  • OBLIQUE-ILLUMINATION SYSTEMS AND METHODS
    Publication number: 20130170024
    Abstract: Oblique-illumination systems integrated with fluorescence microscopes and methods of using oblique illumination in fluorescence microscopy are disclosed. An oblique-illumination system is attached to a fluorescence microscope objective. The oblique-illumination system can be used to illuminate from any desired direction the surface of an object located at a fixed known offset away from a sample solution containing fluorescently tagged targets. Oblique illumination is used to illuminate features of the surface while epi-illumination is used to create fluorescent light emitted from the tagged targets. The combination of oblique illumination of the surface and epi-illumination of the targets enables capture of images of the surface features and the fluorescent targets so that the locations of the targets in the sample can be determined based on the locations of the surface features.

  • Deconvolution for the reduction of blurring induced by internal reflections
    Patent number: 8478069
    Abstract: A system and method of image processing employ mathematical deconvolution to estimate the magnitude and location of a target object within an image. Both the nature of internal reflections and the convolution process by which each internal reflection contributes to blurring of the acquired image data may be measured and modeled. In accordance with mathematical deconvolution techniques, the combined effects of these internal reflections may be reduced to the extent that respective contributions of the target object and each individual reflection may be distinguished and quantified.

  • Stage driver for movable stages
    Patent number: 8467126
    Abstract: A manually operated driver for precision support stages having coarse and optional fine position control. A yoke connected to a movable stage slides along a shaft parallel to the direction of motion of the stage. The yoke has opposing pivot members that can, in one position, contact the shaft to self-lock the position of the yoke on the shaft and, in another position, remain clear of the shaft thereby allowing the yoke to slide freely on the shaft for coarse position control. The shaft has threads at one end that turn into a support block. Turning of the shaft with a knob and with the yoke locked to the shaft, slowly changes the position of the yoke and the connected stage for fine position adjustment of the stage. A pair of such drivers in orthogonal orientation on parallel x-y movable stages will provide two dimensional motion of stages.

  • Encoder interpolator with enhanced precision
    Patent number: 8384570
    Abstract: A method is presented for converting the sine/cosine signals from an optical encoder into a high-resolution position signal for use by a position control system while eliminating common noise and error sources. The improved noise performance resulting from the alias-free demodulation of encoder signals improves precision and reduces power consumption in precision motion control applications. The adaptive compensation of harmonic distortion eliminates errors related to offset, gain and quadrature of the encoder channels. The interpolator is able to process encoder signals at extremely high resolution without the speed limitation of prior art encoder interpolators.
