Abstract
The present invention is an apparatus and method for correcting errors generated by a laser with non-ideal tuning characteristics, the apparatus comprises a laser having non-ideal tuning characteristics. At least three interferometers are positioned in an operable relationship to the laser, wherein a sampling interferometer and at least one auxiliary interferometer correct for residual errors resulting from the laser; and wherein a measurement interferometer makes a measurement. A signal acquisition system is positioned in an operable relationship to each interferometer and a processor is positioned in an operable relationship to the signal acquisition system.
Claims14
An apparatus for correcting errors generated by a laser with non-ideal tuning characteristics, the apparatus comprising:
- a laser having non-ideal tuning characteristics;
- at least three interferometers positioned in an operable relationship to the laser, wherein a sampling interferometer and at least one auxiliary interferometer correct for residual errors resulting from the laser;
- and wherein a measurement interferometer makes a measurement;
- a signal acquisition system positioned in an operable relationship to each interferometer;
- and
- a processor positioned in an operable relationship to the signal acquisition system.
A method for correcting errors generated by a laser with non-ideal tuning characteristics, the method comprising the steps of:
- a) providing a laser having non-ideal tuning characteristics;
- b) positioning at least three interferometers in an operable relationship to the laser, wherein a sampling interferometer and at least one auxiliary interferometer correct for residual errors resulting from the laser, and wherein a measurement interferometer makes a measurement;
- c) positioning a signal acquisition system in an operable relationship to each interferometer;
- and
- d) positioning a processor in an operable relationship to the signal acquisition system.
