Abstract: A system and method of non-contact measurement of the dopant content of semiconductor material by reflecting infrared (IR) radiation off of the material into an integrating sphere to scatter the received radiation and passing portions of the radiation through band pass filters of differing wavelength ranges, comparing the level of energy passed through each filter and calculating the dopant content by referencing a correlation curve made up of known wafer dopant content for that system.

Abstract: A method can include emitting, from a light source, directional light through fuel contained in a fuel tank, and determining a refraction angle of the directional light after the directional light passes through an interface with the fuel. The method can further include determining, by a processing device, an index of refraction of the fuel based on the determined refraction angle, and determining, by the processing device, a density of the fuel based on the determined index of refraction of the fuel.

Abstract: Materials and objects tagged with wavelength selective particles such as SERS nanotags modified for wavelength selectivity. As used herein, a wavelength selective particle is one which cannot be effectively excited or interrogated at one or more wavelengths where a reporter molecule associated with the particle would normally produce a spectrum. Also disclosed are methods of manufacturing wavelength selective particles and methods of tagging materials or objects with wavelength selective particles.

Abstract: Scatterometry measurement systems, illumination configurations and respective methods are provided, which comprise illumination beams that have vertical projections on a target plane comprising both a parallel component and a perpendicular component, with respect to a target measurement direction. The illumination beams propagate at an angle to the plane defined by the measurement direction and a normal to the targets surface and generate diffraction images which are off-center at the imaging pupil plane. The eccentric diffraction images are spatially arranged to avoid overlaps and to correspond to measurement requirements such as spot sizes, number of required diffraction orders and so forth. The illumination beams may be implemented using illumination pupil masks, which provide a simple way to increase scatterometry measurements throughput.

Abstract: Provided is an image-forming optical system comprising: a plurality of image-forming lenses that form a final image and at least one intermediate image; a first phase modulator that is disposed further on an object side than any one of the intermediate images formed by the image-forming lenses is and that applies a spatial disturbance to a wavefront of light coming from the object; a second phase modulator that is disposed at a position at which at least one of the intermediate images is flanked by the first phase modulator and the second phase modulator, and that cancels out the spatial disturbance applied, by the first phase modulator, to the wavefront of the light coming from the object; and an adjusting part for adjusting an optical magnification in an image-forming relationship between the first and second phase modulators is included.

Abstract: The invention relates to a method for the Raman spectroscopic, in ovo sex determination of fertilised and hatched birds' eggs (1), wherein the embryo, including the extra-embryonic structures, can move in the egg, and is not yet attached to the shell at the time of measuring. In addition, the following steps are carried out: monitoring the time course of the hatched egg until forming at least one recognisable blood vessel (21); creating a hole (2) in the shell in the region near to the attached bloody vessel, using a hole-generating unit; finding the blood vessel forming in the egg, using a vision system (19, 13) and a coaxial or lateral illumination with light (10a) in the visible wavelength range; positioning at least one blood vessel in the laser focus of a laser source (3), either by moving the egg or moving a lens (6) of a device (5) for introducing the laser light (3a), and detecting the Raman scattered radiation (7); registering the Raman scattered radiation of the irradiated blood vessel using the device for introducing the laser light, and for detecting the Raman scattered radiation, wherein, during the measuring process, a movement of the blood vessel out of the focus can be avoided by tracking using the vision system; evaluating the Raman scattered radiation in an evaluation unit; determining and displaying the sex of the embryo in the bird's egg.

Abstract: A polarimeter for measuring chirality of a material comprising an optical ring cavity comprising a plurality of reflective elements configured to promote bi-directional propagation of a laser beam within the cavity, a laser-emitting device configured to introduce a first input laser beam and a second input laser beam into the ring cavity, and a Faraday rotator and a phase compensator configured to suppress a birefringent background as the first and second laser beams pass through the ring cavity, wherein the plurality of mirrors, Faraday rotator, and phase compensator are configured such that light from the first and second laser beams passes through a chiral material located within the cavity a sufficient number of times for a measurement of optical rotary dispersion (ORD) and circular dichroism (CD) of light transmitted through the chiral material to be obtained. Particular implementations include monolithic ring cavities or microresonators or use of intra-cavity gain media.
