摘要： A height sensor for determining the height from a surface to be measured on the basis of an optical path length from a light-emitting element to the surface to be measured includes: a first light-emitting element and a second light-emitting element disposed at positions spaced apart from the surface to be measured; a mirror for reflecting at least one of a beam of light emitted from the first light-emitting element and a beam of light emitted from the second light-emitting element; and a light-receiving element for receiving the beams emitted by the first and second light-emitting elements and reflected by the surface to be measured and for outputting a signal corresponding to a quantity of light received. The mirror is arranged to cause respective optical paths of the beams emitted from the first and second light-emitting elements to be brought into close proximity to each other. Another mirror is provided for producing an optical path difference between the respective optical path lengths from the first and second light-emitting elements to the surface to be measured.

摘要： A multi-color image-forming apparatus having image-forming sections for a plurality of different colors can include an optical sensor having a light-casting section that casts single polarized light and a light-receiving section that receives polarized light different from the cast light. A pattern for detecting toner positions can be used in which toner having high reflectance to a particular light emission wavelength is independently formed. In addition, other patterns in which toner having low reflectance to the particular light emission wavelength are partially formed on a central portion of the pattern of high reflection toner by using the high reflection toner as a foundation. The apparatus can detect each toner pattern by the optical sensor to correct the color shift of each color.

摘要： The invention relates to an optical element being conveniently useful, for example as an external cover of transmitter and/or receiver for optical communication and more particularly to a surface-curved optical element comprising a transparent body of a refractive index n having a pair of boundary surfaces defined in their cross-section by the corresponding pair of ellipsoidal curves of an eccentricity 1/n. The boundary surfaces of this surface-curved optical element are configured so that they should have their focal points aligned with one another on a straight line and their focal points which are remote from vertices of the respective ellipsoidal surfaces corresponding to the apsides of the respective ellipsoidal curves should be coincident with each other, whereby parallel light rays entering the surface-curved optical element should emerge from this in the form of the parallel light rays without any disturbance.
