Laser-Bump Sensor Method And Apparatus

View page
US Patent:
59780916, Nov 2, 1999
Jun 26, 1998
Appl. No.:
Peter C. Jann - Santa Clara CA
Marco A. Krumbuegel - Danville CA
Reginald Lee - Alameda CA
Ming M. Yang - San Jose CA
HMT Technology Corporation - Fremont CA
International Classification:
G01B 1124
G01B 1130
G01N 2100
G01N 2188
US Classification:
An apparatus for measuring the height and diameter of laser-zone texture bumps on a rigid magnetic disk substrate is disclosed. The apparatus has a disk holder for supporting and rotating the substrate, and an optical beam-source assembly for directing a focused laser beam on the substrate, and for shifting the position of the beam's illumination spot on the substrate in a tracking (radial) direction. An optical detection assembly in the apparatus measures the deflection of the laser beam due to specular reflection of the beam by laser-zone texture bumps, as a function of time, in both scanning (circumferential) and tracking directions. A computational device in the apparatus functions to (i) calculate scanning and tracking deflection values which characterize beam deflections in the scanning and tracking directions, respectively, for a texture bump passing through the illumination spot produced by the beam on the substrate, (ii) select for bump-height analysis, those texture bumps whose scanning deflection values are above a selected threshold value and whose tracking deflection values are below a selected threshold value, indicative of a condition in which the selected textured bumps are each in focus and centered within said illumination spot, and (iii) determine the texture bump heights and diameters of the selected bumps from the beam deflections in the scanning direction. Also disclosed is a method by which the apparatus measures the light power which is scattered by the of laser-zone texture bumps on a rigid magnetic disk substrate.

Apparatus And Method For Optical Pulse Measurement

US Patent:
60088990, Dec 28, 1999
Jun 18, 1997
Appl. No.:
Rick P. Trebino - Livermore CA
Thomas Tsang - Brooklyn NY
David N. Fittinghoff - San Diego CA
John N. Sweetser - Livermore CA
Marco A. Krumbuegel - Danville CA
Sandia Corporation - Livermore CA
International Classification:
G01B 902
US Classification:
Practical third-order frequency-resolved optical grating (FROG) techniques for characterization of ultrashort optical pulses are disclosed. The techniques are particularly suited to the measurement of single and/or weak optical pulses having pulse durations in the picosecond and subpicosecond regime. The relative quantum inefficiency of third-order nonlinear optical effects is compensated for through i) use of phase-matched transient grating beam geometry to maximize interaction length, and ii) use of interface-enhanced third-harmonic generation.
