Description

A multi-mode observation periscope

technical field

The invention relates to a multi-mode observation periscope.

Background technique

A periscope refers to a device that protrudes from the sea surface to the sea surface or from a low-lying tunnel to spy on activities on the sea surface or on the ground. The main functions of traditional periscopes include observing ships on the water surface, observing aircraft in the air, estimating the distance of the attacked target, providing its azimuth and distance to the fire control system, implementing landmark navigation or celestial navigation in the submerged state, etc. The basic principle of the periscope structure is shown in Figure 1, including a Z-shaped lens barrel 1 and reflectors 2 and 3 in the lens barrel 1. The reflectors 2 and 3 are placed at the two corners of the Z-shape, and the two ends of the lens barrel 1 are set. There are openings 5,6. The traditional periscope has a simple structure and low production cost, but it is only suitable for one person to operate and observe, and cannot realize simultaneous observation by multiple people.

Modern periscope manufacturers have developed a series of new-generation photoelectric periscopes using the latest achievements in photoelectric technologies such as low-light night vision, infrared thermal imaging, laser ranging, computers, automatic control, and stealth. The periscope system has a fairly good observation effect under daylight and night conditions. It can effectively monitor the sea surface and sea air, collect navigation data, search and identify various sea targets, and the observed images can be recorded for playback. However, this type of periscope has complex technology, large volume, complicated driving mechanism, large rotation volume and high price.

Detailed ways

The key of the invention is to realize multiple light paths by using one beam splitter. The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

Refer to Figure 9 for the basic system structure of the embodiment of the present invention. In order to ensure light transmission, the set angle is generally 45 degrees:

(1) Embodiment At the Z-shaped two right-angle turns a and b of the lens barrel 1, one side is designed with reflectors 2 and 3 at 45 degrees to the axis of the lens barrel 1, respectively. The inner wall of the lens barrel 1 is preferably painted black to avoid the reflection of light in the barrel from affecting the imaging clarity. When setting, ensure that the mirror surfaces of the two reflecting mirrors 2 and 3 are parallel to each other, and the centers of the two reflecting mirrors 2 and 3 are on the axis of the lens barrel 1 . Under the lens barrel 1 (that is, close to the reflector 3), design a beam splitter 4 parallel to the reflector 2 to split the light into two; set an opening at the position of the beam splitter 4 and perpendicular to the axis of the lens barrel 1 7. It can be set in the form of a branch lens barrel. In order to realize front and rear azimuth observation, openable and closable light baffles 8 and 9 can be designed at the openings 6 and 7 .

(2) In order to correct the inverted image, the embodiment provides an accessory 10 . Attachment 10 includes right-angle lens barrel 13, and the diameter of the right-angle lens barrel is based on the opening that can be nested. A reflective surface 12 is designed at the right angle of the lens barrel. The reflective surface 12 forms an angle of 45 degrees with the axis of the right-angle lens barrel 13.

(3) In order to provide far-sighted observation, the embodiment also provides a telescope 11 that can be used at the window.
