High-speed video camera and method of high-speed imaging using a beam splitter

摘要

In a high-speed video camera, a light beam from a main lens (3) is split into a plurality of light beams having identical optical information, and then these plurality of light beams are intermittently transmitted to different positions of an imaging device (11) in sequence. As a beam splitter may be used a multi-lens assembly (8) or a prism (14) having a plurality of light-receiving surfaces. In order to intermittently transmit the plurality of light beams in sequence to the imaging device, an image-selecting rotary shutter (12) having a fan-shaped opening (12a) is used. This shutter (12) and another shutter (5) for defining exposure time are synchronized with each other, and also synchronized with a vertical sync signal from a sync generator. In order to establish synchronization an adjustable delay circuit (38) is used.
