  • Alignment of optical components
    Patent number: 4428644
    Abstract: A means for aligning components of an optical system without the use of conventional optical equipment is disclosed. This means includes the use of a pair of electrodes in proximity with the light guiding portion of a pyroelectric system element. The absorption of light in the waveguide produces a current in the pyroelectric material tht is monitored at the electrodes. Alignment of the system components is achieved by adjusting their relative position to increase the monitored signal.
    Type: Grant
    Filed: September 21, 1981
    Date of Patent: January 31, 1984
    Assignee: Bell Telephone Laboratories, Incorporated
