Abstract
The utility model relates to a super high resolution radio super high speed laser holographic cutting and recording machine, which is composed of a laser, a shutter, a beam expansion shaping lens, a matrix light valve, a spectroscope, a focusing imaging lens, laser holographic recording medium, etc. The vicinity of the spectroscope (either the front or the rear is acceptable, but the front side of the spectroscope is preferred) is provided with an area array light valve, and the opening and the closing (the regularities of distribution of time and space) of a small pixel switch in the light valve is controlled by a computer. The utility model has the characteristics of ultrahigh resolution, super high speed and short making period. The utility model is especially suitable for making true color pictures with continuous varying luminance and chrominance.
Description
The utility model belongs to CD writer, is a kind of ultrahigh resolution hypervelocity laser hologram CD writer specifically.
Existing laser holography is being used for that plane picture and text recording of information mode is had two kinds of diametrically opposite roads: a kind of be early, the also mode of more or less freely realization simultaneously, exactly laser beam is enlarged, do large-area exposure record.This method is being made some when having the picture and text of very strong dynamic sense, poor effect; Another kind is the technical method that just developed in recent years, and the bundle that exactly laser beam contracted focuses on, and picture and text is carried out the pointwise formula of lining by line scan write down (being called for short " photoetching ").This method has obtained development rapidly owing to have the dynamic powers that the aspect showed such as image in making, and constantly perfect along with technology, and Fresnel is encrypted and accurate three-dimensional image etc., also can make of the pointwise photoetching process.But, and require bifocal on the record interface, to overlap fully because this method is that twin-beam is focused on.Therefore, along with the raising to resolution requirement, technical difficulty is also strengthening.Main problem be along with resolution raising (containing the literal that micro is encrypted) as requiring to carve and to the increasing of the complexity of dynamic image layout, with point by point scanning photoetching mapping, its macroscopic velocity has just slowed down.
The purpose of this utility model provides a kind of ultrahigh resolution hypervelocity laser hologram CD writer, both improving spatial resolution, satisfying image when dynamic layout difficulty requires, improve again photoetching sweep velocity, shorten fabrication cycle, finish the work with getting twice the result with half the effort.
The utility model is achieved in that a kind of ultrahigh resolution hypervelocity laser hologram CD writer of being made up of laser instrument, shutter, expansion bundle shaping mirror, spectroscope, focal imaging lens, laser holographic recording medium successively, near its spectroscope (can before can after, but preferably in the spectroscope front) light valve-matrix light valve of a face battle array is installed.Pixel P cock in this light valve is controlled its opening and closing (time and spatial distributions rule) by computing machine.In the utility model,, can make those brightness and colourity and have continually varying true color picture as long as use acousto-optic modulator to substitute spectroscope by computer-controlled four light beams.
The utlity model has following advantage: ultrahigh resolution, hypervelocity, shorten the fabrication cycle characteristics.Compared with prior art, the utility model utilizes the matrix light valve to adopt the multiple beam technology of exposure synchronously, if will finish a breadth long-pending is that 1 square of inch, resolution are the comparatively photoetching making of complex image of 2000dpi, dynamic layout, macroscopical sweep velocity of photoetching can improve 10～100 times, total time-consuming only be original 10%～1%.The utility model also is particularly suitable for making those brightness and colourity has continually varying true color picture.
The utility model has following accompanying drawing:
The light path sketch of Fig. 1 laser hologram CD writer of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Embodiment 1:
As shown in fig. 1,1 is laser instrument: can be the laser instrument of gas, solid or semiconductor material, wavelength be in visible or invisible scope; 2 are shutter: can be the shutter of mechanical, electromagnetic type, electrooptical modulation or acoustooptic modulation, be subjected to computer control; 3 for expanding the bundle shaping mirror; 4 for the matrix light valve: can be liquid crystal light valve, transmission-type or carry on the back trans LCD panel, integrated electric photomodulator (plate), microreflection minute surface battle array plate.Opening or closing of each pixel in the matrix light valve all is subjected to computer control; 5 is spectroscope: machine engraving or holographic low frequency grating also can be acousto-optic modulators (beam split), and they are fixed on the stepper motor of energy quick rotation, and by its corner of computer control; 6 is the focal imaging lens; 7 are the laser holographic recording medium: photoresist, dichromated gelatin, photoconduction static thermoplastic and the inversion of phases film based material that can be silver salt, photopolymer, photolysis type are applied on the flat board, place by computer-controlled stepper motor again and do the motion of x-y two dimensional surface.Near the spectroscope 5 (can before can after, but preferably in the spectroscope front) light valve 4 of a face battle array of installation.Matrix light valve 4 adopts special tailor-made transmissive liquid crystal display plate (screen), is made up of 32 * 32 pixels; It is square that Pixel Dimensions is about 0.2mm * 0.2mm; Contrast (contrast factor) is more than 1: 10; Switching response speed is less than 40ms.The established angle of liquid crystal matrix light valve should make the polarization direction of light valve consistent or vertical with the polarization direction of illuminating laser beam.The opening and closing of the pixel P cock in this light valve 4 (time and spatial distributions rule) are controlled by computing machine.
Difference from Example 1 is, uses by computer-controlled four light beam acousto-optic modulators and substitutes spectroscope 5, and its outgoing beam is divided into the reference beam of not deflection (straight penetrate type) and the object beam of ultrasonic deflection.Object beam is divided into three light beams, writes down red (R), green (G) in the true color image, blue (B) three primary colours respectively.On behalf of three beams (deflection) reference light of RGB and the deflection angle of (direct transmission light) thing light, the size of deflection angle and photoetching machine lens relating to parameters in this example, be respectively 1.7 °, 2.0 ° and 2.3 °.Can make those brightness and colourity like this and have continually varying true color picture.
