Abstract
An optical assembly is provided wherein the optical assembly includes a first optical element and a second optical element. The first optical element is configured to receive light and alter a transmission path of the light through the first optical element in a first direction and a second direction. The second optical element is configured to receive the light from the first optical element, and alter a transmission path of the light through the second optical element in the first and second directions. The light is passed through the second optical element, such that a sensor receives light from a field of view that is approximately 30 degrees to 60 degrees offset from a field of view of the sensor.
