Microphotographic exposure control using 2-D photoelectric receiver

摘要

The intermediate image (2) is enlarged by a photo-eyepiece (3) adjacent to a mirror (7) which can be pivoted out of the beam so that with the central shutter (4) of an objective lens (5) opened, an enlarged intermediate image (6) is formed in the plane of the photographic film. The mirror diverts the image on to a CCD matrix (9) connected to a processing unit (PC). A beam splitter (ST) and binocular tube (10) enable the first intermediate image (2) to be studied by the observer (11).
