Abstract
The utility model belongs to the technical field of teaching instruments, especially to a demonstrator of the visual persistence phenomenon. The demonstrator comprises a pedestal (1), a power supply (2) and a switch (3) arranged on the pedestal (1), a motor (4) fixed on the pedestal (1), a vertical rod (5) fixed on the output shaft of the motor (4), four plate bodies (6) fixed on the periphery of the vertical rod (5), and a protruding arc (7) on the same side of each plate body (6). Each of the arcs (7) of the four plate bodies (6) is a quarter of a periodic image of a sinusoid. The demonstrator is simple in structure, easy for operation, and obvious in effect, allows student to directly observe the visual persistence effect, and enriches teaching contents.
Description
Technical field
The utility model belongs to technical field of teaching instruments, particularly a kind of persistence of vision phenomenon demonstrator.
Background technology
Television image reappears, and the image of fluorescent screen, iconoscope just constantly transmit one and another picture, and this picture one by one, because human vision persists the cause of phenomenon, seem that just as mobile continuously picture Here it is, and TV can be with the reason of action reproduction.And persistence of vision is exactly our eyes when seeing anything, all can produce a kind of very of short duration memory.These memories are write down, linked together, we will see that action produces, and picture is illusion continuously, persistence of vision that Here it is.In daily life, also have many phenomenons relevant with persistence of vision.For example: the daylight lamp that we use will extinguish 100 times p.s., and because human eye has the characteristic of persistence of vision, in the ordinary course of things, we discover flashing less than light.At present, in the teaching process of middle school physics, for more common persistence of vision phenomenon, adopt the preach method directly to impart knowledge to one's students usually, or for the example in a little real lifes, but the student understands or is more abstract.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of persistence of vision phenomenon demonstrator is provided, and this device can ocular demonstration persistence of vision phenomenon.
To achieve these goals, the technical solution of the utility model is as follows: a kind of persistence of vision phenomenon demonstrator, comprise base, base is provided with power supply and switch, motor is fixedly arranged on the base, and fixing montant on the output shaft of motor fixedly has 4 plate bodys around the montant, the same side of every plate body is provided with camber line, and the camber line of 4 plate bodys is followed successively by 1/4th of sinusoidal curve one-period image.
During demonstration, open switch, the motor rotation drives plate body and rotates, because the cause of persistence of vision, the observer can see a complete sinusoidal curve image.
As improvement, described camber line is convex.
The camber line of convex can make experimental phenomena more obvious.
As further improvement, described base is provided with framework, and framework surrounds 4 plate bodys, the front of framework and open top.
Extraneous image can influence observer's observation experiment phenomenon, and framework can be kept apart extraneous image, makes the easier observation of experimental phenomena.The framework open top has guaranteed illumination.
The utility model is simple in structure, operates easyly, and effect is obvious, makes the student observe visual persistence effect intuitively, has enriched the content of courses.
