Abstract
Techniques specifically developed for the design and manufacturing of specialized holographic optical elements (HOEs) that are used in the fabrication of integrated optical systems for laser- Doppler velocimetry (LDV) applications are presented. The specialized HOEs needed for the construction of an integrated LDV-optics are: beam-splitters, lenses and/or lens arrays, phase correction plates and the corresponding waveguide structures. The HOEs are designed by means of computer programs that facilitate the optimization of the recording geometry and provide information for the correction procedures needed for optimized performance. The HOEs are recorded in dichromated gelatin films and are subsequently subjected to chemical and thermal after-treatment. These procedures guarantee the realization of HOEs with high diffraction efficiency and low scattering losses. The optimized holographic process has been previously described. In this report we discuss the following specialized HOEs and their specific characteristics as required by the LDV applications.
