Abstract: A data acquisition apparatus includes an illumination device, a first beam splitter, a measurement unit, and a photodetector. A measurement optical path and a reference optical path are positioned between the illumination device and the photodetector. In the first beam splitter, light traveling in a first direction and light traveling in a second direction are generated from incident light. The measurement optical path is positioned in the first direction, the reference optical path is positioned in the second direction, and the measurement unit is disposed on the measurement optical path. In the optical surface of the first beam splitter, an incident position of light emitted from the illumination device changes with time, and the angle formed by light propagating through the measurement optical path and the optical axis of the measurement optical path changes with change in the incident position.

Abstract: A sample observation apparatus includes a light source unit, an illumination optical system, a detection optical system, a light detection element, and an image processing apparatus. The scanning unit relatively moves the light spot and the sample. An optical member is disposed. The illumination optical system and the detection optical system are disposed such that an image of a pupil of the illumination optical system is formed at a pupil position of the detection optical system. The image of the pupil of the illumination optical system is decentered relative to a pupil of the detection optical system due to refraction caused by the sample. The illumination optical system, the detection optical system, and the optical member are configured such that quantity of light passing through the pupil of the detection optical system changes by decentering.

Abstract: A sample shape measuring apparatus includes a light source unit, an illumination optical system, a detection optical system, a light detection element, and a processing apparatus. A scanning unit relatively moves a light spot and the sample. Illumination light applied to the sample is transmitted through the sample, and light transmitted through the sample is incident on the detection optical system. The light detection element receives light. The illumination optical system or the detection optical system includes an optical member. The processing apparatus obtains a quantity of light based on a received light, calculates at least one of a difference and a ratio between the quantity of light and a reference quantity of light, calculates an amount of tilt at a surface of the sample, and calculates a shape of the sample from the amount of tilt.
