A three-dimension scanning apparatus and method of use is disclosed. The scanner includes a first camera and a processor. The first camera has an adjustable focus distance and is placed at a first distance from a first object to obtain an image of the first object. The processor adjust the focus distance of the first camera to a first focus distance that forms an image of the first object at an image plane of the first camera. Additionally, the apparatus includes a light intensity meter for measuring a level of light intensity at the first camera. The first camera includes an adjustable aperture. The processor adjusts the aperture of the first camera automatically based on the measured light level.

An imaging apparatus includes: an imager that performs imaging of a subject through an imaging optical system including a focus lens capable of changing a position of a principal point in a range between a first position and a second position in a direction of an optical axis; and an imaging controller that continuously performs plural imaging control operations for causing the imager to perform imaging of the subject through the imaging optical system in a state where the principal point of the focus lens is set at each of plural imaging positions which are set in a movement range as at least a partial range of the range, and the imaging controller makes distances between the plural imaging positions narrower and sets a larger number of the plural imaging positions in an imaging control operation performed later in time series among the plural imaging control operations.

A high-contrast liquid crystal light control device provides angle independent variable transmission of incident light for uniform gray shades. The liquid crystal light control device comprises a combination of first and second liquid crystal devices arranged in optical series and positioned between optical polarizers. The director field of the second liquid crystal device is a mirror image of the director field of the first liquid crystal device, and the first and second liquid crystal devices are placed together so that the azimuthal directions of the surface-contacting directors are in parallel alignment at the adjoining or confronting surfaces of the substrates of the first and second liquid crystal devices. The liquid crystal light control device provides, therefore, less angular variation of intermediate transmittances compared with that provided by prior art liquid crystal light control devices.
