected by hazing in case.
2. the function of image intensifier is to enhance faint light to adapt to eye-observation, therefore need to use when test
The light of external different illumination is supplied to image intensifier cathode by light source, while need to be carried out to the light luminance that image intensifier exports real
When monitoring record.Existing light source design is usually that light source module is placed in outside high-low temperature chamber, is then embedded in height by one
Light is passed to booster cathode by the cylindrical glass pipe on cryogenic box tank wall hole.It, every time can only be right using this method
One image intensifier is tested, and test job efficiency is very low.
3. the input light of existing different illumination intensity is chosen by optical filter, the anti-dazzling screen of differential declines
, it can be achieved that intensity of illumination range it is relatively narrow, and can not accomplish illumination linear change, it is automatic with program setting to can not achieve illumination
Variation is unfavorable for scientific research and knows the real situation test.In addition, original output luminance test module is that photoelectric conversion test module is placed in height
In cryogenic box, luminance test module and image intensifier are put together and carry out thermocycling, during test, luminance test mould
Block is affected by high/low temperature, and test result error is relatively large.
4. test data record aspect, existing test macro generally use the output light of pin hole printer record image intensifier
The brightness of line.But pin hole printer high failure rate, whole system complexity is huge, and registered depth is limited, such as does to image intensifier
Several hours depth registrations will consume a large amount of paper.And such test macro sample rate is low, it is difficult to capture sporadic
