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 relative to the sample. Simultaneously and synchronously, charge is shifted in a parallel direction Y' within the CCD, so that data from a given point in the sample continues to accumulate, hi 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.

The present invention relates to digital pathology, and relates in particular to a digital pathology scanner illumination unit. In order to provide digital pathology scanning with improved illumination, a digital pathology scanner illumination unit (10) is provided that comprises a light source (12), a light mixing chamber (14), and a light diffuser (16). The light source comprises a plurality of light elements (18) that are arranged longitudinally along a linear extension direction. The mixing chamber comprises a transparent volume (22) providing a mixing distance (DM) between the plurality of the light elements and the light diffuser such that light with a uniform intensity is provided at a downstream edge (26) of the mixing chamber; and the mixing chamber is arranged, in terms of light propagation, between the plurality of the light elements and the light diffuser. Further, the light diffuser comprises a diffusing material such that the light is transformed into light that has uniformity at different angles, in particular low angles.
Abstract:
The present invention relates to DNA sequencing with reagent cycling on the wiregrid. The sequencing approach suggested with which allows to use a single fluid with no washing steps. Based on strong optical confinement and of excitation light and of cleavage light, the sequencing reaction can be read-out without washing the surface. Stepwise sequencing is achieved by using nucleotides with optically cleavable blocking moietys. After read-out the built in nucleotide is deblocked by cleavage light through the same substrate. This ensures that only bound nucleotides will be unblocked.

Detection mechanism provided over entrance of the processing section includes shell and camera with laser which emits beam on the surface of the glass in the gap between sliding rollers. Focal plane of the camera corresponds to the beam irradiation surface, and signal output terminal of the camera is connected with the control system in such a way that when glass passes the detection area, laser irradiates the glass surface and the line structured laser is modulated based on the glass to form laser modulation image with distribution of light and shade, staggered movement direction, or distorted laser lines. The camera transmits the captured glass information and parameters to the control system.

Abstract:
In the scanning molecule counting method which detects light of a light-emitting particle in a sample solution using a confocal or multiphoton microscope, there is provided an optical analysis technique enabling the scanning in a sample solution with moving a light detection region in a broader area or along a longer route while making the possibility of detecting the same light-emitting particle as different particles as low as possible and remaining the size or shape of the light detection region unchanged as far as possible. In the inventive optical analysis technique, there are performed detecting light from the light detection region and generating time series light intensity data during moving the position of the light detection region along the second route whose position is moved along the first route in a sample solution, and thereby, the signal indicating light from each light-emitting particle existing in a predetermined route is individually detected using the time series light intensity data.
