Publication number: 20020088919Abstract: According to the conventional light detection of a light probe microscope, there have been a problem that an excessive stray light is detected in case that a detector whose light-intercepting face is large with respect to the size of a bright point is used, and a problem that an optical axis alignment is necessary in case that the detector having a small light-intercepting face in the order of the bright point is used. Besides, in order to obtain plural optical information, plural light detectors have been necessary. It is adapted such that, by using a two-dimensional image sensor, a two-dimensional image is obtained in real time, and a signal intensity of an optional detection region in the two-dimensional image is obtained by picture signal processing means. It is adapted such that plural information are image-formed on the two-dimensional image sensor, and plural detection regions are designated.Type: ApplicationFiled: December 26, 2001Publication date: July 11, 2002Inventor: Hiroshi Muramatsu

Patent number: 6249000Abstract: A scanning probe microscope comprises a cantilever probe disposable proximate a surface of a sample and having a first resonance frequency. A three-dimensional fine movement element scans the cantilever probe and the surface of the sample relative to one another two-dimensionally. A sensor cantilever detects displacement of the cantilever probe during relative scanning movement between the cantilever probe and the surface of the sample. The sensor cantilever has a second resonance frequency different from the first resonance frequency and is disposed spaced apart but within touching distance from the cantilever probe so that displacement of the cantilever probe is transmitted to the sensor cantilever by contact between the sensor cantilever and the cantilever probe.Type: GrantFiled: August 3, 1998Date of Patent: June 19, 2001Assignee: Seiko Instruments Inc.Inventors: Hiroshi Muramatsu, Eisuke Tomita
