Abstract

The invention relates to optical arrangements which can be provided, preferably also in miniaturized form, for the most varied applications. They can be used in many sectors of life and also commercially, and indeed whenever information should be presented visually and/or optical information should be recognized and taken into account. It is the object of the invention to provide optical arrangements with which different optical information can be utilized in more complex form together in one arrangement. The optical arrangement in accordance with the invention is configured such that elements both emitting and detecting electromagnetic radiation are arranged on a common substrate or are configured thereat. A plurality of these elements are preferably present together in each case. It can, however, also be sufficient for specific applications to provide in each case an emitting or a detecting element with a plurality of the respective other elements.
