An apparatus for inhibiting melatonin synthesis in a horse comprises a blinker having an internal surface of which at least a part is diffusing. A source of light is positioned for direction into the horse's eye by the diffusing-surface. The light source and diffusing surface are configured such that the light directed into the horse's eye is blue.

Apparatus and method for inhibiting melatonin synthesis in a horse

A method for wavelength-selective mixing and/or distribution of polychromatic light. When mixing polychromatic light, lights having only one wavelength are successively fed to each member of a selective chain to form a partial spectrum, and when distributing chromatic light, one wavelength is filtered out of each member and the remaining spectrum is fed after reflection to the next member for being further decomposed. A chain of photonic crystals is used both for mixing and distributing and a wavelength-selective coupler/decoupler is associated to each crystal. Fields of application include the wavelength-selective mixture or distribution of polychromatic light and spectrometric measurements and environment monitoring.

To form an optical element ( ), in particular an interferometric sensor, an optical fiber ( ) is placed tangent to a cylindrical supporting element ( ); a straight portion ( ) of the optical fiber and the supporting element are surface fused; and a cavity ( ) is formed in the optical fiber ( ), the cavity being defined by facing surfaces ( ) of the straight portion ( ) substantially perpendicular to the axis of the straight portion ( ). The optical fiber ( ) and supporting element ( ) may be subjected to traction during surface fusion, to form a small cross-section portion close to the cavity, and which, when light is conducted by the optical element, provides for reducing the amount of light dispersed in the cavity.

Method of producing an optical fibre resonant cavity, in particular for an interferometric sensor, and optical fibre resonant cavity produced thereby

A luminous intensity sensor element having a flat disk-shaped element ( ) made of material with a high thermal expansion coefficient and of low thermal conductivity, and in turn having, on opposite faces ( ), an optically absorbent layer ( ) and a reflecting layer ( ). On receiving excitation radiation (R), the optically absorbent layer ( ) is heated and transmits heat to the flat disk-shaped ( ), which in turn is heated internally in spatially nonuniform manner and is deformed together with the superimposed reflecting layer ( ). The reflecting layer ( ) receives an incident reference layer beam (S) to generate a reflected light beam having optical characteristics (&Dgr;&phgr;) depending on the aforementioned deformation (&Dgr;d) and varying in response to the excitation radiation.
