Description
Technical field
The invention belongs to cylinder class laser fiber solid matter scanning imagery equipment, such as optical draught machine, laser photocomposing machine, laser
The optical imaging system of direct plate maker etc., the resolution ratio changing method particularly to a kind of imaging of cylinder and its device.
Background technology
In the optical fiber close arrangement scanning system of fixed resolution, laser picture element signal passes through multichannel single mode or multimode fibre,
Sent in the form of solid matter, through the Prescription lenses group of large-numerical aperture, scaled imaging to absorption or clamping are at the uniform velocity
Film on the cylinder of rotation or plate surface.Simultaneously as the section structure of optical fiber is divided into core diameter and refraction covering, such as multimode
For 62.5/125um, laser picture element signal is only in the transmission of core diameter layer for the diameter of optical fiber ratio.So between solid matter luminous point out
It is detached, next step is imaged, in image plane, its hot spot is also detached.This substantially can not meet scanning and require.If
Expand image planes spot diameter although spot separation can be made up with the method for out of focus, but the edge quality of hot spot can be sacrificed.Also have
Scheme is to remove the surrounding layer of optical fiber so as to photoconductive layer touches together.Even if but this method success, technology difficulty can be very
Greatly, batch cost is costly.
Current solution is using the conventional detached linear array of solid matter method construct luminous point, but makes line when mounted
Array and cylinder horizontal bus keep an angle so that when spot projection in linear array is on cylinder horizontal bus, luminous point
Diameter can touch (as Fig. 1).But the linear array of an inclination can not possibly optically be realized to horizontal plane projection,
This actually require in array should synchronism output each luminous point (i.e. raster data) line asynchronous, timesharing ground recursion postpone
Output, this is accomplished by a data sequential processing device and the excitation of array luminous point is made to postpone recursion, makes all in the linear array of inclination
Being imaged onto on horizontal line of luminous point timesharing, makes luminous point with desired resolution ratio close-packed arrays and exposure.
In the use of the constant optical fiber close arrangement imaging device of number of fibers, higher imaging resolution can be obviously improved into
As details quality, but exposure entirety can be made close to proportional increase time-consuming, thus leading to the unit production capacity of equipment to decline simultaneously.
Therefore, client wishes the concrete image quality demand according to its product and capacity requirements, and autonomous real-time selection is more reasonably imaged
Resolution ratio, and rapid handover success.
From above-mentioned image-forming principle, put between pixel away from by linear array fiber cores away from, lens group enlargement ratio, line incline
Oblique angle, and data time sequence processor together decides on.And in the selection of technical scheme of resolution varying, more direct in theory
It should be the enlargement ratio of change lens group.Because the ratio of lens group multiplying power change, directly embody imaging resolution switching
Ratio, then above-mentioned remaining listed several parameter all need not be changed, and the point footpath of each pixel also can be followed simultaneously and be cut simultaneously
Change.The drawbacks of this scheme, if only the simple change on the enlargement ratio of lens group must affect its numerical aperture, thus shadow
Ring other physical parameters of lens group itself, such as depth of focus, visual field, object image distance, resolution ratio etc..This is design and the system of lens group
Design brings a difficult problem.For example, depth of focus and numerical aperture square inversely, therefore as when imaging pixel resolution from
When 8000DPI changes into 16000DPI, depth of focus will become little and must be difficult to Project Realization.
