Compared with the prior art, the television line chart board has the advantages that the television line chart board can quantitatively test the resolving power of an optical system to be tested, has good universality, low cost and chart information, can not limit the focusing distance due to chart sizes, can more clearly express the imaging conditions of a tested region, is not limited by pixel sizes and definition, and is more suitable for volume production.
Description
Technical field
The utility model relates to the test and the Performance Detection chart plate of photoelectronic imaging instrument, relates in particular to television line diagram (TVL chart) plate of testing photoelectronic imaging system resolution power.
Background technology
In this day and age, photoelectronic imaging instruments such as digital camera, mobile phone cam, industry and medical endoscope have been widely applied among people's the life.The test of photoelectronic imaging instrument and Performance Detection have become very important in design with in producing.The utility model mainly need produce at this.The test chart that exists mainly is the film for 36mm now, and the traditional standard camera lens of 50mm is made.For present a feast for the eyes photo electric imaging system, some place can qualitative test, but can not quantitative test.The chart that has international detection resolving power now has: EIA 1956 resolution chart, ISO12233 Resolution chart, IEEE resolutionchart.The defective that they exist has:
(1) resolving power that can not the quantitative test electro-optical system.At first they have fixing size, for the numerical value of demarcating among the figure, can not represent constant meaning for different electro-optical systems.3 photo electric imaging systems are for example arranged, and the CMOS image sensor that is used for imaging is identical, the camera lens difference of use.For the position of demarcating 3 among the ISO12233 Chart figure, the line of the position of 1# optical system sign 3 is identical to width with the 300TVL line to width, should represent 300TVL; For the line of the position of 2# optical system sign 3 to the line of wide and 350TVL to wide identical, should represent 350TVL; The line of the position of 3# optical system sign 3 is identical to width with the 250TVL line to width, should represent 250TVL.We only go observation test with the Chart of ISO12233 so.We just do not know how many TVL 3 represent actually;
(2) can not satisfy the focusing needs.Every kind of optical system all will be considered focusing (according to working range, the focusing of finding a best from), and the best focusing of different optical systems is from being different.Chart for size is stipulated has relatively satisfied focusing from just not satisfying the full content of just seeing Chart; The full content of just seeing Chart have can not satisfy focusing from;
(3) special-purpose Chart cost height;
(4) can not represent the imaging situation of same visual field exactly.From the imaging of optical lens, the part of each imaging has meridian image field and arc to lose image field, shows to be horizontal line and vertical line on the Chart figure.Original Chart is separated by too far away at same part horizontal line and vertical line, can not know that the meridian image field in the same zone of expression and arc lose image field imaging situation;
(5) can not satisfy the more and more higher needs of pixel.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, and a kind of television line diagram plate of testing photoelectronic imaging system resolution power simple in structure is provided.
The purpose of this utility model can be achieved through the following technical solutions: the television line diagram plate of testing photoelectronic imaging system resolution power, it is characterized in that, this diagram board comprises that base plate, frame daughter board, line are to a bunch daughter board, information daughter board, described frame daughter board, line all are located at the base plate top to a bunch daughter board, information daughter board, and fixedly connected with base plate.
Described line is located in the middle of the frame daughter board a bunch daughter board, information daughter board.
Described line to a bunch daughter board comprise four regional visual field lines to bunch daughter board and center line to a bunch daughter board, wherein to be located at frame daughter board center respectively to bunch daughter board be the center of circle to four regional visual field lines, is that described center line is located at frame daughter board center to a bunch daughter board on the circumference and frame diagonal line intersection point of radius with the center to 0.7 double-length degree of the distance on four summits of frame.
It is right that described regional visual field line is provided with 2 groups of lines to a bunch daughter board, these 2 groups of lines are right to comprising large, medium and small each 3 son group line, and 2 groups of large, medium and small son group lines are provided with the back that is arranged in parallel is vertical, described large, medium and small son group line to according to from small to large order successively away from the frame daughter board.
Described 2 groups of large, medium and small son group lines are to being parallel to contiguous frame daughter board limit respectively.
It is right that described center line is provided with 2 groups of lines to a bunch daughter board, and these 2 groups of lines are right to comprising large, medium and small each 3 son group line, and 2 groups of large, medium and small son group lines are provided with the back that is arranged in parallel is vertical.
Also comprise the sign daughter board whether the test electron image rotates.
Described frame daughter board is a rectangular shaped rim.
Compared with prior art, advantage of the present utility model comprises:
(1) resolving power that can quantitative test optical system to be measured, we we can say that this optical system can reach the XXX tv line;
(2) versatility is good, tests and expresses with tv line, can both understand in the industry;
(3) do not exist because chart size and restriction focusing from, can be according to focus each parameter of distance calculation Chart of the best;
(4) with low cost, oneself designs, and can print width oneself according to the line of design, does not need commercial printing;
(5) more can know the imaging situation of expressing test zone, nearer because horizontal line and vertical line are separated by, can judge the noon image field of test zone and the imaging situation that arc loses image field;
(6) be not subjected to the restriction of pixel what and sharpness, existing chart fixes, and along with the increase of image pixel, resolution can be more and more higher, and the utility model forms according to the calculation of parameter of test macro, do not exist can not be not corresponding with test macro problem;
(7) Chart information is arranged, be fit to volume production more, avoided occurring Chart as far as possible and used and issue wrong situation.
