Title: Method for controlling autofocusing
Inventor: FUJITA HIROO
IPC: G01C3/06
Filed: 1989-03-31
Abstract: PURPOSE:To obtain the method to attain autofocusing with high accuracy by a simple constitution without requiring intricate adjustments by providing a reflected light masking part and detecting the light intensity of the region in the central part of the beam of the reflected light where the intensity is highest. CONSTITUTION:An object 4 to be measured is irradiated with laser light from a laser light source 1 via an objective lens 3 and the reflected light thereof is taken out as reflected light 112 by a beam splitter 108. The light intensity component in the central part of the beam is transmitted in the reflected light masking part 6 and the light intensity component of the other part is not transmitted. The peak intensity in the central part of the beam is particularly maximized in a best focus state when this light is received by a photodetector 7. The peak intensity decreases when an out-of-focus arises. The focus control direction is determined from the difference in the reflected light intensity before and after the 1st distance change of the objective lens 3 in the optical axis direction by the detected output of the photodetector 7 and the focus control is executed by detecting the state in which the difference in the reflected light intensity before and after the 2nd distance change of the objective lens 3 in the optical axis direction is zero.

Filed: 1986-04-09
Abstract: PURPOSE:To obtain a stable filter capable of sufficient attenuation by using an upper case of channel structure of a strip line filter so as to contact air tightly a lower case and the surrounding of a dielectric base arranged to the lower case. CONSTITUTION:An earth pattern 3 at the rear face of the dielectric base 1 is frought into contact with the lower case and fixed to the surrounding of the base 1. Half wavelength resonance electrodes 2a-2e are formed on the surface of the base 1 and the surrounding of the electrodes 2a-2e is cut off. The upper case 5 has a metallic wall 6 of channel structure and the lateral width is selected as the cut-off frequency in the waveguide mode being sufficient ly higher than pass band frequency of the strip line filter. A corner 7 of the channel structure is cut off partly so as to be fixed while the surrounding of the base 1 is retained. Thus, an undesired radio wave irradiation in space is decreased, and the filter with excellent attenuation and stable earthing of the base and less characteristic variation is obtained.
