OPTICAL ASSEMBLY FOR A LIGHT SENSOR
First Claim
1. An optical assembly comprising:
- a first optical element configured to receive light and alter a transmission path of the light through said first optical element in a first direction and a second direction; and
a second optical element in optical communication with said first optical element, said second optical element configured to receive the light from said first optical element, and alter a transmission path of the light through said second optical element in said first and second directions, wherein the light is passed through said second optical element, such that a light sensor receives light from a field of view that is approximately 30 degrees to 60 degrees offset from a field of view of the light sensor.
