  • Publication number: 20110242541
    Abstract: The shape of a prism is set such that an excitation light beam that enters the prism to cause surface plasmon resonance to be generated is not irradiated onto the corners of the prism after being totally reflected within the prism. The angle of a surface that the excitation light exits the prism is set to an angle at which the excitation light beam is not totally reflected. Thereby, the excitation light beam returning to a light source, and being scattered within the prism are prevented, and therefore the accuracy of measurements can be improved.

    Abstract: A light guiding device is operable to receive incident light emitted by a light source through a capture surface. The received light exits the light guiding device through an exit surface provided adjacent to and aligned with an aperture of light receiver. In this manner, light from the light source can be inserted into the receiver where it may be combined with additional incident light captured by the receiver. The light source might be a projector and the light projected may correspond to operational data relating to the operation of the receiver or images corresponding to data captured by a further receiver device operating with a different form of sensor or in a different region of the spectrum. In order to improve the composite image observed by a user of the light receiving device, the operation of the light source can be controlled to vary the intensity of the light emitted. In one example, this variation can be in response to the ambient light level, as sensed by a suitable sensor.

    Abstract: Disclosed is an optical component, which comprises a prism element adjacent to a lens element, where the two elements are separated by a small air gap. In disclosed embodiments, the elements have adjacent and parallel surfaces which are substantially planar and which, with the small air gap, operate through Total Internal Reflection (“TIR”) to direct light beams that strike the planar surfaces. Light beams that strike at less than the critical angle are internally reflected, while light beams which strike at greater than the critical angle pass through. The TIR surfaces thereby separate the desired optical signals from the spurious ones. The combined TIR prism lens operates as a single and integrated component which directs desired light beams to a reflective optical processing element such as a Spatial Light Modulator and which focuses the processed light beams as they leave the combined TIR prism lens.

  • Patent number: 7515345
    Abstract: A high-performance image-forming optical objective lens made compact and thin, particularly in the object side direction, by twice folding the optical path by means of two prism lenses longitudinally separated and arranged in an angular relationship to one another. The prisms have entrance and exit faces each of which is constructed of a curved surface having optical power, as well as having a rotationally symmetric polynomial aspheric attribute. The image-forming optical objective is particularly suited to helmet-mounted applications wherein the angular means for folding the optical path provides for an optical objective configuration that closely conforms to the exterior surface contour of the helmet, while providing a minimal forward projection in object space from the helmet.

  • Patent number: 7515194
    Abstract: An image pickup optical system includes, in order from the object side, a front unit having at least one reflecting surface with power that is rotationally asymmetrical, an aperture stop, and a rear unit having at least one reflecting surface with power that is rotationally asymmetrical. In this case, F-numbers in two directions perpendicular to each other on a plane perpendicular to the optical axis are different. Decentration takes place in one of the two directions and the F-number in a direction perpendicular to a decentering direction is smaller than that in the decentering direction. When the F-number in the decentering direction is represented by FNY and the F-number in the direction perpendicular to the decentering direction is represented by FNX, the optical system satisfies the following condition: 1.1<FNY/FNX<2.0.
