    Abstract: An optics arrangement for a solid immersion lens (SIL) is disclosed. The arrangement enables the SIL to freely tilt. The arrangement includes a SIL having an optical axis extending from an engaging surface and a rear surface of the SIL; a SIL housing having a cavity configured to accept the SIL therein while allowing the SIL to freely tilt within the cavity, wherein the cavity includes a hole positioned such that the optical axis passes there-through, to thereby allow light collected by the SIL to propagate to an objective lens; and, a SIL retainer attached to the SIL housing and configured to prevent the SIL from exiting the cavity.

  • Patent number: 9950623
    Abstract: A vehicular projection system includes plural information collectors, a time-division multiplexing device and a projection mechanism. The plural information collectors are used for outputting driving information. The time-division multiplexing device includes plural wireless transmission modules. The time-division multiplexing device determines the transmitting sequence of plural information collectors according to the receiving sequence of wireless transmission requests from the plural information collectors. Moreover, the time-division multiplexing device determines the suitable wireless transmission modules according to the file properties of the driving information and the wireless transmission capabilities of the plural information collectors. Since the plural information collectors can simultaneously transmit driving information to the time-division multiplexing device through different wireless transmission modules, the wireless transmission efficiency is enhanced.

  • Patent number: 9678099
    Abstract: Techniques are disclosed for providing an optical assembly to provide stereoscopic images of a reflected laser spot to a camera for wind measurement. According to certain embodiments of the invention, an optical assembly can include left and right (or first and second) subassemblies having lens groups and reflective elements that cause light traveling left and right subassemblies to follow similar paths to focus on respective left and right portions of a camera. The camera can then use left and right images of reflected laser light to determine wind based on turbulence patterns in the left and right images.

  • Patent number: 9632291
    Abstract: There is provided an infrared optical system includes a light collecting lens having a curved light collecting surface for collecting infrared light incident from an object side, the lens being made of resin having a stepped shape being gradually deeper from periphery to center; and an optical path length correction element for correcting a difference in an optical path length produced by the stepped shape of the light collecting lens. The above-described stepped shape is provided to allow the lens to be thinner than the lens having the plano-convex shape. In other words, the infrared transmittance of the optical system is improved. In addition, the optical path length correction element can correct a difference in an optical path length produced by the stepped shape of the light collecting lens.
