FOV without goggles
FOV with goggles, Pattern A
FOV with goggles, Pattern B
HORIZONTAL FOV
FOV without goggles
FOV with goggles, Pattern A
FOV with goggles, Pattern B
Answer the following question individually:
Calculate the “reduction factor”—that is, how much the goggles reduce the amount of light entering your eyes. This can be estimated by calculating the ratio between the “area of the world” that you can see (known as “solid angle”) without the goggles, and that which you can see with the goggles. Use the FOV results in radians.
Estimate the amount of light entering your eyes without goggles: Area 1 = = =
vertical FOV x horizontal FOV __________ x __________ ___________
Estimate the amount of light entering your eyes with goggles (Pattern ________ ): Area 2
= = =
vertical FOV x horizontal FOV __________ x __________ ___________
Reduction factor = =
Area 1 / Area 2 _____________
Repeat this calculation for the other goggle pattern. PolarHusky.com © NOMADS Online Classroom Expeditions GoNorth! Beringia 2011 Curriculum 109
