1. A detection system for detecting an object, said detection system comprising:
- a transmitter at a first location comprising a light source configured to emit a first light beam having a first frequency towards the object at an incident angle, such that a second light beam is reflected from the object at a reflection angle, wherein the reflection angle is dependent upon the first frequency;
a receiver at a second location configured to receive the second light beam, wherein the second light beam has a second frequency as a result of a non-linear response of a surface of the object to the first light beam; and
a detector positioned within said receiver, said detector configured to detect the object based on the second frequency of the second light beam.

Abstract
A detection system for detecting an object includes a transmitter including a light source configured to emit a first light beam having a first frequency towards the object. The detection system also includes a receiver configured to receive a second light beam reflected from the object, and a detector positioned within the receiver. The second light beam has a second frequency as a result of a non-linear optical response of a surface of the object to the first light beam. The detector is configured to detect the object based on the second frequency of the second light beam.

12. A method of detecting an object, said method comprising:
-
emitting a first light beam having a first frequency from a first location towards the object at an incident angle, such that a second light beam is reflected from the object at a reflection angle, wherein the reflection angle is dependent upon the first frequency; receiving the second light beam by a receiver at a second location, wherein the second light beam has a second frequency as a result of a non-linear response of a surface of the object to the first light beam; and detecting the object based on the second frequency of the second light beam. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
