Visible ray DMD device 12 and short-wave infrared DMD device 22 can use the DMD DMD of TI companies
（Digital Micromirror Device）, the scale selection 1920 × 1080 of device, pixel dimension is 10.8 μm.DMD shows
Show that part is made up of micro reflector array, each micro-reflector can be with the respective deflection state of independent control.
DMD micro mirror is stationary in "ON" state and "Off" state, then 1 bianry image is shown in DMD.DMD will show
Show 8 gray level images, then gray modulation is carried out to DMD.The general principle of gray modulation is that detector has the time of integration, is led to
Cross control DMD and show that the gray level image cycle is less than the time of integration of detector, then the gray level image that detector is shown to DMD is present
" persistence of vision " characteristic.
Furthermore it is preferred that the embodiment also includes visible ray transfer 14 and short-wave infrared transfer 24.Visible ray turns
It is arranged on to device 14 between visible light source 11 and visible ray DMD device 12；Short-wave infrared transfer 24 is arranged on shortwave

Light by ellipsoid reverberation bowl 7 reflecting focal in the second focal point, light pipe 8 is arranged on the second focal point.Square rod is illuminated
System is simple in construction, cheap because of its, and circular light beam is transformed into rectangular light while realize to high efficiency, high uniformity again
Beam, therefore the light-output for being converged the focus using light pipe 8, the light that such xenon source is sent just are evenly distributed in product
On the other end for dividing square rod 8.
Foregoing transfer can use the light path form of class doubly telecentric light channel structure, and the incident light chief ray of each visual field is put down
Row in the axis of light pipe 8, and emergent light focal plane and optical axis into 24 ° of angles.Such optical system ensures emergent light key light
The light beam that line impinges perpendicularly on each visual field on DMD speculums has identical incidence angle, therefore either on state of or dark-state,
All there is preferable irradiate uniformity on chip face.The given of transfer index will consider the output end light beam of light pipe 8
The factors such as size, the size of dmd chip, the F numbers of projection lens, the difference major control aberration of the system, it is to avoid transmission distance

Wave band, includes infrared quartz JGS-3, sapphire, calcirm-fluoride etc. in the selectable optical base-substrate material of the wave band.Due to dichroic
The size of optical filter 4 has reached nearly 200mm x 200mm, it is contemplated that difficulty of processing, the physical and chemical stability of material, material and processing
The factors such as cost, JGS-3 is more reasonably to select.
In visible and short infrared wave band, conventional optical film materials are based on metal and conductor oxidate.For
Low-index material, SiO2It is widely used because of its good optical characteristics and technology stability；High-index material is optional
Select TiO2, Nb2O5, Ta2O5Deng TiO2Because it has larger absorption in visible near ultraviolet band and influences optical efficiency, Ta2O5Then
Because refractive index is relatively low and make it that film layer is inefficient, and Nb2O5It is preferable selection.
In addition, the dichroic filter 4 requirement is it will be seen that optical band（0.4~0.8 μm）And short infrared wave band（1.0~
2.3µm）Spectrum separation, 45 ± 10 ° of 4 operating angle of dichroic filter.According to the transition between waveband width and two wave bands
Regional analysis, " anti-visible infrared " is visible light wave range reflection, and the scheme of short infrared wave band transmission is more excellent.
It can be seen that optical projection device 13 and short-wave infrared projection arrangement 23 are using high-precision projection lens.Will according to technical indicator
Ask, projection is than 2.7, operating distance 3000mm, and the angle of visual field for calculating visible ray and infrared projection camera lens is 21 ° × 11.7 °, then
According to the specification of dmd chip, 1920 × 1080,10.8 μm of unit size, focal length is can be calculated for f=56.58mm.Projection lens
Similar to common photographic film in optical design method, optical texture and optical property, upper using, it is equivalent by mirror for taking photograph
Head image is out of position, so as to realize that the amplification of image is shown.
Projection lens is in design, the given modulation for needing to consider dmd chip parameter and projection optics camera lens of the F numbers of system
Transmission function.According to+12 ° of dmd chip ON state, -12 ° of OFF state, it can calculate and obtain the F numbers of projection arrangement and should be greater than 2.4, if
The light of light source may be still transmitted on projection screen 6 by projection lens when -12 ° of 0 ° of less than 2.4 flat states and OFF state.According to boat
The experience of the electro-optical system of its application, the overall optical transfer function value of electro-optical system is greater than more than 0.2~0.3, therefore light
To ensure the optical transfer function value of optical system more than 0.4 when learning system design.According to system F numbers and Systems Theory optics
The relation of functional limit, it is seen that the F numbers of optical projection device 13 and short-wave infrared projection arrangement 23 are set as F=4.
In addition, the design of projection objective uses telecentric beam path in image space, it is ensured that system illuminance of image plane it is uniform, while project thing
The distortion of mirror requires very high, and to ensure that the anamorphose amount launched is small, systematical distortion is typically within 2%.Projection lens is used should
The light of the light source reflected on dmd chip uniformly can be transmitted on screen by mode, form good image effect.
