    Abstract: A imaging method is described that includes: obtaining a spectral weighting function indicative of an attribute of the reference sample; illuminating a target sample with light whose spectral flux distribution corresponds to the spectral weighting function to produce a corresponding target image, wherein the target image is indicative of a response of the target sample to the corresponding illumination at multiple spatial locations of the target sample; and identifying one or more target features in the target sample based on the target image.

    Abstract: An optical channel monitor is provided that sequentially or selectively filters an optical channel(s) 11 of light from a (WDM) optical input signal 12 and senses predetermined parameters of the each filtered optical signal (e.g., channel power, channel presence, signal-noise-ratio). The OCM 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 spatially each of the optical channels 11 of the collimated light, and reflects the separated channels of light onto the mirror 22. A null/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the null/4 plate 26 to the diffraction grating 20, which reflects the channels of light back through the collimating lens 18. The lens 18 focuses each separated channel of light (null1-nullN) at a different focal point in space. One of the optical channels 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 optical channel 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.

    Abstract: The invention relates to a spectrometer (10) with a dispersive element (16) that can be displaced between at least two positions. In the first position, the simply dispersed radiation (44) of a selected wavelength is reflected directly back in the incident beam path (42), while in the second position the dispersed radiation (32) of the selected wavelength can be directed to a reflective element (30) that is positioned such that the radiation (34) can be directed at least one more time across the dispersive element (16) and then back to the incident beam path (38). The spectrometer is provided with a device, for example, a mirror, an echelle grating or a prism that deflects the beam from the plane of dispersion, which is arranged in such a manner that the simply simply dispersed beam (34) runs in another plane than the multiply dispersed beam (36). The mirror (30) is inclined by an axis (54) that extends parallel to the plane of dispersion and perpendicular to the incident beam (32).

    Abstract: A small-spot imaging, spectrometry instrument for measuring properties of a sample has a polarization-scrambling element, such as a Lyot depolarizer, incorporated between the polarization-introducing components of the system, such as the beamsplitter, and the microscope objective of the system. The Lyot depolarizer varies polarization with wavelength. Sinusoidal perturbation in the resulting measured spectrum can be removed by data processing techniques or, if the depolarizer is thick or highly birefringent, may be narrower than the wavelength resolution of the instrument.
