摘要： The ellipsometer (1) and method involve directing polarized light for interaction with an optical system (2) under study at different angles of incidence from a single beam of light and detecting the light interacted with the optical system by reflection and/or transmission for each of a plurality of different angles of incidence. The simultaneous illumination of the optical system under study at a whole range of angles of incidence alpha from a single beam of light and the collection a large multiplicity of data from the different angles detected can be accomplished rapidly and easily and with accuracy without scanning and with only one ellipsometer. A lens (7) is used to focus the incoming light to provide the range of different angles of incidence alpha . The range of angles is at least one or two degrees and preferably thirty degrees or more. A second lens (8) refocuses the interacted light to a linear, multi-element detector array (6) which extends in the plane of the incidence. Each of the detector elements (9) detects a narrow range of angles of incidence within the relatively wider range of angles of incidence of the illuminating beam. If the incident illuminating rays are polychromatic and a wavelength dispersing element (10) acts on the reflected rays each detector element of a square array (11) detects a narrow range of wavelengths and angles of incidence.

摘要： The measurement arrangement for analysing electromagnetic radiation contains, in the radiation path, the following assemblies arranged one behind the other: (a) at least one linear polariser (2); (b) at least one optically active element (3) with a known optical activity, i.e. with a known frequency dependence of the rotation of the polarisation plane; and (c) at least one analyser (4), whose polarisation direction has a fixed pre-set orientation in relation to the emission direction of the linear polariser. The beam emerging from the analyser (4) is conveyed across a photosensitive sensor (7, 8) of a measurement circuit. The overall intensity of the radiation to be measured is determined by creating a reference signal in various ways, namely by direct measurement with an optically active element partly removed from the radiation path, by the decoupling of a partial beam or by a beam splitting analyser. The measurement arrangement enables a very rapid analysis (up to calibration time measurement) of electromagnetic beam with an extremely high resolution power, without any moving mechanical parts being necessary. The fields of application of the mesurement arrangement are the determination of the optical focus of the radiation, the determination of the special characteristic of the radiation and also spectrometric and/or photometric testing of specimens.

摘要： Apparatus and method for determining dynamically the polarization vector direction, or polarization vector components and associated temporal phase angle, of a light beam. The apparatus includes a compact polarization beam splitter (19) that receives a beam of light (17), separates the beam into two perpendicular polarization components (21, 23) and directs these components to a pair of optical detectors (25, 27) and associated circuits (29) that form the sum and difference signals of the electrical signals produced by the optical detectors. This produces a projection of the polarization vector on a given direction. If the light is generally elliptically polarized, use of two such polarization beam splitters (49, 59) and four optical detector (55, 57, 65, 67) allows reconstruction of the polarization ellipse for the light beam. Alternatively, use of one such polarization beam splitter (219), two optical detectors (225, 227) and a rotating wave plate (231) in a multiplexed configuration (233) allows reconstruction of the polarization ellipse. The polarization detector is very compact and may be housed in a container that is no more than a few cm. in diameter.

摘要： A photopolarimeter for the simultaneous measurement of all four Stokes parameters of light. The light beam, the state of polarization of which is to be determined, strikes, at oblique angles of incidence, three photodetector surfaces (D0, D1, D2) in succession, each of which is partially specularly reflecting and each of which generates an electrical signal proportional to the fraction of the radiation it absorbs. A fourth photodetector (D3) is totally light absorbing and detects the remainder of the light. The four outputs thus developed form a 4x1 signal vector I(Boolean not) which is linearly related, I(Boolean not)=A(Boolean not) S(Boolean not), to the input Stokes vector S(Boolean not). Consequently, S(Boolean not) is obtained by S(Boolean not)=A(Boolean not)-1 I(Boolean not). The 4x4 instrument matrix A(Boolean not) must be nonsingular, whichrequires that the planes of incidence of each of the light beams are all different. For a given arrangement of four detectors, A(Boolean not) can be either computed or determinated by calibration.
