  • Laser sheet generator
    Publication number: 20060033935
    Abstract: A laser line generator having a laser diode, or other laser source, emits a laser which is passed through an aspherical lens to create a two-dimensional fan-shaped light sheet. This light sheet is reflected off a flat mirror to expand the width of the light sheet without increasing the size required by the optical path. The light sheet is then reflected by parabolic mirror to create a straight, planar light sheet.

  • High speed laser micrometer
    Patent number: 6947152
    Abstract: A large profile, high speed laser micrometer is formed from a light source unit comprised of a plurality of emitter modules that combine to emit a laser sheet and a detector array comprised of a plurality of detector modules. The laser micrometer also includes a data processing unit. Each of the emitter modules is aligned with a corresponding detector module such that an object passing between the light source unit and the detector array can be measured to an accuracy of at least 4/100ths of an inch.
