The full width array spectrophotometer system includes one or more substantially linear elongated illumination arrays of closely spaced multiple illumination sources. The sources include sets of illumination sources, including a first set of different color illumination sources and a second set including one or more UV-emitting illumination sources. The sets are arranged to span a printer paper path or other object path to illuminate a band extending transversely across a printed print media sheet or other object moving in the path. A full width array light imaging sensor includes an elongated array of multiple closely spaced photodetectors for detecting plural colors and is positioned adjacent to and extending substantially parallel to the linear array(s) to receive radiation reflected from the transverse illuminated band.

Abstract: A hyperspectral imaging system and methods thereof especially useful in fields such as medicine, food safety, chemical sensing, and agriculture, for example. In one embodiment, the hyperspectral imaging module contains a light source (1) for illuminating the object (6) in a light-tight housing (17). The light is spectrally filtered (4) prior to illuminating the object. The light leaving the object is then directed through imaging optics (T) to an imaging array (9). In another embodiment, the object of interest is illuminated by ambient light which is then compensated by a light modulation system. In this embodiment, the light emitted from the object is spectrally filtered prior to reaching the imaging array.

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 pool 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 pooled to remain at the first pool portion 101. Thus, the optical resin adhesive 63 is prevented from penetrating into the light passing hole 50.

Abstract: A compact wavelength dispersing device and a wavelength selective optical switch based on the wavelength dispersing device is described. The wavelength dispersing device has a folding mirror that folds the optical path at least three times. A focal length of a focusing coupler of the device is reduced and the NA is increased, while the increased optical aberrations are mitigated by using an optional coma-compensating wedge. A double-pass arrangement for a transmission diffraction grating allows further focal length and overall size reduction due to increased angular dispersion.

Abstract: A spectrometer apparatus includes a refractor element, a slit, a detector, a diffraction grating, and a corrector lens. The refractor element includes a rear surface and a front surface. The slit provides an optical path to the rear surface of the refractor element, and is configured to transmit an image incident thereupon along the optical path. The detector is positioned facing the rear surface of the refractor element. The diffraction grating faces the front surface of the refractor element, and is configured to spectrally disperse and reimage the image of the slit toward the front surface of the refractor element. The corrector lens is positioned between the refractor element and the diffraction grating such that the image is provided to the detector corrected for a spherical aberration caused by a separation distance between the detector and the rear surface of the refractor element.

Abstract: Obtaining spectral images of an eye includes taking an optical system that images eye tissue onto a digital sensor array and optically fitting a multi-spectral filter array and the digital sensor array, wherein the multi-spectral filter array is disposed between the digital sensor array and an optics portion of the optical system. The resulting system facilitates acquisition of a snap-shot image of the eye tissue with the digital sensor array. The snap shot images support estimation of blood oxygen saturation in a retinal tissue. The resulting system can be based on a non-mydriatic fundus camera designed to obtain the retinal images without administration of pupil dilation drops.
