    Abstract: Two common-path interferometers share a measuring cavity for measuring opposite sides of opaque test parts. Interference patterns are formed between one side of the test parts and the reference surface of a first of the two interferometers, between the other side of the test parts and the reference surface of a second of the two interferometers, and between the first and second reference surfaces. The latter measurement between the reference surfaces of the two interferometers enables the measurements of the opposite sides of the test parts to be related to each other.

    Abstract: A mode-monitoring system used in connection with discrete beam frequency tunable laser provides optical feedback that can be used for adjusting the laser or for other processing associated with the use of the laser. For example, the output of a frequency tunable source for a frequency-shifting interferometer can be monitored to support the acquisition or processing of more accurate interference data. A first interferometer for taking desired measurements of optical path length differences traveled by different portions of a measuring beam can be linked to a second interferometer for taking measurements of the measuring beam itself. The additional interference data can be interpreted in accordance with the invention to provide measures of beam frequency and intensity.

    Abstract: A frequency tuning system for a laser includes mode-matched lasing and feedback cavities. A reflective facet of the feedback cavity is adjustable for retroreflecting different feedback frequencies to the lasing cavity without changing a fixed length of the feedback cavity. A selection among resonant frequencies of the feedback cavity provides for tuning the laser through discrete resonant frequencies of the lasing cavity.

    Abstract: Ein Frequenzschiebe-Interferometer wird angeordnet, um ein optisches Profil eines Testobjektes mit einer durchstimmbaren Lichtquelle zu messen. Eine Folge von Interferenzbildern des Testobjektes wird zusammen mit einem Messwert der Strahlfrequenzen erfasst, bei welchen die Interferenzbilder gebildet sind. Eine begrenzte Anzahl von erfassten Interferenzbildern des Testobjektes wird ausgewählt, so dass die überwachten Strahlfrequenzen mit einem vorher festgelegten Strahlfrequenz-Abstandsmuster ungefähr übereinstimmen. Eine weitere Bearbeitung folgt, basierend auf den ausgewählten Interferenzbildern.
