Abstract
The invention discloses an image screen for lens imaging experiments. The image screen comprises a base, a vertical column, an image screen, a photoelectric sensor, a signal amplifying and measuring module and a display screen. The surface of the image screen is provided with a through hole in which the photoelectric sensor is embedded. The signal amplifying and measuring module is fixed on the back surface of the image screen. The display screen is fixed on the surface of the base. The photoelectric sensor, the signal amplifying and measuring module and the display screen are successively connected electrically. The image screen facilitates accurate determining for the position of the image and furthermore effectively improves measurement accuracy in optical experiments.
Description
Technical field
The present invention relates to a kind of Experiments of Optics apparatus, be specially a kind of lens imaging experiment as screen.
Background technology
The mensuration of the focal length of lens is basic Experiments of Optics, and this experiment usually builds lens imaging light path on optical bench, by measuring the data such as object distance, image distance, utilizes lens imaging formula, obtains the focal length of lens.But it was found that, owing to human eye is limited to the judgement of imaging definition, when moving in a certain little scope as screen, human eye is seen is all clearly as appearing to, thus the accurate location as screen is difficult to determine, thus brings measurement error.
Summary of the invention
It is an object of the invention to provide a kind of lens imaging experiment picture screen being conducive to improving Experiments of Optics measurement accuracy.
In order to solve above-mentioned technical problem, the present invention is achieved through the following technical solutions: a kind of lens imaging experiment, as screen, including base, vertical rod, is amplified and measurement module, display screen as screen, photoelectric sensor, signal；Described picture screen is plugged on base by vertical rod, has a through hole as screen surfaces, and photoelectric sensor is embedded in through hole, and its sensitive surface is in same plane with as screen；Signal amplifies and measurement module is fixed on as the screen back side, and display screen is fixed on susceptor surface；Photoelectric sensor, signal amplify and measurement module, display screen are electrically connected successively.
Described photoelectric sensor is photocell, or is silicon cell.
Due to the fact that the above-mentioned design of employing, following beneficial effect can be produced: experimentation coordinates eye observation, move about as screen in lens imaging position, photoelectric sensor is utilized to convert the optical signal of imaging to the signal of telecommunication, and export to display screen after signal amplification with measurement module, the position of picture can be accurately determined according to the size of data of display screen display.The present invention is conducive to accurately judging the position of picture, is effectively improved the accuracy that Experiments of Optics are measured.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the front schematic view of the present invention.
Fig. 2 is the side schematic view of the present invention.
In figure: 1. base, 2. vertical rod, 3. as screen, 31. through holes, 4. photoelectric sensor, 5. signal amplifies and measurement module, 6. display screen.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2, it is plugged on base 1 as screen 3 by vertical rod 2, has a through hole 31 as shielding 3 surfaces；Photoelectric sensor 4 is embedded in through hole 31 for the optical signal of imaging point converts to the signal of telecommunication, and the sensitive surface of photoelectric sensor 4 is in same plane with as screen 3.Signal amplification and measurement module 5 are fixed on the back side as screen 3 for amplifying the signal of telecommunication of photoelectric sensor 4 output and converting digital signal to, and display screen 6 is checked when being fixed on the surface conveniently experiment of base 1.Photoelectric sensor 4, signal amplify and measurement module 5, display screen 6 are electrically connected successively.Photoelectric sensor 4 is photocell or silicon cell.
