An alignment tool and a method are disclosed for alignment of a reflector arrangement. The reflector arrangement comprises a flat reflective surface which is configured to reflect an electromagnetic wave signal between a first antenna site and a second antenna site. The alignment tool comprises a camera circuit for capturing images of a field-of-view, an input circuit configured to receive a user input comprising the field-of-view coordinates of the first antenna site, a processing circuit configured to compute alignment information from the user input, and a display circuit configured to display the field-of-view and the alignment information.

An imager may include depth sensing pixels that provide an asymmetrical angular response to incident light. The depth sensing pixels may each include a substrate region formed from a photosensitive portion and a non-photosensitive portion. The depth sensing pixels may include mechanisms that prevent regions of the substrate from receiving incident light. Depth sensing pixel pairs may be formed from depth sensing pixels that have different asymmetrical angular responses. Each of the depth sensing pixel pairs may effectively divide the corresponding imaging lens into separate portions. Depth information for each depth sensing pixel pair may be determined based on the difference between output signals of the depth sensing pixels of that depth sensing pixel pair. The imager may be formed from various combinations of depth sensing pixel pairs and color sensing pixel pairs arranged in a Bayer pattern or other desired patterns.

An electromagnetic signal is received at first and second Superconducting Quantum Interference Device (SQUID) SQUID arrays. The first and second SQUID arrays output respective voltage signals corresponding to the electromagnetic signal as received at the first and second SQUID arrays. The first and second SQUID arrays are spaced apart such that there is a phase difference between the electromagnetic signal as received at the first and second SQUID arrays. The phase difference results in a voltage amplitude difference. At least one of the voltage signals is applied to at least one reference optical signal input into an electro-optical device to modify the reference optical signal. The modified optical signal output by the electro-optical device includes a change compared to the reference optical signal. The change is indicative of the phase difference in the electromagnetic signal as received at the first and second SQUID arrays.
