Embodiment 1

[0042] This embodiment provides a virtual periscope, such as figure 1 and figure 2As shown, it includes: a lens 1, adapted to be installed underwater, for receiving light from an object on the water, and imaging the object on the water on a photosensitive element 2; a photosensitive element 2, used to convert the image signal into The electrical signal is input to the display element 3; the display element 3 is used to convert the electrical signal into an image output; it also includes an optical filter 4, which is arranged between the lens 1 and the photosensitive element 2 for Filter and remove the interfering light that passes through the lens 1 but does not reflect the morphological information of the target on the water; wherein, the interfering light is scattered light that is refracted from the air and enters the water through the sea surface and is scattered by seawater molecules.

[0043] In the virtual periscope of the present embodiment, an optical filter 4 is ad...

Embodiment 2

[0056] This embodiment provides a virtual periscope, which is an improvement on the basis of Embodiment 1, the difference is that: Figure 4 As shown, the optical filter 4 is a polarizer, and the polarization direction of any point on it is parallel to the direction of the line connecting the point to the center. Such a polarizer can filter and remove interfering light to the greatest extent, which is better for improving the imaging contrast and improving the imaging quality of the virtual periscope.

Embodiment 3

[0058] This embodiment provides a method for producing a virtual periscope as described in Embodiment 1 or 2, including the step of disposing the optical filter 4 between the lens 1 and the photosensitive element 2 . The filter element 4 is the polarizer in embodiment 1 or 2. The virtual periscope produced by the production method of the invention can eliminate interfering light and has the advantage of improving imaging contrast.

Abstract

The invention provides a virtual periscope and a production method and an application thereof. The virtual periscope comprises a lens, which is suitable of being arranged underwater and is used for receiving light rays from a waterborne target object and enabling the waterborne target object to be imaged on a photosensitive element; the photosensitive element, which is used for converting the image signal into an electrical signal, and inputting the electrical signal to a display element; the display element, which is used for converting the electrical signal into an image and outputting the image; and a light filtering member, which is arranged between the lens and the photosensitive element, and is used for filtering out interference rays which pass through the lens but do not reflect shape information of the waterborne target object, wherein the interference rays are scattered rays generated when the light rays refracted by sea surface from the air into water are scattered by seawater molecules. The virtual periscope adopts the light filtering member to filter out the interference rays, so that interference can be reduced or eliminated, imaging contrast is improved, and imaging quality of the virtual periscope is improved.

Description

technical field [0001] The invention relates to the technical field of observation equipment, in particular to a virtual periscope for observing objects on water from underwater and a production method and application thereof. Background technique [0002] The virtual periscope is the main equipment for underwater carrier platforms (such as submarines, UUVs, AUVs, ROVs, diving equipment, etc.) to observe water and air targets. The virtual periscope is used underwater, and it generally includes a lens, a photosensitive element and a display element. After being refracted by the water, the light emitted by the target on the water passes through the lens, forms an image on the photosensitive element, and outputs it through the display element, so that it can be used by people in the water. Observe the target on the water. However, in practical applications, the definition of the virtual periscope in the prior art is poor, and those skilled in the art have conducted many techni...
