28、O 14880 is to clarify the terms used in the field of microlens arrays.Microoptics and microlens arrays are found in many modern optical devices.1They are used as coupling optics for detector arrays, the digital camera being an example of a mass market application. They are used to enhance the optica

29、l performance of liquid crystal displays to couple arrays of light sources and to direct illumination for example in 2D and 3D television, mobile phone and portable computer displays. Microlens arrays are used in wavefront sensors for optical metrology and astronomy, lightfield sensors for threedime

30、nsional photography and microscopy and in optical parallel processor elements.Multiple arrays of microlenses can be assembled to form optical systems such as optical condensers, controlled diffusers and superlenses.23Furthermore, arrays of microoptical elements such as micro-prisms and micro-mirrors

31、 are used.45The expanded market in microlens arrays has generated a need to agree on basic terms and definitions for microlens arrays and systems and this part of ISO 14880 aims to satisfy that need.

32、lens arrays Part 1: Vocabulary and general properties1 ScopeThis part of ISO 14880 defines terms for microlens arrays. It applies to microlens arrays which consist of arrays of very small lenses formed inside or on one or more surfaces of a common substrate and systems. The aim of this part of ISO 1

33、4880 is to improve the compatibility and interchangeability of lens arrays from different suppliers and to enhance the development of technology using microlens arrays.2 Terms and definitions2.1 Basic definition of microlens and microlens array2.1.1microlenslens in an array with an aperture of less

34、than a few millimetres including lenses which work by refraction at the surface, refraction in the bulk of the substrate, diffraction or a combination of theseNote 1 to entry: The microlens can have a variety of aperture shapes: circular, hexagonal or rectangular for example. The surface of the lens

35、 can be flat, convex or concave.2.1.2microlens arrayregular arrangement of microlenses on a single substrateNote 1 to entry: Irregular or structured arrays are sometimes used, for example, in beam shaping, diffusion, and homogenization.2.2 General terms and definitions2.2.1effective front focal leng
