Optical paths from the positions of the measured spot images toward a light source are calculated, parameters of the test optical system when light rays from the positions of the spot images converge at the light source are specified, and a wavefront aberration of the test optical system corresponding to the parameters of the test optical system is calculated. | 05-22-2014 |
20150130922 | OBJECTIVE OPTICAL SYSTEM AND IMAGE ACQUISITION APPARATUS - The objective optical system includes a first optical system configured to collimate a divergent light flux from an object, a second optical system configured to converge the light flux from the first optical system, a beam splitter disposed between the first optical system and the second optical system, a reflector disposed on a side where the light flux from the second optical system is condensed and configured to reflect the light flux, and a third optical system configured to converge the light flux reflected by the reflector and then passing through the second optical system and the beam splitter. When a direction in which the light flux travels in the objective optical system is defined as an optical axis direction, positions of respective portions of the reflector in the optician axis direction are each changeable. | 05-14-2015 |

20120197908 | METHOD AND APPARATUS FOR ASSOCIATING A TABLE OF CONTENTS AND HEADINGS - Apparatus to associate a table of contents (TOC) and headings. An input section inputs TOC data C and body data D. A search section seeks the maximum value of a score function S which indicates the likelihood of associations M between a TOC and headings. An output section outputs associations M which maximize the score function S. The score function S is the total of a first sum obtained by summing unigram scores u for all the TOC items, where the unigram score u evaluates the likelihood of association of TOC item with a heading candidate line independently, and a second sum obtained by summing bigram scores b for all pairs of TOC items, where the bigram score b evaluates the likelihood of associations of paired TOC items with heading candidate lines on the basis of a degree of commonality. | 08-02-2012 |
