According to one embodiment of the disclosure, a kind of projection arrangement is provided.As shown in Figs. 1-2, which includes illumination
Light source 1, reflecting prism, DMD (digital micro-mirror) module 3, rotary reflector and projection lens 5.
Reflecting prism is TIR prism 2 (total internal reflection prism) or ITIR prism 2a (total internal reflection prism).Such as Fig. 1 institute
Show, the light that lighting source 1 is incident on after being imaged in DMD module 3 is totally reflected on reflection galvanometer 4 by ITIR prism 2a.Such as Fig. 2
Shown, the incident light of lighting source 1 is totally reflected by TIR prism 2, and then light is imaged using DMD module 3.Imaging
It is irradiated on reflection galvanometer 4 after light transmission TIR prism 2 afterwards.
It is illustrated by taking ITIR prism as an example below.Lighting source 1, ITIR prism 2a and rotary reflector are sequentially set
It sets.For example, lighting source 1 can be, but not limited to, laser light source or LED light source.The light that lighting source 1 issues is RGB
Light.After the light that lighting source 1 is emitted is coupled via ITIR prism 2a and DMD module 3.It is incident to rotary reflector, and by can
Rotate reflecting mirror reflection.Light is incident to projection lens 5 after being reflected.After amplifying via projection lens 5, light is formed on the projection surface
Projected image 6.
For example, ITIR prism 2a receives the illuminating bundle that lighting source 1 is emitted, and to illumination light when being coupled
Shu Jinhang light path converting, so that illuminating bundle is incident to DMD module 3.Illuminating bundle is again incident on after the reflection of DMD module 3
ITIR prism 2a.ITIR prism 2a receives the projected light beam that exports according to illuminating bundle of DMD module 3, and to projected light beam into
Rotary reflector is emitted to after row light path converting.
DMD module 3 includes multiple rotatable micro-reflectors.The size of micro-reflector determines the pixel of projective module group.
Each micro-reflector can reflect light.DMD module 3 includes opening, closing two states.When opening, DMD module 3
Illuminating bundle from ITIR prism 2a is reflected.When in off position, DMD module 3 rotates, to will not reflect
Illuminating bundle.Opening, the state of closing of multiple micro-reflectors are same or different.
Rotary reflector includes mirror body and driving device.Driving device is for driving mirror body to turn around first axle and the second axis
It is dynamic.For example, mirror body is plane mirror.Projected light beam is irradiated in mirror body, and is reflected by mirror body.
Certainly, in other examples, mirror body is convex mirror or concave mirror.The work for making pixel-shift can be equally played in this way
With.
As shown in figure 4, rotary reflector is configured as under conditions of DMD module 3 is opens, it can be reciprocal around first axle
Rotation, and delay set duration around the second axis reciprocating rotation, so that single pixel is perpendicular to first axle and perpendicular to second
Axis direction is extended.For example, reciprocating rotation refers to rotary reflector relative to first axle or the rotation setting of the second axis unilateral side
Angle returns again to the initial position relative to respective axis.
For example, as shown in figure 4, first axle is x-axis.Second axis is y-axis.Rotary reflector is reflection galvanometer 4.Reflection vibration
Mirror 4 includes MEMS device and reflecting mirror.MEMS device is driving device.Reflecting mirror is mirror body.For example, reflecting mirror is rectangle, circle
Shape, ellipse etc..MEMS device drives reflecting mirror to rotate around x-axis, y-axis.Certainly, the material of mirror body is not limited to glass, can be with
It is metal etc..
By taking the reflecting mirror of ellipse as an example.X-axis, y-axis are located at the short axle and long axis of reflecting mirror.This make reflecting mirror around
X-axis, y-axis rotation can be more balanced.Reflecting mirror is more balanced to the extension effect of projected light beam.
As in Figure 3-5, reflection galvanometer 4 is first rotated around x-axis to side.Pixel in projected image 6 occurs perpendicular to x-axis
Offset.At this point, due to the delay effect of human eye, therefore a pixel-expansion is two pixels.The distance between two pixels should make
Two pixels can be distinguished by obtaining human eye.
For example, single pixel is being half of picture perpendicular to first axle and the distance being extended perpendicular to the second axis direction
Element.Distance, that is, offset of the extension.When offset is half-pixel, the distance of the neighbouring pixel of the pixel distance is also half
A pixel.Human eye can distinguish the pixel of offset and original pixel and neighbouring one other pixel, without will be considered that and other
Pixel is to be overlapped.
Certainly, the distance of extension is not limited to half-pixel, can be the distance slightly close or slightly remote apart from original pixel, only
Want human eye that can distinguish the pixel of offset and other pixels.
Then, it is rotated further around y-axis to side after delay setting duration.Pixel shifts perpendicular to y-axis.At this point, due to
The delay effect of human eye, therefore a pixel is expanded again.It should be noted that the distance of pixel-shift half-pixel, that is, extend
A pixel out.
Next, reflection galvanometer 4 returns back to initial position around x-axis.At this point, the rotation around y-axis is still located at deviation initial bit
The position set, therefore a pixel is extended again.
Finally, reflection galvanometer 4 returns back to initial position around y-axis.Due to the delay effect of human eye, people can see four pictures
Element, rather than a pixel.
In the embodiments of the present disclosure, rotary reflector is rotated around first axle and the second axis, to carry out to projected light beam
Quickly scanning.Pixel is incident on rotary reflector.As rotary reflector is swept around first axle and the quick of the second axis
It retouches, and after rotary reflector reflects, projected light beam is quickly moved perpendicular to the first axis direction and perpendicular to the second axis direction
It is dynamic.Using the delay effect of human eye, a pixel is extended to multiple pixels, to reach the effect of extension pixel resolution
Fruit, and then the resolution ratio of projected image 6 is effectively promoted.
Rotary reflector is less than or equal to human eye delay effect around the total duration that first axle and the second axis do reciprocating rotation
Duration.In this way, in the delay Effect time of human eye, people it can be seen that by a pixel-expansion at multiple pixels.
In other examples, by the way that the rotating manner of rotary reflector is arranged, projection arrangement can be expanded by a pixel
Exhibition is 2,3,5 or more pixels.
In one example, first axle and the second axis are vertical.The case where compared to two axis out of plumb, in rotatable reflection
When mirror is rotated, two vertical set-up modes of axis make the distance between two adjacent pixels bigger, and multiple pixels are more
It is easy to distinguish, rather than coincides together.
In one example, as shown in fig. 6, the period that rotary reflector is rotated around first axle is the opening of DMD module 3
Duration.Rotary reflector is identical as the period rotated around the second axis around the period that first axle rotates.
In general, DMD module 3 undergoes a high level and low level is a cycle.In high level, DMD
Module 3 is in an open state；In low level, DMD module 3 is in off state.Opening state and the duration of closed state are equal.
By taking rotary reflector is moved around first axle turn (for example, x-axis) as an example.When being in high level, galvanometer 4 is reflected around x
Axis rotates θ radian (for example, relative to initial position)；When being in low level, galvanometer 4 is reflected around x-axis rotation-θ radian.First
When beginning position, projected light beam is vertical with the plane of incidence.
Preferably, rotary reflector does the radian of reciprocating rotation around first axle and does the radian of reciprocating rotation around the second axis
It is identical.That is, reflection galvanometer 4 rotates θ radian (for example, relative to initial position) around y-axis when being in high level；In low
When level, galvanometer 4 is reflected relative to y-axis rotation-θ radian.In this way, the line of four pixels is square, can
Guarantee that image planar extends more evenly.
In this example embodiment, the period and be DMD around the period of the second axis rotation that rotary reflector is rotated around first axle
The half in 3 period of module.Rotary reflector around the first axle do reciprocating rotation initial time and the DMD module
3 opening moment is identical.Rotary reflector around the second axis rotate relative to the delay rotated around first axle when it is a length of itself week
The a quarter of phase.This makes the rotation of rotary reflector, stopping synchronous with the opening of DMD module, closing.
In this example embodiment, as shown in figure 3, reflection galvanometer rotates θ radian, then the light reflected rotates 2 θ radians.Single picture
Element is being calculated as Δ y perpendicular to first axle and perpendicular to the distance of the extension of at least one of the second axis direction.It can be obtained by Fig. 3
Out,
Δ y=L × tan (2 θ)
Since 2 θ are the radians of very little, above-mentioned formula can be similar to: the θ of Δ y=L × 2
Wherein, θ is the radian that rotary reflector is rotated relative to initial position；L is rotary reflector and projection lens
The distance between head.
In one example, the size of a pixel of DMD module 3 is 5.4 μm.Half-pixel is stored as 2.7 μm.
That is, y=2.7 μm of Δ.In general, L is known.θ can be calculated according to above-mentioned formula.
As seen in figs. 5-6, the course of work of the projection arrangement is as follows:
S1, start when, DMD module 3 be high level, i.e., DMD module 3 be opening state.Galvanometer 4 is reflected around x-axis
Rotation is in high level, i.e., reflection galvanometer rotates θ radian around x-axis (relative to initial position).At this point, the delay due to human eye is imitated
It answers, so that pixel translates up half-pixel (i.e. 2 θ radians).
S2, after postponing a quarter period, reflection galvanometer 4 start around the rotation of y-axis, and be in high level, that is, reflect
Galvanometer continues around y-axis rotation θ radian on the basis of around θ radian is rotated around x-axis (relative to initial position).Due to x-axis and y
Axis is vertical, therefore projection arrangement is in the pixel basis of extension, then to right translation half-pixel.
S3, reflecting after around the half period that x is rotated, rotation and DMD module 3 of the galvanometer 4 around y-axis are still electric for height
It is flat.Galvanometer 4 is reflected to keep rotating θ radian around y-axis (relative to initial position).And the rotation for reflecting galvanometer 4 around x-axis is in low electricity
Flat, i.e., rotation radian is-θ, and reflection galvanometer 4 is made to reach the initial position around x-axis rotation.On the basis of the above, pixel is put down downwards
Move half-pixel.
S4, after 3/4ths periods by being rotated around x, DMD module 3 still be high level.Galvanometer 4 is reflected around y-axis
Rotation and be low level around the rotation of x-axis.Galvanometer 4 is reflected around y-axis rotation-θ radian, reaches reflection galvanometer 4 around y-axis
The initial position of rotation.So that pixel is to left half-pixel.
When DMD module 3 is in low level, reflection galvanometer 4 does not rotate.Due to the delay effect of human eye, people can see
Four pixels.
Pixel-expansion shown in Fig. 5 is the extension carried out along clockwise direction in first quartile.In other examples,
When the rotation direction for reflecting galvanometer 4 changes, the extension carried out at second and third, in four-quadrant can also be.The side of extension
To be also possible to counterclockwise.
