An optical minimum configuration of a laser interferometer for noncooperative scattering objects is investigated. An optimization of the SNR (signal-to-noise ratio) of the homodyne receiver is achieved by beam design. Scattering measurement object surfaces generate a speckle pattern on the detector surface which influences the SNR. Within the whole operating range of the optics, the transmitted light spot on the surface under investigation should therefore be small. The receiving optics should image the light spot onto the detector surface. The detection of a noncooperative object in a distance of 26 m is proven experimentally.

Using the concept of matrix theory for lens design, a triplet lens can be replaced by a singlet lens which has an equivalent system matrix without changing its optical performance. Then, using third order Siedel's first aberration coefficient of the singlet lens is equal to zero, and the focal length and the physical length of the triplet lens are kept constant as constraints, an algebraic technique for optimizing a triplet lens is derived. Results show that this new optimizing technique is more effective than other conventional techniques for optimizing a triplet lens in the case of plane waves.

Based on scale diffraction theory, binary phase gratings are designed and the effect of fabrication errors on the diffraction efficiency and uniformity is discussed. The theoretical and numerical analysis shows that (0, non-(pi) ) grating is more sensitive to phase delay error than (0, (pi) ) grating. Patterning error is very complex to analyze, but we can give a maximum intensity deviation to the grating.

We have proposed and discussed that an introduction of the Faraday medium to the optical bistable devices brings new and good characteristics on the application to optical sensing. In this paper, characteristics of the optical bistability are analyzed theoretically for the optical bistable operation with the Faraday effect, the threshold power, and several parameter dependences of the characteristic. Consequently, by controlling them with an external magnetic field which is an operatable factor, the optical bistability shows much usefulness and effectiveness by the following points: the controllability of the bistable operation, the reduction in the threshold power, and the enlargement in the discontinuous power variation ratio.

Electronic speckle pattern interferometry (ESPI) is a wholefield non-contact optical metrology technique for displacement measurement, based on the optical physics of surface-generated laser speckle. Since its inception during the early 1970s ESPI has gradually evolved into different opticaldesigns and has been applied to a range of engineering and non-engineering applications. Development of ESPI has continued during the 1990s with the introduction of new laser and optical technology into the interferometers, allowing further optimization and extending the potential applicability of the technique. This review considers the most notable developments of interferometer design and application that have occurred and been widely published during the 1990s, and examines the current and near-future direction of research into the technique.
