Described herein is a light directing assembly for use in an object analysis system. The light directing assembly includes a plurality of optical relay assemblies. Each optical relay assembly includes at least one optical element configured to relay an interrogation beam from a light transmission system to an object and relay a return beam from the object to the light transmission system, the return beam being generated by reflection or back scattering of the interrogation beam by the object. Each optical relay assembly defines an interrogation angle at which the interrogation beam relayed by the optical relay assembly reaches the object, and an optical path length being the distance from the light transmission system to the object travelled by an interrogation beam via the optical relay assembly. The plurality of optical relay assemblies are further configured such that the optical path length for a given optical relay assembly has a predefined relationship with the optical path lengths of the other optical relay assemblies.

An optically realistic model eye is described. The optically realistic eye model has an optical axis and includes: an anterior replaceable module comprising a model cornea, model iris and model lens rotatably mounted for rotation about said axis, said module being representative of an emmetropic or pathological natural eye; an enclosure located posterior to said module and adapted to enclose a retinal area within which an image of an external object is brought to focus by said module; and a photoactive device movable within said enclosure and retinal area and adapted to detect or reflect a portion of the image for inspection, processing or analysis.

Physical model eye systems and methods

A contact lens having near vision and distance vision portions, the lens being movable on the eye between first and second positions, those positions corresponding with aligning the wearer's vision through the near vision and distance vision portions respectively. The lens is positionally stable on the eye in each of the two positions, and requires a force to be applied to the lens to move between the first and second positions. Preferably the lens has a back surface and a front surface, and said back surface has either one or two major back curve zones occupying a major portion of the lens back surface.
