  • Patent number: 5502567
    Abstract: A micropolarimeter comprises an analyzer (1) and a detector (3), which is typically a photodetector array. The detector has a circular configuration of a number N of sectors. Analyzer (1) and detector (3) form a unit with the analyzer assigning different polarization values to the sectors. Analyzer and the detector contain no moving parts. Three different embodiments are proposed for the analyzer: a glass cone, covered with a polarizing thin film stack, a metal grid polarizing array, and an array of polarizing waveguides. The micropolarimeter (14) is used preferably in a microellipsometer system which can serve as a tool for film diagnostics, especially optical characterization of thin films.

  • Patent number: 5465611
    Abstract: A sensor head (1) is described, which has a spacer (5b) between a carrier element (2) and the spring arm (7), which, perhaps carries a sensor tip (9) at the free end; the spacer defines the distance d between the spring arm (7) and the carrier element (2). In a preferred embodiment, the spacer (5b) comprises a sacrificial layer (5a), which is etched out, except for the spacer (5b), after the formation of a corresponding layer system between the spring arm (7) and the carrier element (2). The carrier element (2) and the spring arm (7) are each provided with a reflecting layer (4 and 6). In accordance with another specific embodiment, plasmonactive layers can also be provided.

  • Patent number: 5134949
    Abstract: A ship of the 50 ton class includes a deep-V hull shape which is a partially monohedron fully planing hull with a hand chine and two bottom risers, a water jet propulsion system cooperating with a motor, and control apparatus for controlling the motor and propulsion system. Preferably, the motor is a 16 cylinder marine diesel engine having a maximum speed of between about 1800 and 2100 rpm and a maximum power of about 1900 kW, while the water jet is a high speed, high rpm water jet having a maximum water jet speed of between about 1400 and 1600 rpm, the water jet coupled to the motor by means of a reduction gear between about 1:1.15 and 1:1.
