Abstract
A dual-mode optical and RF reflector, and test system using the same. In one example the reflector is a mirror having a reflective surface including a first zone having a first surface precision, wherein a remainder of the reflective surface outside of the first zone has a second surface precision that is substantially lower than the first surface precision, the mirror being configured to collimate and reflect an RF signal from the reflective surface, and to collimate and reflect an optical signal from the first zone.
Claims17
A dual-mode optical and radio frequency (RF) reflector comprising:
- a mirror having a reflective surface including a first zone having a first surface precision, a remainder of the reflective surface outside of the first zone having a second surface precision that is substantially lower than the first surface precision, the mirror being configured to collimate and reflect an RF signal from the reflective surface, and to collimate and reflect an optical signal from the first zone.
A multi-mode alignment test system comprising:
- a test chamber;
- a multi-mode signal emitter configured to emit at least a radio frequency (RF) signal and an optical signal;
- and
- a dual-mode optical and RF reflector including a reflective surface configured to collimate and reflect the first RF signal into a test volume within the test chamber, and a zone within the reflective surface and corresponding to a portion of the reflective surface that is less than an entirety of the reflective surface, the zone being configured to collimate and reflect the optical signal into the test volume.
