Camera modules are assembled in wafer arrays from arrays of image sensors, arrays of lens structures and arrays of optical trim elements. At least one of the arrays is a wafer. Lens structures are configured to provide less optical power than necessary to focus an image at infinity on image sensors without trim elements. A test performed during the wafer scale assembly of camera modules, after at least the sensor array and the lens structure array assembled, determines optical errors by identifying optical distortions and aberrations quantified in terms of optical power, astigmatism, coma, optical axis shift and optical axis reorientation deficiencies. Corresponding trim elements are configured to counteract distortions and aberrations prior to singulating useful camera modules from the array.

A compact camera modules has first, second, and third lens groups that move along an optical axis. A stepping motor is centered on the optical axis rather than offset from the optical axis. The motor has two coils that are fixed in place and a shared rotating magnet. The magnet is attached to a rotating guide that has slots to move the first and second lens groups as it rotates. The two coils are alternately energized rotate the magnet, the rotating guide, and to move the first and second lens groups for zoom. The magnet has alternating thicker and thinner segments of opposite polarity. The thicker segments exert a greater force on an autofocus coil that is energized to move the third lens for the autofocus function. The same shared rotating magnet is used for both zoom and autofocus functions. A more compact design is possible using a shared magnet.

The catadiotropic anamorphic optical system utilizes one or more cylindrical/acylindrical lens elements to image the modulated light field in the cross-process direction, and one or more cylindrical/acylindrical mirror elements to image and concentrate the modulated light field in the process direction. The line image is generated with sufficient energy to evaporate fountain solution from the imaging surface. The imaging system simultaneously generates all component pixel images of the line image, thus facilitating a printing apparatus capable of 1200 dpi or greater.

Single-Pass Imaging System With Anamorphic Optical System

Номер: US20130050669A1
Автор: Patrick Y. Maeda
Принадлежит: Palo Alto Research Center Inc

An single-pass imaging system utilizes a light source, a spatial light modulator and an anamorphic optical system to form a substantially one-dimensional high intensity line image on an imaging surface (e.g., the surface of a drum cylinder). The light source and the spatial light modulator are used to generate a relatively low intensity two-dimensional modulated light field in accordance with an image data line such that each pixel image of the line is elongated in the process (Y-axis) direction. The anamorphic optical system utilizes a cylindrical/acylindrical optical element to anamorphically image and concentrate the modulated light field in the process direction to form the substantially one-dimensional high intensity line image. The line image is generated with sufficient energy to evaporate fountain solution from the imaging surface. The imaging system simultaneously generates all component pixel images of the line image, thus facilitating a printing apparatus capable of 1200 dpi or greater.

The present application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2012-023896 filed on Feb. 7, 2012 and Japanese Patent Application No. 2013-1056 filed on Jan. 8, 2013; the entire contents of which are incorporated herein by reference.1. Field of the InventionThe present invention relates a zoom lens and an image pickup apparatus equipped with the same.2. Description of the Related ArtIn recent years, digital cameras that pick up an image of an object using a solid state image pickup element such as a CCD or CMOS have replaced film cameras and become the mainstream. Furthermore, various categories of digital cameras ranging from popular-priced compact type cameras to function-rich cameras for professionals have been developed.Users of popular-priced digital cameras wish to enjoy easy shooting in various shooting situations anywhere at any time. For this reason, such users favor small size digital cameras, especially slim digital cameras that can be conveniently carried in a pocket of clothes or a bag. Therefore, a further reduction in the size of the taking lens system is demanded.Moreover, while a wide angle of view is demanded in terms of the zoom range, image pickup apparatuses equipped with a zoom lens having a configuration that can be manufactured at low cost while having high optical ...
