Definitions
- the invention relates to the field of portholes for ships, submarines or any aquatic equipment such as an oil platform having an outer face submerged and an inner face to the air having a field of vision allowing the observation of elements. close to the structure (ship hull, wall of submerged equipment).
- this invention applies to the observation of the propellers of a ship, below the water level, and of the hydraulic flows near the propellers, from inside the structure.
- the windows are flat panes with parallel faces, laminated or not, made of mineral glass and / or of polymer material.
- the minimum viewing angle that can be achieved is limited to 49 ° around the normal to the glazing.
- the accessible solid angle is then only 2.14 sr, ie 34% of the solid angle usually accessible through glazing. We cannot therefore look directly at the hull, wall ... To observe, for example, the hydraulic flows from upstream to downstream of a propeller, it is necessary to multiply the portholes with different positions.
- the object of the invention is to provide a window of an immersed structure to see, from the inside of the structure in the air, outside the structure in the water, at the edge of the structure, so as to considerably reduce the constraints of positioning the window over the entire surface of the structure, and to reduce the number of windows itself, when it is desired to observe in different directions.

- the angles of the various interior flat sections relative to the exterior face of the window are different from each other.
- Geometric optics allow these angles to be defined as a function of the position of the window and of the area to be observed.
- a camera can be positioned inside the boat, facing each of the facets to observe a specific part of the external environment of the structure: hull or other wall, propeller, etc.
