In the medical image interpreting apparatus having a pointing device for moving a cursor, medical image, interpretation report, and cursor are displayed on a display screen, and initial movement information and information on the destination of movement of the cursor are linked and stored, via the pointing device when the cursor begins to move, said initial movement information relevant to the initial movement is retrieved to obtain the linked information on the destination of movement and the cursor is moved to the destination of movement indicated in the obtained information on the destination of movement. Due to this, just by slightly moving the cursor, the cursor jumps to the desired destination of movement, therefore, it becomes possible to omit an operation of the pointing device in between. Due to this, the operation load of the pointing device is reduced, thus preventing an operator's thought in creating an interpretation report from being destructed, and the enhancement in interpreting efficiency and the reduction of interpretation mistakes are achieved.

A point diffraction interference measuring method comprises forming a substantially ideal spherical wave by using a point light source-generating unit 101, 102, allowing a light flux composed of the spherical wave to pass through a test sample 109, thereafter dividing the light flux into two light fluxes by using an optical path-dividing element 105, allowing one light flux of the divided light fluxes to pass through a pinhole 129 to covert the one light flux into a reference light beam which is a substantially ideal spherical wave, and detecting interference fringes generated by causing interference between the reference light beam and a measuring light beam which is the other light flux of the divided light fluxes. The wavefront aberration of the test sample can be measured by observing the interference fringes without being affected by the disturbance which would be otherwise caused by any system vibration or the like.

摘要:
Both the optical distance of the detected-light light path and the optical distance of the reference-light light path are simultaneously varied according to respective specified patterns, so that differences are created between the period of variation in the intensity of the required signal component (in the interference signals) and the periods of variation in the intensities of the coherent noise components. When the modulation scanning procedure is performed, the phase difference between the detected light and reference light in a specified state is determined as shape information for the above-mentioned detected surface on the basis of the interference signals output from the light-receiving element. As a result, it is possible to securely reduce the effects of coherent noise components generated as a result of the interference of specified noise light that has passed through at least portions of the detected-light light path and reference-light light path with the detected light or reference light.

A second harmonic generation (SHG) device is used for conversion of wavelength. The direction of polarization of light beams is suitably rotated by a direction-of-polarization rotating unit, for example by 45.degree., and thereafter these light beams are guided into the SHG device. This can minimize attenuation of intensity of light beam due to conversion of wavelength. Hence, using this direction-of-polarization rotating unit in the apparatus for measuring the medium, the intensity of light being incident upon the photodetector can be increased, whereby the refractive index of the medium can be measured more accurately than by the conventional apparatus.
摘要:
The present invention relates to an optical interference measuring apparatus and method for measuring displacement of an object. The apparatus and method reduces the displacement-measurement error caused by changes of the refractive index of the atmosphere or the like, in a measurement optical path and a reference optical path, by suppressing crosstalk caused by unfavorable mixing of reference light and measurement light with each other, thereby improving accuracy in the measurement. The apparatus produces interference between a measurement light beam and a reference light beam. The measurement light is propagated through a measurement optical path including a measurement reflector, which is at least movable along the measurement optical path. The reference light is propagated through a reference optical path including a reference reflector. The interference occurs in a predetermined interference system, whereby the displacement of the measurement reflector can be measured. The apparatus, especially, comprises a light path separating system for spatially separating from each other the optical path from the measurement reflector to the interference system, through which the measurement light is propagated, and the optical path from the reference reflector to the interference system, through which the reference light is propagated.
