N2 - In this research, a sensor performance measurement technique is developed similar to the Triangle Orientation Discrimination (TOD), but sinusoids are used instead of triangles. Also, instead of infrared systems, the technique is applied to the eye and direct view optics. This new technique is called Contrast Threshold Function Orientation Discrimination (CTFOD) and the result is a "system" contrast threshold function that can be used with Vollmerhausen's Target Task Performance (TTP) metric. The technique is a simple technique that can be measured in the field using a target board where the results provide for the eye, the optics transfer function and transmission, and any atmospheric turbulence effects that are present.
