OPTICAL FILTERS 

A filter wheel is required that employs four different filters any one of 

which can be used at a given time. Generally, the filters will include a clear 

glass filter, neutral density, and haze filters. The clear glass filter, of which 

only one is needed, serves as a dummy optical element to maintain system 

oberration balance and focus when no functional filters are being used. To determine the requirements of the other filters, the content of the viewed scene 

must be analyzed. 

Carman and Caruthersl made a study of the distribution of scene luminance 

and luminance differences for a variety of terrain types as viewed from an aircraft flying at 4000 ft. altitude. The recording photometer scanned the terrain 

with a spot diameter of 3 feet. In every case, the luminance distribution was 

very nearly normal. The following table describes the scene content in terms 

of an assumed normal distribution. 

Sun Altitude - 64° 

Weather - Clear or Light Haze

The table indicates the luminance levels to be expected without the 

addition of the atmospheric haze associated with an orbital mission. On a 

clear day the maximum addition due to haze is about 750 foot-lamberts. Sunlit 

clouds 2

, however, reach levels of 10,000 ft.-lamberts, snow 5000 ft.-lamberts 

and sea glint much higher than either. Neglecting the latter phenomenon (because 

it is analyzed and found to be of minor effect in another study), let us assume 

that the mean scene luminance level that is to be attenuated is 3000 ft.-lamberts.

Introducing the 44,system transmission of 35% this quantity becomes very nearly 

1000 ft.-lamberts. The previous reference2 lists minimum illumination levels 

for various activities verying from 2500 lumens/ft. 2 for a hospital operating 

table to 3 lumens/ft. 2 for candle light dining. Perhaps the activity nearest to 

that of the at system function is that of engineering drafting. The recommended 

level for drafting room work is 100-200 lumens/ft.

2

. A white piece of drawing 

paper on a drafting table would have a luminance of roughly the same numerical 

value, 100-200 ft.-lamberts. Let us assume that the system image should 

have a mean luminance of 100-ft.-lamberts. The required neutral density filter 

must attenuate by a factor of 10:1. Its density is 1.0. Because of the constancy 

of mean scene luminance, as evidenced by the above table, it is recommended 

that only one neutral density filter be used. Haze, on the other hand, is quite 

variable. It is therefore recommended that the other two filters be used for 

cutting two relatively different levels of haze. 

The spectral content of the scattered light making up the haze varies with 

the amount of haze. When haze is very low, on a relatively clear day, scattering 

is predominantly at the shorter visible wavelength, the blue end of the spectrum. 

Scattering is then proportional to X -4. For heavier haze, such as that of an 

overcast day, the scattered light is primarily white indicating that the scattering 

is then ideally proportional to A (3 . 

Any haze spectral filter, in order to be of any use, according to the above 

analysis must be one that filters out the shorter wavelengths. Typical minus 

blue filters, such as these, transmit very little blue light, cutting on (50% level) 

at about 470 m/u. With heavier haze, light begins scattering at even longer 

wavelengths requiring that the cut-on wavelength must also be longer. In order 

to preserve some transmission, and for want of any other sources of definition, 

let us recommend a filter that cust on at 510 m/u. Both of the above can be 

represented by Kodak Wratten Filters #6 and #9.
