Abstract: Embodiments of a system and method for collecting hyperspectral and polarimetric data that are spatially and temporally coincident include a dispersive element configured to receive incident electromagnetic radiation. The dispersive element is configured to disperse a non-zero order of the electromagnetic radiation into its constituent spectra, which is directed to a first focal plane array, and may be read out as hyperspectral data. The dispersive element is also configured to reflect a zero order of the electromagnetic radiation, which is directed through a polarity discriminating element to a second focal plane array, which may be read out as polarimetric data. By synchronously reading out the first and second focal plane arrays, the hyperspectral and polarimetric data may be both spatially and temporally coincident.

Abstract: In a Raman spectroscopy apparatus, exciting light is focussed on a sample (26) as a line focus 38. Spectra from points in the line focus are dispersed in rows 46 on a CCD detector 34, having a two-dimensional array of pixels. The line focus moves longitudinally in a direction Y (arrow 48) relative to the sample. Simultaneously and synchronously, charge is shifted in a parallel direction Y′ (arrow 50) within the CCD, so that data from a given point in the sample continues to accumulate. This ensures that the data from each sample point arises from illumination which is integrated along the line focus, and makes it easier to stitch the data together subsequently to form an image of the sample. In order to provide averaging in the X direction during fast, low resolution scanning, the line focus is swept across the sample in a zig-zag fashion, between boundary lines 60.

Abstract: A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a linear sensor by moving while attaching the linear sensor to the adjustment surface. The linear sensor is supported by the side wall of the housing while abutting on the adjustment surface and receives a light beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the linear sensor passes.

Abstract: An encoder/sensor can obtain sensing results from objects in an encoding/sensing region; a trigger detector can respond to objects in a trigger detection region, providing respective trigger signals; and a relative motion component can cause relative motion of objects into the trigger detection region, from it into the encoding/sensing region, and within the encoding/sensing region. In response to an object's trigger signal, control circuitry can cause the encoder/sensor and/or the relative motion component to operate so that the encoder/sensor obtains sensing results indicating a time-varying waveform and processing circuitry can obtain data from the sensing results indicating a time-varying waveform. The time-varying waveform can include information resulting from the relative motion within the encoding/sensing region. The encoder/sensor and trigger detector can be implemented, for example, with discrete components or as sets of cells in a photosensing array on an integrated circuit.

Abstract: The apparatus and methods herein provide quantitatively controllable light sources and expanded dynamic range endoscopy systems that can improve the quality of images and the ability of users to distinguish desired features when viewing tissues by providing methods and apparatus that improve the dynamic range of images from endoscopes, in particular for example with endoscopes that have dynamic range limited because of small image sensors and small pixel electron well capacity, and other optical system constraints. The apparatus and methods herein, for example, combine light sources with quantitatively variable spectral output and quantitatively variable wavelength dependent intensity distribution with image sensors and controllers to create an expanded dynamic range endoscopy system. By digitally combining illumination data from the digitally controllable light source with the digital image data from the image sensor the system synthesizes expanded dynamic range images whose dynamic range exceeds the dynamic range of the image sensor alone thus providing greatly enhanced information content in the acquired images.

Abstract: A time delay integration (TDI) sensor (22) comprises a sequence of cells (42, 44, 42, 44) numbered 1 to N. The TDI sensor is configured for transferring a charge from the cell numbered 1 via the cells numbered 2 to N-1 to the cell numbered N. Each cell (42; 44) in the sequence of cells is either sensitive or insensitive in the sense that when the TDI sensor (22) is evenly illuminated by light (46) incident on any of the insensitive cells (44) is at most 90% of the intensity of the light (46) incident on any of the sensitive cells (42). The sequence of cells (42, 44, 42, 44) comprises, in this order: a first sensitive cell (42), at least one insensitive cell (44), and a second sensitive cell (42). An imaging system comprising a TDI sensor and a method of imaging an object are also disclosed.

Abstract: A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.

Abstract: In a spectroscopy module 1, a light passing hole 50 through which a light L1 advancing to a spectroscopic portion 4 passes is formed in a light detecting element 5. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is bonded to a front plane 2a of a substrate 2 with an optical resin adhesive 63. Thus, it is possible to reduce a stress generated onto the light detecting element 5 due to a thermal expansion difference between the light detecting element 5 and the substrate 2. Additionally, on the light detecting element 5, a first convex portion 101 is formed so as to be located at least between the light detecting portion 5a and the light passing hole 50 when viewed from a direction substantially perpendicular to the front plane 2a. Thus, when the light detecting element 5 is attached to the substrate 2 via the optical resin adhesive 63, the optical resin adhesive 63 is dammed at the first convex portion 101. Thus, the optical resin adhesive 63 is prevented from penetrating into the light passing hole 50.

Abstract: In a spectrographic workpiece metrology system having an optical viewing window, the viewing window is calibrated against a reference sample of a known absolute reflectance spectrum to produce a normalized reflectance spectrum of the reference sample, which is combined with the absolute reflectance spectrum to produce a correction factor. Successive production workpieces are measured through the window and calibrated against the viewing window reflectance, and transformed to absolute reflectance spectra using the same correction factor without having to re-load the reference sample.
