摘要:
An optical instrument for producing an optical image to be viewed by an observer, the optical instrument comprising: an optical system for producing an optical image of an object which is viewable by an observer at an exit pupil; and a diffractive element located at an image plane of the optical system for producing an array of the exit pupils, which are perceivable as a single, enlarged exit pupil by the observer.
摘要:
Optical instrument, e.g. microscope, for producing an image and comprising a diffractive element (25) located in an image plane (SIP) for producing an array of exit pupils which are perceivable as a single, enlarged, exit pupil by the observer. The diffractive element (25) comprises an array of units (39) being lenticules (41) producing diffractive interference generating the plurality of exit pupils.
