“…Due to the BiMiD crosstalk the projection (OLED microdisplay) and detection (photo diode matrix) field has to be separated. In Grossmann et al 13 a paraxial lens design and system simulation (fringe projection and recalculation of the 3-D object) based on the classical system setup applying the BiMiD is presented. Based on this system simulations, display characterization (see chapter 2) and system application parameters adapted optical lens designs were simulated.…”

Small and compact optical system designs are needed in nearly all application scenarios of optical projection and imaging systems, e.g. automotive, metrology, medical or multimedia. Most active optical systems are based on separated imaging (e.g. camera unit) and image generating units (e.g. projection unit). This fact limits the geometrical miniaturization of the system. We present compact optical system designs using the new technology of bi-directional sensor devices. These devices combine light emitting and light detecting elements on one single chip. The application of such innovative opto-electronic devices -so-called bi-directional OLED microdisplays (BiMiDs) -offer a huge potential for miniaturization with a simultaneous increase of performance due to a new integration step. For these new bi-directional sensor devices new optical design concepts for simultaneous and sequential emission and detection are necessary. Because the simultaneous emission and detection can disturb the functionality of the optical system. New concepts has to be applied. A first concept is an exemplary 3-D metrology system applying fringe projection. A second concept is a pico-projection system with an integrated camera function. For both concepts the system configurations and the optical design are discussed. Due to the application of the bi-directional sensor device ultra-compact systems are presented.
