  • Secure optical communication system utilizing deformable MEMS mirrors
    for voice communication, data retrieval from remote sensors and identification had been designed, built and tested. The system design allows operation at ranges of several hundred meters. The heart of the system is a modulated MEMS mirror that is electrostatically actuated and changes between a flat
  • Adaptive wavefront correction in two-photon microscopy using coherence-gated wavefront sensing
    a configuration (Fig. 1), based on the reciprocity theorem (18), where the returning light is reflected by the DM before entering the wavefront sensor and where a diffraction limited focus corresponds to a flat wavefront at the CGWS. This configuration leaves the final correction precision (but not the speed
  • Identification and Suppression of Thermal Reflections in Infrared Thermal Imaging
    . Right: Light microscope image of the surface of the brass plate. The consequence of this discussion: flat and polished surfaces, in particular all kinds of metal surfaces, may. easily result in reflections of IR radiation, even if they are not reflecting in the visible range. Therefore, all. analysis
  • Radar cross-section physics
    is proportional to 1/. On the right is a sphere, which also reflects back a signal proportional to the radius of the sphere (and not a function of wavelength). Orientation of the shape is critical. The worst case when the wave is incident perpendicular to a flat part of the surface, which results
  • Global Solar Technology - Smart packages for CPV cell devices
    used for. semiconductor solar cells can. in the photovoltaic (PV) conversion of. flat-plate (typically Silicon) photovoltaic. be manufactured by using. the solar energy. The conventional, single. systems, these solar cells utilise the light. semiconductor, solar cells only convert the. optoelectronic
  • Hollow Retroreflectors Promote Precision Optical Alignment
    mutually orthogonal front. surface mirrors bonded to form a. corner cube. In many cases, a device. will point at the light source such that. each individual mirror surface tilts at a. 55º angle of incidence to face it. devices could potentially replace flat. mirrors in almost any application
  • Glossary of Terms
    a glass furnace up to its operational temperature and then maintaining the temperature. Flat Glass. All types of glass (rolled, float, plate, etc.) produced in a flat form, regardless of the method of production. Float Glass. Float glass is a name for common window or plate glass. It is named float
  • Low Coherence Vibration Insensitive Fizeau Interferometer
    the. tilted beam Fizeau. 6 In this arrangement, a relatively large tilt angle is placed on the. reference flat giving a large angular offset between the test and reference beams. Prior to. incidence on the pixelated mask sensor, the two beams pass through a Wollaston prism,. producing two pairs
