Deskrizzjoni
English: Knives, forks, and spoons made from a biodegradable starch-polyester material.

The photo has been realized using the photoelasticity method, an experimental method which gets a fairly accurate picture of stress distribution even around abrupt discontinuities in a material.

When a ray of plane polarised light is passed through a photoelastic material, it gets resolved along the two principal stress directions and each of these components experiences different refractive indices. The difference in the refractive indices leads to a relative phase retardation between the two component waves.

The setup used to photograph this photo was probably composed of:

  • A regular light source, with a quarter-wave plate installed to polarize the emerging light
  • A regular photo camera, with a quarter-wave plate installed in front of the lens

Light and camera being installed and oriented in the same direction, the two

quarter-wave plates were turned with the polarizing axis in the same direction.
Français : Couteaux, fourchettes et cuillères biodégradables en polyester à base d'amidon.
Português: Facas, garfos e colheres fabricadas com um material poliéster biodegradável à base de amido. A foto foi tirada usando o método fotoelástico, um método experimental que fornece uma imagem bastante precisa da distribuição do stress mesmo que o material possua descontinuidades abruptas.
Tiếng Việt: Dao, nĩa, muỗng được làm từ một loại vật liệu bột sợi tổng hợp có khả năng phân huỷ sinh học.
