摘要： A method for improving an OCT image of an object such as the retina of an eye, using optical coherence tomography by an imaging beam path. In order to suppress shadowing effects due to a surgical instrument moved in the imaging beam path, a time series of OCT images is produced. For an OCT image to be corrected, an area of the object lying in the image and shadowed by the instrument is determined. Another earlier OCT image in which the area of the object is not shadowed is searched in the time series. Image information for the area of the object is read from the earlier OCT image. A corrected OCT image is produced by inserting the read-image information into the OCT image to be corrected, wherein in the OCT image to be corrected, the image information replaces the area of the object which is shadowed by the instrument.

摘要： To provide a control device and control method capable of preventing overheating of both a master shaft and slave shaft. A control device for machine tools includes a master-shaft motor drive part, a slave-shaft motor drive part and a numerical control part that sends a master-shaft operation command to the master-shaft motor drive part, in which the master-shaft motor drive part drives the master-shaft motor based on the master-shaft operation command received from the numerical control part, the slave-shaft motor drive part drives the slave-shaft motor so as to synchronize with the master-shaft motor based on position feedback information received from the master-shaft motor, and the numerical control part creates the master-shaft operation command to change operation so as to restrict output of the master-shaft motor, upon the temperature of the master-shaft motor exceeding a first predetermined value, or the temperature of the slave-shaft motor exceeding a second predetermined value.
