Abstract: A target plate is provided in the operating field of view of a microscopic operating system having a plurality of target patterns thereon. These target patterns include scaled rulings, to which an operating element of the system is aligned, and reflective portions for calibrating the optical elements of the system to assure even illumination of the field of view and minimal distortion. Additional target patterns include centerline rulings which intersect at right angles for calibration of Theta alignment of an operating element, and at least one matte surface for examination of the pattern recognition capability to determine contrast and video information quality. At least one checkerboard pattern of alternating reflective and non-reflective surfaces and at least one continuously reflective surface may be provided to calibrate distortion, focus, illumination, and contrast.

Abstract: The brightness and density distribution of an object can be digitally measured photographically by exposing a light-sensitive photographic material at a dot screen or the like and to the object to be measured, and photographically processing the exposed light-sensitive material to produce equidensity images in which different densities of the object are differently represented.

Abstract: A step tablet with which an amount of exposure or degree of exhaustion of a developing solution can very readily been determined. The step chart is composed of a number of rectangular patches of photosensitive material, arranged in an order of sensitivity. The steps are each marked with two indicia, one having an optical density corresponding, upon development, of a step of minimum optical density, while the other corresponds to a step of maximum optical density.

Abstract: 969,811. Photomicrography; exposure control. ERNST LEITZ G.m.b. H. June 22, 1962 [June 28, 1961], No. 24076/62. Heading G2A. A light beam intensity control device for use in photomicrography comprises a device of variable light absorption arranged for insertion in a light path of a microscope by means controlled by a light sensitive member provided for measuring the intensity of the light beam after it has passed through the object so that the intensity of the light beam be adjusted for the exposure of photographic material of given sensitivity for a given exposure time. In the embodiment shown, light from a source ,1 passes through an object 5 which is photographed on a photosensitive surface 13 through a shutter 14. The shutter can be set to one of two speeds, one comparatively short the other comparatively long. For each speed the intensity of the light beam falling on surface 13 is varied by increase of a movable grey wedge or polarizing means controlled by a servomotor 19 and a control device 18. The device 18 is in turn controlled by a light sensitive element 17 on to which the light beam may be directed by means of a pivoted mirror 15. The object may be viewed by means of a half silvered mirror 7, reticule 9 and eye-piece 8.

Abstract: A step-wedge is reprinted four times, one for each of three colors plus black and white as a mask. The reprinting is in a different position each time, giving a total of four different positions with one selected value overprinted by each color to show the effect of the overprint, namely to demonstrate a neutral. If a neutral gray is obtained, then it is known that the printing is correct. If no neutral is obtained, a ready reference, not requiring the use of a densitometer or separation filters is immediately at hand.
