Latest Patents

One of his latest patents is a spectroscopic apparatus with a dispersive device designed for collecting sample data in synchronism with the relative movement of a focus. In this Raman spectroscopy apparatus, exciting light is focused on a sample as a line focus. Spectra from points in the line focus are dispersed in rows on a CCD detector, which has a two-dimensional array of pixels. The line focus moves longitudinally in a direction relative to the sample, while charge is shifted in a parallel direction within the CCD. This innovative approach ensures that data from each sample point arises from illumination integrated along the line focus, facilitating the stitching of data to form an image of the sample. Additionally, 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.

Another significant patent is for a spectroscopic probe that includes a monolithic block of transparent material and GRIN lenses. Light for illuminating a sample is delivered by an optical fiber, while light scattered by the sample is output by another optical fiber. The block features opposing angled faces coated with a dichroic filter coating and a reflective coating, respectively. A method for making these blocks is also disclosed, where the coatings are first applied to a large sheet, and blocks are then cut from the sheet using angled cuts. This design reduces the number of components required, allowing for miniaturization of the probe, making it suitable for use in endoscopes.
