    Abstract: Apparatus and methods are described for determining tomographic and/or topographic data relating to an object. The object is illuminated with at least one wave packet from light generated by a multi-spectral light source. The wave packet is split into two split wave packets, and an optical path difference (OPD) is introduced between the two split wave packets, that is smaller than the coherence length of the wave packet. The two split wave packets are combined to generate a 2D image of the illuminated object, and the data relating to the object is determined by processing the 2D image using long coherence phase shift interferometry algorithms, by analyzing the 2D image as if the 2D image was generated using monochromatic light having a wavelength that is equal to a mean wavelength of the wave packet. Other applications are also described.

    Abstract: In a system for analyzing optical properties of an object (350) a point source of light (100) composed of multiple spectral bands each having a respective amplitude, phase and polarization is converted by first optics (120, 150) into a line light source to illuminate an object line on the object. A beam splitter (200) splits the light exiting the first optics and directs a first portion of light on to the object (350) as an illuminated line and a second portion of the light on to a reference mirror (450). Second optics (500) collects respective first and second lines of light reflected by the object and mirror of and collinearly images the reflected lines of light as an image line on to an imaging spectrometer (550) wherein mutual interference allows determination of the optical properties of the object at each point along the object line.

    Abstract: A system (10) for measuring a physical characteristic of an object (11) using dual path, two-dimensional Optical Coherence Tomography (OCT) includes an extended broadband light source (13) producing an incident light beam (14) and an interferometer (15) having a beam splitter (16) that splits the incident beam into first and second component (17, 18) beams and directs the second component beam (18) on to a moveable mirror (19) for creating an optical path difference between the first component beam (17) and a reflection (20) of the second component beam. A focusing lens (21) having a focal plane (22) focuses the first component beam and the reflection of the second component beam to form a fringe pattern (23) on the focal plane, and a configurable imaging system (25) images the fringe pattern on to a plane (12) of the object to allow two-dimensional measurement of the object without spatial scanning.
