    Abstract: PURPOSE: An apparatus for measuring nanometric displacement and surface profile using a fiber-optic fizeau interferometer is provided to remarkably reduce time required for aligning optical axes because an optical element is not required. CONSTITUTION: An apparatus for measuring nanometric displacement and surface profile using a fiber-optic fizeau interferometer comprises a light source(10), a light source driver(70), a photo coupler(40), a lensed fiber(90), first and second photoelectric conversion units, and a computing unit(80). The light source emits light. The light source driver drives the light source. The photo coupler branches the light from the light source into two light routes and sends one and the other light routes to the first and second photoelectric conversion units, respectively. The lens fiber sends the light reflected from an object to the photo coupler. The first and second photoelectric conversion units convert the light from the photo coupler into an electric signal. The computing unit computes the nano displacement of the object by analyzing the electric signal.

    Abstract: PROBLEM TO BE SOLVED: To obtain highly precise interference wave information of high contrast, using one luminous energy ratio regulation means, in each of various specimens different in light return ratios.
    SOLUTION: This luminous energy ratio regulation filter 112 is arranged between a reference face and an inspected face of the interferometer. In the luminous energy ratio regulation filter 112, a luminous energy ratio regulation film 12 including a light reflecting and absorbing layer 12a and a dielectric reflection preventive layer 12b is provided on one face (face in a specimen 117 side) of a transparent substrate comprising glass, a light reflection preventive film 13 is provided on the other face (face in a reference face 116a side), one portion of incident light is reflected as to the incident light from a face opposed to the reference face, one portion of the residual light is absorbed to be emitted thereafter toward the specimen 117. In the regulation filter 112, one portion of return light is absorbed, reflection is restrained, and the residue is emitted toward a direction of the reference face 116a as inspected light, as to the return light from the specimen 117 incident from a specimen-opposed face side.

    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.
