Rate.
Description of the drawings
Fig. 1 is a kind of knot of laser new line display optical system in windshield imaging of the utility model preferred embodiment
Structure schematic diagram；
Fig. 2 is that the utility model preferred embodiment is a kind of micro- in the laser new line display optical system of windshield imaging
The structural schematic diagram of lens array.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of laser new line display optical system being imaged in windshield is present embodiments provided,
The laser new line display optical system includes：
Laser light source 20；
The microlens array 50 being oppositely arranged with the laser light source 20；
It is oppositely arranged with the microlens array 50, for reflecting the first reflection across 50 light of the microlens array
Mirror 30；
It is oppositely arranged with first speculum 30, for reflecting the second speculum from 30 light of the first speculum
40；And
It is oppositely arranged with second speculum 40, for reflecting the windshield from 40 light of the second speculum；
The microlens array 50 is two, and 50 crowning of the microlens array is oppositely arranged.
Specifically,
Preferably, the laser light source 20 includes three color micro laser head of red, green, blue.
Preferably, the laser new line display optical system further includes：
The tumbler being connected with first speculum 30 and second speculum 40.
Preferably, first speculum 30 and second speculum 40 are plane mirror, concave spherical mirror, concave aspherical surface mirror
Or free-form curved mirror.
Specifically, the program by microlens array 50, laser light source 20, the first speculum 30, the second speculum 40 with
And windshield realizes the head-up-display system on vehicle.In said program, laser light source 20 includes three color micro of red, green, blue
Laser head in the beam emissions to MEMS micromirror that laser head is sent out, by the angle tilt of MEMS micromirror, makes different colours light beam
Hybrid projection is on camera lens, to realize full-color display.
Microlens array 50：It is made of in opposite directions two identical convex microlens arrays 50, sees attached drawing.Microlens array 50 connects
The light beam that laser lens project is received, image is generated.The reason is that two convex microlens arrays 50, the work with optically focused imaging
With.
It should be noted that being the prior art about the principle that microlens array 50 is imaged, nor this programme needs to protect
The content of shield, therefore do not repeat herein.
First speculum 30：For light path of transferring, reduce system dimension.
Second speculum 40：Image on microlens array 50 is reflected by the first speculum 30 and the second speculum 40
The virtual image 60 is generated afterwards.Determined by the first speculum 30 and the second speculum 40 at the distance and 60 size of the virtual image of the virtual image 60.The
Two-mirror 40 can adjust its angle by rotating mechanism, so that image can move up and down, to which the people of different heights can look for
To best image space.
The relative distance and angle of first speculum 30 and the second speculum 40 are designed according to primary car structure so that imaging away from
