Diagram of the scanning apparatus. the interplay between these two controls, as well as the oscilloscope intensity, it is possible to obtain gated scans with intervals of one scan per ten minutes to fifty scans per second. The gated scan is transmitted optically to a microscope stage above the oscillo- scope via a camera lens mounted below the stage. The position of this lens can be adjusted by a fine-adjustment so that the scan may be focussed on a prepared slide of the organism to be observed. The area of the test preparation scanned is a 4-mm. square, while the depth of field is less than mm. The magnification of the subject may be changed by manipulating the horizontal and vertical sweep controls of the vertically mounted oscilloscope. The field scanned remains the same.
