摘要:
A non-contacting aligning method for planes in a three-dimensional environment is disclosed. The method includes: projecting a light beam in a predetermined incident angle onto a transparent first object and an opaque second object that are facing each other; and calculating a distance between the first and second objects basing on the tangent trigonometric function of the incident angle of the light beam.

摘要:
The invention is about cascading high-transition-temperature superconducting quantum interference devices (SQUIDs) for sensing magnetic fields. These SQUIDs in series are connected with coils for picking up detected magnetic signals. Depending on the patterns of pick-up coils, magnetometers or gradiometers, which sense the magnetic field intensity and magnetic field gradient respectively, are achieved. Examples of magnetometers and gradiometers includes cascading high-Tc SQUIDs in series are provided.
