摘要： A lens position adjusting method for a zoom lens includes at least two movable lens groups, one lens group being primarily utilized for focusing and the other lens group being primarily utilized for magnification, wherein an object at a predetermined distance is in-focus when each movable lens group is positioned at each of respective initialized positions thereof with the zoom lens being set at a first focal length, and wherein each movable lens group is moved to vary magnification in accordance with a moving amount from the initialized positions of the movable lens groups. The lens position adjusting method includes: arranging a testing object at a position corresponding to a predetermined distance from the zoom lens; arranging a focal point detecting device at a reference focal plane or in the vicinity of the reference focal plane of the zoom lens; moving each movable lens group to each position at the first focal length; moving each movable lens group along an optical axis of the zoom lens so that a lens moving amount of each movable lens group is detected when a sharp image of the testing object is formed on the focal point detecting device via the zoom lens; making each of the positions of the movable lens groups as provisional initialized positions after completion of movement by the lens moving amount from the initialized positions; moving each movable lens group from the provisional initialized positions to positions at a predetermined focal length; detecting the lens moving amount by moving the movable lens group being chiefly utilized for focusing; obtaining a defocus amount from the lens moving amount; and obtaining an adjusting amount according to the defocus amount detected at given plurality of focal lengths so that each position of the movable lens group at which the in-focus state with the testing object is obtained at the first focal length serves as each adjusted initialized position.

摘要： A wavefront aberration compensating apparatus for an optical data recording and reproducing apparatus to correct a wavefront aberration of light emitted from a light source and converged onto a data recording medium through an image forming optical system includes a liquid crystal matrix. The matrix has several liquid crystal elements in a matrix arrangement, and is located in an optical path between the light source and the data recording medium. Each liquid crystal element can independently control a phase of light incident thereupon. The compensating apparatus also includes a liquid crystal controller which individually controls the liquid crystal elements to minimize the wavefront aberration of a beam spot converged onto the data recording medium. The invention is also directed to an optical data recording and reproducing apparatus having the wavefront aberration compensating apparatus incorporated therein.

摘要： A device including a polarizing beam splitter by which an incident luminous flux is split into a first luminous flux radiated onto a first photo sensor and a second luminous flux radiated onto a second photo sensor, and an adjusting mechanism provided for rotatably adjusting a position of one of the first and second luminous fluxes. The optical axis of the first luminous flux is coincident with that of the incident luminous flux. The optical axis of the second luminous flux is not parallel to the first luminous flux. By rotating the beam splitter about the optical axis of the first luminous flux, the beam receiving position of the second photo sensor, onto which the second luminous flux is radiated, is changed.

摘要： A scanning optical device that includes a light source that emits a light flux; a polygon mirror for deflecting the light flux; a scanning lens for converging the light flux deflected by the polygon mirror to form a beam spot on an image surface; a dynamic prism that is rotatably disposed between the light source and the polygon mirror to affect the direction of the light flux; a driving mechanism for rotating the dynamic prism to change the deviation angle of the dynamic prism; and a controller for controlling the driving mechanism to change the position of the beam spot during scanning. In particular, the controller rotates the dynamic prism to compensate for errors that affect the position of the beam spot on the image surface, such as errors that vary with time and errors that occur randomly during the scanning process.
