摘要： Positioning of a scan line (L) relative to a recording medium drum (15) of a polygon printer is established by independently adjusting blocks (35, 36) mounted on a scan line generating optics module (10) through adjustments made to an external beam sensing fixture (52). Inverted V-notches (38) used for nesting the blocks (35, 36) onto cylindrical surfaces of drum bearings (33) are nested onto corresponding cylindrical surfaces of fixture ends (54, 55). X, z, ϑ x and ϑ z positions are then set by x and z direction adjustment screws (44, 45, 49, 50) mounted on a support structure (73) to make adjustments in the fixture positions against the bias of springs (100). Clamping screws (45, 46) pass through oversized holes (47, 48) on blocks (35, 36) to releasably lock blocks (35, 36) after adjustment. The z direction adjustment includes levers (85) and dual ball socket assemblies (95, 96, 97) so that adjustment of the ϑ y position of fixture (52) will simultaneously occur to maintain a constant angle of incidence during adjustment, in response to the travel of a wheeled member (60) against a constant radius frame surface (70).

摘要： The light control system for the illumination system of a film telecine scanner comprises an aperture defining mechanism (35,36) and a position servo regulator that maintains the aperture at a desired aperture opening despite disturbances tending to change the aperture between aperture changes and an intensity servo regulator that takes into account the lamp intensity in resetting the aperture to a new position in response to a commanded light intensity related to a scene change, whereby aperture changes may be effected within the time of scanning a single film frame. The intensity servo regulator takes into account non-linear intensity gain of the aperture defining mechanism and its velocity of movement to establish a new aperture. The position servo regulator develops a position error signal by comparison of the instantaneous position to the previously set position and restores the previously set position. The aperture defining mechanism comprises first and second movable blades placed at a location in the optical path.

摘要翻译：用于胶片电视电影扫描仪的照明系统的光控制系统包括一个光圈限定机构（35,36）和一个位置伺服调节器，该光圈控制系统将光圈保持在所需的光圈开度，尽管干扰趋于改变光圈变化和强度伺服调节器，其响应于与场景变化相关的命令光强度，在将光圈重置到新位置时考虑到灯强度，由此可以在扫描单个胶片帧的时间内实现光圈变化。强度伺服调节器考虑孔径限定机构的非线性强度增益和其运动速度以建立新的孔径。位置伺服调节器通过将瞬时位置与预先设定的位置进行比较来产生位置误差信号，并恢复之前设定的位置。孔限定机构包括放置在光路中的位置处的第一和第二可动刀片。
