    摘要: A method and apparatus are disclosed for measuring long bone density of small animals. A phosphor screen or plate is provided of a type that transduces incident ionizing radiation to emitted light. A small animal is positioned before the phosphor screen or plate and exposed to soft X-radiation having an energy level in the range of 11 to 16 Kev. Light emitted by the phosphor screen or plate is captured using a digital camera and a digital X-ray image is prepared of a long bone of the animal. The X-ray image is transformed into an X-ray density image and a region of interest is defined on the long bone in the X-ray density image. At least one row of pixels is scanned within the region of interest of the X-ray density image. A nonlinear least squares analysis of data obtained from the scanning step is conducted using a cylindrical model for the long bone within the region of interest.

    摘要: A tunable spectral filtration device is disclosed that includes one or more pairs of interference filters in series, wherein each element of each pair is independently selected from one or more options, independently positioned to intersect a path of converging or diverging light, and independently tilted with respect to the light path. Each filter may be either of a bandpass type, a shortpass type, a longpass type, a notch type, or multiple combinations thereof. Each filter in the series may be independently selected and tilted to tune the net spectral output of the series. The elements in a pair of filters may be tilted in opposite directions so as to cancel angle-of incidence dependent broadening of the spectral output of the individual filters for noncollimated light, as well as cancel translational shift of the transmitted light rays. The elements in a pair of filters may be tilted through orthogonal tilt axes so as to cancel polarization dependent broadening of the spectral output of the individual filters for light whose polarization state is a superposition of nonzero parallel and perpendicular components relative to the tilt axes.
