查询词典 diaphragm shutter

In this method,light was adjusted by combining external trigger electronic shutter mainly and iris diaphragm assistantly.

该方法采用外触发电子快门和可变光阑相组合的方式进行调光，外触发电子快门调光为主，可变光阑调光为辅。

The condenser is equipped with an iris diaphragm, a shutter controlled by a lever which is used to regulate the amount of light entering the lens system.

聚光镜装配有瞳孔膜，那是一个有贡杆控制的快门，用来调节进入镜头系统的光量。

For example,when the camera moves from a sunlit to a shaded area within a shot ,it is often necessary to change exposure. The iris diaphragm of the lens can be changed,but this would change the depth of field and may be more noticeable than shutting down the variable shutter .

例如，一次摄像中当相机把镜头从阳光充足的地方移动到阴暗的地方时，必然需要改变曝光大小，镜头的可变光圈可以改变，但可能会影响景深，回比你关闭可变快门影响效果更大。

Light was adjusted by combining external trigger electronic shutter mainly and iris diaphragm assistantly.

该方法采用外触发电子快门和可变光阑相组合的方式进行调光，外触发电子快门调光为主，可变光阑调光为辅。

For a moderate image illumination, the electronic shutter time of CCD camera was adjusted by external trigger and the aperture of iris diaphragm was adjusted by motor controlled by single-chip.

采用外触发方式实现CCD摄像机的电子快门时间调节，由单片机控制电机调节可变光阑的通光口径，以使像面照度适中。

Ultraviolet light is made to projected successively to sample template, phase template and fiber or successively to diaphragm, shutter, phase template and fiber.

它是使紫外光依次入射到取样模板、相位模板和光纤上，或依次入射到光阑、快门、相位模板和光纤上。

The distance between the phase template and the fiber so as to obtain the sample rate at two ends of fiber approach zero; light beam is scanned via sample template, diaphragm or shutter in uniform speed and projected to fiber to expose and form periodical sample structure.

调整相位模板和光纤间的距离，使光栅两端的取样率接近于零；再使光束匀速扫过取样模板或光阑、快门而入射到光纤上曝光形成光栅的周期性取样结构。
