Description
Technical field
The present invention relates to airborne display field, more particularly to the laser-projector with night vision compatible function.
Background technology
The light source of projecting apparatus is roughly divided into three kinds on the market at present：Bulb (high-pressure sodium lamp, xenon lamp etc.), LED, laser.
Wherein, the cost of bulb is low, but its short life, and brightness decay is very fast.LED life hours up to ten thousand, but brightness is not enough maximum
Drawback, light source technology bottleneck is obvious, and green LEDs efficiency is low, and need to such as increase the more multiple light sources of brightness need, weak heat-dissipating,
It is unfavorable for the application of highlighted miniaturization.The life-span of LASER Light Source is at least 20000 hours, and brightness and colour gamut also have a clear superiority,
And ensured by the sealing for setting considering security of miniaturization, the security of LASER Light Source.Using the projecting apparatus of LASER Light Source
Almost can instantaneous starting, reach operating brightness, can high-speed switch machine；And work is needed for a period of time could during conventional bulb start
Reach stable operating brightness.Current Color Laser Projection Technology is generally divided into two kinds：RGB laser projections and the projection of laser fluorescence powder
Technology.Wherein, RGB laser projections cost is higher, and tri- kinds of LASER Light Sources of RGB all have coherence, at present can not be from root
Solve, also with the temperature change in the course of work color drift can occur for RGB laser.Laser fluorescence powder technology is then to use
One-wavelength laser blendes together white light by color phosphor colour wheel, no speckle effect, and the technology obtains generally in cinema at present
Using.
Laser has huge advantage in airborne projection field, but due to airborne particular/special requirement, at present by laser projection
Technology is applied in airborne circumstance, it is necessary to solves the problems, such as night viewing compatible.Night viewing compatible, i.e., any shiner in aircraft cabin
Body will not Night Vision Imaging System be interferenceed, and keeps bore hole can with NVIS (Night Vision Imaging System)
See.In the case of night flight, pilot needs to wear low-light level night vision device to perform the tasks such as flight, investigation aircraft.If without any
The light source such as processing, incandescent lamp, display in cabin can send infrared and near infrared band light, and the work of low-light level night vision device
Make spectral region just between 630nm to 940nm.So in the case where wearing low-light level night vision device, these are infrared and near red
The light of wave section can interfere to pilot, produce the flash lamp effect in the case of similar bore hole, reduce night vision imaging
The readability of system, it can not be received and recognized low-light information, or even pilot can be made to feel dizzy, cause flight hazard,
It can not meet that night operations and flight require.Therefore, need to meet night viewing compatible applied to the shadow casting technique under airborne circumstance
It is required that just can guarantee that pilot can in night safe, be effectively carried out task.
Therefore it provides a kind of laser-projector with night vision compatible function is applied in terms of airborne Display Technique very
It is necessary.
