Patent number: 7193205Abstract: A processing apparatus calculates and applies calibrations to sensors that produce quasi-sinusoidal, quadrature signals, using fixed or programmable electronic circuits, a circuit to calculate the phase and magnitude corresponding to the two input (quadrature) signals, and a circuit for accumulating the number of cycles of the input signals. The apparatus also includes a circuit to generate Gain, Offset, and Phase calibration coefficients by comparing a phase space position of a measured phasor with the position of an idealized phasor whose locus in phase space is a circle of predetermined radius with no offset. The calculation of the coefficients occurs without user intervention, according to a pre-programmed rule or rules.Type: GrantFiled: April 23, 2006Date of Patent: March 20, 2007Assignee: GSI Group CorporationInventors: Paul Remillard, Stuart Schechter, Douglas A.

Patent number: 7002137Abstract: The disclosed optical encoder includes a scale and a sensor head. The scale includes an optical grating and an optical element. The sensor head includes a light source, a detector array, and an index detector all of which are disposed on a substrate. The scale is disposed opposite the sensor head and is disposed for movement relative to the sensor head. The distance between the scale and the sensor head is selected so that the detector array lies near a talbot imaging plane. The light source emits a diverging beam of light, which is directed towards the scale. Light from the diverging beam of light is diffracted by the grating towards the detector array. Light from the diverging beam of light is diffracted by the optical element towards the index detector. The detector array provides a measurement of the position of the sensor head relative to the scale. The index detector provides a reference measurement of the position of the sensor head relative to the scale.Type: GrantFiled: August 13, 2002Date of Patent: February 21, 2006Assignee: GSI Lumonics CorporationInventors: William G. Thorburn, Norman J. Tobey, Melvin J. J. Teare, Douglas A. Klingbeil, Ralph A. Kelliher
