  • Depth of field extension for optical tomography
    Patent number: 7933010
    Abstract: An optical tomography system for viewing an object of interest includes a microcapillary tube viewing area for positioning the object of interest in an optical path including a detector. A motor is located to attach to and rotate a microcapillary tube. A device is arranged for transmitting broadband light having wavelengths between 550 nm and 620 nm into the microcapillary tube viewing area. A hyperchromatic lens is located to receive light transmitted through the microcapillary tube viewing area. A tube lens is located to focus light rays transmitted through the hyperchromatic lens, such that light rays from multiple object planes in the microcapillary tube viewing area simultaneously focus on the at least one detector.
