Abstract
Apparatus wherein an image intensifier (16) is interposed between a plurality of emission sites (10) from which emanate photons and a photo-detector (20) coupled to the output of the image intensifier to produce separate electrical signals processed by computer (24) to enable the respective signals to be correlated to the sites of the original emission source.
Claims27
A high resolution optical imaging apparatus comprising a sample holder for carrying one or more samples, an image intensifier having an input face plate means adapted to be optically coupling the sample holder to the image intensifier so that said intensifier simultaneously receives on distinct regions of its input faceplate photon emission respectively emanating from differing sites on the sample holder, photo-electric detecting means coupled to the output of the image intensifier simultaneously to detect the respective photon emissions, and electronic means coupled to the photo-electric means to produce electrical output signals dependent on the photon emission received at the respective distinct regions of the faceplate, and a signal processing means for relating the respective output signals to the originating sites of photo emission by the sample or samples carried out by the sample holder.
A method of operating a microscope and image intensifier combination usable to view a sample carried by a sample holder, the image intensifier having distinct regions of its input faceplate individually coupled to differing sites on the sample holder, according to which positioning of the microscope for high magnification viewing of a site of interest is enabled by low magnification examination of the complete sample holder with the image intensifier.
