ボルマトリクス

References and the source which I can inspect are not shown at all, or this article is insufficient. You add the source, and please cooperate with the reliability improvement of the article. (December, 2012)

A thing (clip) seeing is an image, and the object exists at the position of the Sekigan.

As for the image, the top and bottom is the same as an object, and the all around is reversed.

ボルマトリクス is the device which shows the object in the focus of one concave lens by letting you face each other to put relationships together, and locating two pieces of concave lenses as if there is it in the focus of the other concave lens.

Summary of the device

With the concave lens which lacks in the neighborhood of focus part in the upper part (had free = hole), I usually establish the complete concave lens in the bottom. The object in the bottom of the device seems to exist in the ceiling region of the device when I observe a device from the slant top that the light from an object is reflected by a concave lens of the top and bottom when I place an object in the focus part (equal to the bottom of the whole device) of the concave lens of the upper part and binds a real image together in the focus part (equal to the ceiling of the whole device) of the concave lens of the bottom.

 

I show a course of the light from an object with an arrow. The part which I showed with yellow is the range that can look at the image

•  

  A state judging from ① of the upper figure. The upper part: An image, bottom: Real object

•  

  A state judging from ② of the upper figure. It is an image that it seems that I stand out.

•  

  A state judging from ③ of the upper figure. If an angle to see becomes near horizontally, the upper part of the image is missing.

•  

  A state judging from ④ of the upper figure. Furthermore, seeing from a near position, I really know that nothing appears on the device horizontally.

Use

I am used for learning use of the concave lens in the school for the display at museums and am sold by the names such as ボルマトリクス, Mirage, the 3D magic scope.

A large thing is displayed with a title called "the famous clear water of the illusion" in Science Museum of Chiyoda-ku, Tokyo.

•  

  An object seems to loosen, but cannot touch it.

•  

  It is an image to be greatly seen on the top thinly, and the real thing is installed far below.

I can make it even if I use a mirror or a ladle covering up the source of light of the flashlight two pieces.
