摘要： A method and apparatus is provided for scanning an object, featuring scanning an incident beam in a substantially curved scan pattern; and moving an object at a predetermined rate along an axis substantially orthogonal to a plane of the curved scan pattern so that a two dimensional image can be formed by successive passes of a circularly scanned spot. In particular, a laser beam scans around an objective lens at a fixed radius RL with a fixed input angle θd. When scanned in this manner, the laser beam before the objective lens forms a “cone” of directions (so herein it is referred to as a “conical scan”). Scanning in this fashion produces the curved scan pattern at the object (substrate). By moving the object (substrate) at the predetermined rate along the axis orthogonal to the plane of the curved scan pattern, the two dimensional image can be formed by successive passes of the circularly scanned spot.

摘要： A method and corresponding apparatus for determining the centroid (Vc) of a waveform signal being sampled at a set of parameter values (Vi, i=1, . . . , n) yielding a corresponding set of sampled amplitudes (Ai, i=1, . . . , n), each parameter value and corresponding amplitude forming a sampled point (Vi, Ai), the method including the steps of: selecting an amplitude at which to create an interpolated point; interpolating a first parameter value corresponding to the amplitude selected in the step of selecting an amplitude; and performing a centroid calculation using only the sampled points with an amplitude greater than a predetermined threshold. The waveform is sometimes sampled in the presence of background noise, and the method sometimes also includes: estimating the background (Bi) for each value in the set of parameter values at which sampling is performed; and reducing the amplitude (Ai) of each sampled amplitude by the background (Bi) so estimated.

摘要： An optical beam generator system for use in an imaging system that forms an image in a substrate comprises a beam generator, a mode filter and a state selector. The optical beam has a first power level above an exposure level that exposes the image in the substrate and a second power level below the exposure level which does not expose the substrate. The beam generator generates a near single mode coherent optical beam in response to received command signals corresponding to an "on" state and generates a multimode incoherent optical beam in response to received command signals corresponding to an "off" state. The filter is optically coupled to the beam generator and attenuates an optical component of the received optical beam which is not single mode to a magnitude below the exposure level. The state selector generates the "on" and "off" command signals corresponding to the "on" and "off" states such that the filter outputs the coherent optical beam with minimal attenuation during the "on" state and with maximum attenuation during the "off" state.

摘要： An optical spectrum analyzer (OSA) 10 sequentially or selectively samples (or filters) a spectral band(s) 11 of light from a broadband optical input signal 12 and measures predetermined optical parameters of the optical signal (e.g., spectral profile) of the input light 12. The OSA 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates or spreads spatially the collimated input light, and reflects the dispersed light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the light back through the collimating lens 18. The lens 18 focuses spectral bands of light (λ1–λN) at different focal points in space. One of the spectral bands 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each spectral band 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.

摘要： A fiber Bragg grating reference module provides a precise temperature reference for a temperature probe, including a thermistor, located in close proximity thereto, and includes an optical fiber having a fiber Bragg grating therein, a glass element and a reference housing. The fiber Bragg grating has two ends and with a coefficient of thermal expansion. The glass element anchors the two ends of the fiber Bragg grating, and has a substantially similar coefficient of thermal expansion as the coefficient of thermal expansion of the fiber Bragg grating to ensure that the glass element does not substantially induce strain on the fiber Bragg grating as the ambient temperature changes. The reference housing has a cavity and also has a means for receiving and affixing one end of the fiber Bragg grating and for suspending the fiber Bragg grating in the cavity leaving the other end of the fiber Bragg grating free to move as the ambient temperature changes without inducing strain in the fiber Bragg grating. The glass element includes a glass tube collapsed over the entire length of the fiber Bragg grating. Alternatively, the glass element includes a glass tube locally collapsed at the two ends of the fiber Bragg grating over a part of length of the fiber Bragg grating.
