GENERAL:1.1 Scope:This standard covers the general requirement for the preparation and production of multicolor microchart/map transparencies for use with optical projection viewing devices. It defines the physical and photographic characteristics
33、of the output transparencies. These transparencies shall exhibit sufficient fidelity so that when projected back to the original size, the projected image shall be an acceptable facsimile of the original chart.1.2 Application:The transparency described in this standard is intended for use with optic
34、al projection display systems. The projected microchart/map image may be used in conjunction with automatic data processing systems, cathode ray tube (CRT) display or other auxiliary data sources to present a complete static and dynamic display of the operational situation. These transparencies may
35、be used with airborne navigation, land based, or shipboard projection systems.2.

For the purpose of this standard, all photographic terms not defined herein shall be in accordance with MIL-HDBK-25.3.1.1 Sensitometric Terms:3.1.1.1 Densit
40、y: The light-absorbing quality of a photographic image. It is the logarithm of the optical opacity, where the opacity is the ratio of the incident light to the transmitted or reflected light. It varies with the use of scattered or specular light.3.1.1.1.1 Total Density: The sum of the dye deposit de
41、nsity and the base plus fog density as defined herein.3.1.1.1.2 Fog Density: That which is produced on a piece of processed film by causes other than exposure to light such as chemical processes during development.3.1.1.1.3 Base plus Fog Density: For a Negative Film - the total density of processed
42、film that has not been exposed to light prior to development; For a Reversal Film - the total density of processed film that has received sufficient exposure to light, prior to development, such that any additional exposure will not produce a lower density.3.1.1.1.4 Net Density: The difference betwe
43、en total density and base plus fog density (applicable to negative color films).3.1.1.2 Gamma: A numerical designation for the contrast of a photographic material as represented by the slope of the straight-line portion of the characteristic curve. The Gamma is numerically equal to the tangent of th
44、e angle which the straight-line portion makes with the base line. A Gamma of 1 in a negative signifies that the range of density in the negative is the same as the range of light values in the subject photographed; a Gamma of .5 signifies that the range of density in the negative is one-half of the
45、range of the subject. Emulsion characteristics and development procedures directly affect the Gamma value.3.1.1.3 Average Gradient: The slope of the straight line drawn between two specified points on the H and D curve (Refer MIL-HDBK-25).3.1.1.4 Emulsion Number: A number assigned by the manufacture
46、r to identify a specific film production run.3.1.2 Physical Terms:3.1.2.1 Physical Defects: Scratches, pinholes, or other physical imperfections including streaks, spots, areas of uneven coating, bubbles, lap marks, lumps, foreign materials, etc.SAE AS13471 - 6 -3.1.2.2 Film Direction: The direction
47、 parallel to its forward movement in the base casting/extrusion machine. This is also termed “grain” or “machine direction.” The width direction also termed “cross direction,” shall be at right angles to the film direction in the plane of the sheet.3.1.2.3 Humidity Coefficient of Expansion: The aver
48、age change in dimension per unit distance per one percent change in relative humidity.3.1.2.4 Thermal Coefficient of Expansion: The average change in dimension per unit distance per one degree Centigrade or Fahrenheit change in temperature.3.1.2.5 Dimensional Change Due to Processing: The permanent
49、dimensional change caused by the wetting and drying of the sensitized material during photographic processing. The amount of change is obtained by measuring the processed and dried film after it has reached equilibrium in an atmosphere having the same relative humidity and temperature values as those which existed during the measuring of unprocessed film. The amount of change in film dimensions is expressed as a percentage.3.1.2.6 Dimensional Change Due to Processing Plus Aging: Permanent dimensional changes occur as a
