Abstract

A cubic-phase distribution is applied in the design of inexpensive lenses for passive infrared motion sensors. The resulting lenses have the ability to distinguish the presence of humans from pets by the employment of the so-called wavefront coding method. The cubic-phase distribution used in the design can also reduce the optical aberrations present on the system. This aberration control allows a low tolerance in the fabrication of the lenses and in the alignment errors of the sensor.
