  • Method for controlling the frequency dependence of insertion loss in an optical assembly
    Patent number: 7027678
    Abstract: A method for controlling the frequency dependence of insertion loss in an etalon-lens-fiber (ELF) optical assembly comprises defining target frequencies and insertion loss objectives therefor and adjusting the optical path length between pairs of the etalon, lens and fiber components until insertion loss objectives are achieved. Insertion loss objectives include insertion loss and insertion loss ripple objectives. The method allows for control of the frequency dependence of insertion loss and insertion loss ripple without introducing additional components, such as spectral filters, into the system.

  • Acousto-micro-optic deflector
    Patent number: 6751009
    Abstract: An acousto-micro-optic deflector (AMOD) is provided. This device uses a special combination of an acousto-optic deflector (AOD) and a micro-optic deflector (MOD) to provide agile gimballess beam steering over large angles. The combination is driven such that the entire field of regard of the device is accessible, and continuous contact with the target point is maintained.

  • Uniform sensitivity light curtain
    Patent number: 5539198
    Abstract: A light curtain having linearly arranged pairs of light transmitting and receiving which may be placed on opposing sides of a zone to be protected. The light curtain provides uniform sensitivity across the region to be protected as the light transmitters emit a light beam which begins as an omnidirectional point source which is truncated and refocused by an optical lense. Predetermined portions of the beam are blocked to assure uniform intensity across the width of the transmitter.
