Point light source begins to irradiate, the corresponding pixel of a point light source, and is imaged simultaneously by tens even more beam spot light sources, often
Secondary to be formed simultaneously tens even more pixels, the light that multi beam point light source issues uniformly is collimated flat in coke by optical lens
Face imaging controls to form large format high accuracy number image by the way that motion platform is mobile with accurate light source synchronous.
It further, further include that platform motor is moved left and right the platform equipped with multi beam point light source is controlled, every time
Moving distance is individually as the length or width of several points, and row is as the number that number is that the times N that platform motor moves left and right multiplies point light source
Measure S.
It further, further include that platform motor is moved up and down the platform equipped with multi beam point light source is controlled, every time
Moving distance is after the movement in place of platform motor, to be imaged in the way of row imaging individually as the length or width of several points,
The total pixel of image multiplies the number that platform motor moves up and down for the quantity S that the times N that platform motor moves left and right multiplies point light source
M。
Further, further include carrying out being initialized to picture in the leftmost side of object, be then successively imaged to the right, when
After whole horizontally-arranged imaging, platform motor is moved up and down, and vertical setting of types is successively successively imaged in sequence, until digital picture is aobvious
Show completion.
It further, further include moving left and right the digital imagery initialization first step by several multi beam point light sources, initial
Position is imaged, and motor is controlled after image has been formed and carries out transverse shifting, second step is moved to and is imaged, when motor moves
After moving three times, the digital picture of row direction is completed with showing.
It further, further include moving up and down digital imagery initialization to move down third step imaging, initial
Position carries out the 4th step of imaging, carries out transverse shifting after the completion of imaging and the 5th step is imaged, after six steps is completed in horizontally-arranged imaging again
Continue to move down then repetitive cycling, circulation route is S-shaped, and the mode of the similar scanning of whole process carries out high speed imaging.
(3) beneficial effect
The present invention compared with prior art, has the advantages that the digitized map of the invention based on multi beam point light source
As production method, directlys adopt synchronously control multi beam point light source and moved to form digital picture, more efficient, speed is fast,
And light source direct projection forms image, without misalignment angle, image is indeformable, so invention can more be suitble to industrial application.
