    Abstract: Image projection devices, high-speed fiber scanned displays and related methods for projecting an image onto a surface and interfacing with the projected image are provided. A method for projecting one or more images and obtaining feedback with an optical input-output assembly is provided. The input-output assembly comprising a light-scanning optical fiber and a sensor. The method includes generating a sequence of light in response to one or more image representations and a scan pattern of the optical fiber, articulating the optical fiber in the scan pattern, projecting the sequence of light from the articulated optical fiber, and generating a feedback signal with the sensor in response to reflections of the sequence of light.

  • Publication number: 20050134687
    Abstract: Systems and methods for producing circular extinction (CE) contrast images of anisotropic samples. Microscope systems for determining circular extinction (CE), the differential transmission of left and right circularly polarized light resulting from circular dichroism (CD) of an anisotropic sample, include mechanically driven optical components and an image detector such as a monochromatic CCD camera to detect light intensities. In one aspect, optical components include a tunable filter, a rotatable linear polarizer and a variable retarder. The tunable filter is adjustable to provide light at a specific desired wavelength. The linear polarizer is adjustable to provide linearly polarized light with a specific wave vector, and the variable retarder is adjustable to produce near perfect circular polarized light at every selected wavelength.
