Abstract: A detection optical unit (112) of an optical apparatus is configured to produce an imaged representation (151, 152) of a sample object (150) on a detector (114). An adjustable filter element (119) is arranged in a beam path of the detection optical unit (112) that defines the imaged representation (151, 152). A controller is configured to drive the adjustable filter element (119) to filter the spectrum of the beam path with a first filter pattern (301-308) and with a second filter pattern (301-308) and to drive the detector (114) to capture a first image, associated with the first filter pattern (301-308), and to capture a second image, which is associated with the second filter pattern (301-308). The controller is furthermore configured to determine a focus position (181) of the sample object (150) based on the first image and the second image. The first filter element (301-308) here defines a first line and the second filter element (301-308) defines a second line.

Abstract: A digital camera includes a focusing-control-unit that calculates a defocus amount using detection signals of phase difference detection pixels and drives a focus lens according to the defocus amount, and a movement-detection-unit that detects whether a movement is present in a captured subject-image. The focusing-control-unit calculates the defocus amount according to an auto-focus instruction, and drives, in a case where the defocus amount exceeds a threshold-value, the focus lens according to the defocus amount and then performs the phase difference AF again to complete auto-focusing. Further, in a case where the defocus amount is equal to or smaller than the threshold-value, the focusing control unit performs the phase difference AF only once to complete the auto-focusing. Further, in a case where a movement is present in the subject-image, the focusing-control-unit sets the threshold to a larger value than in a case where a movement is not present in the subject-image.

Abstract: Provided is an optical measuring device capable of easily improving accuracy in measurement of a measurement object. Light is projected from a light projecting unit into a measurement space. Light passing through the measurement space is directed toward a first image sensor through a first optical system, and directed toward a second image sensor through a second optical system. Within the measurement space, a position of a first focus of the first optical system and a position of a second focus of the second optical system in an X direction are different from each other. Whether the measurement object is positioned at the first focus, on a side of the first focus closer to the light projecting unit, or on a side of the first focus away from the light projecting unit is determined based on the signals outputted from the first and the second image sensor.

Abstract: To store information in a ferroelectric material, a sample probe is used to bring about mechanical action on individual domains and thereby to cause a reversal of polarization in the individual domains, with electrodes situated below the ferroelectric material being able to have a bias applied to them to stabilize the change/reversal of polarization. The reversal of polarization causes an alteration in the surface topography of the ferroelectric material, and this alteration can be used to read the information. The stored information is therefore obtained by ascertaining the surface topography of the ferroelectric material. The information is written and read using an AFM tip, with the tip being able to be operated in contact or tapping mode for the purpose of writing, and additionally in noncontact mode for the purpose of reading.

Abstract: A device and a method for focus detection that increases the amount of light projected on an object to capture the object without fail. Light rays are projected onto an object by a projection optical system using a projection pattern film that contains transparent and non-transparent parts, or semi-transparent parts with different light transmission rates. A pair of light rays from the object pass through the shooting lens and are guided onto a photo-electric converter by a focus detection optical system to compose a pair of object images. The focus adjustment state of the shooting lens is detected based on the image defocus amount of the pair of the object images.
