<p>The invention features an imaging system (500) for imaging an object point (560) to an image point (562). The system includes: a beam splitter (550) positioned to receive light rays from the object point (560) and separate each ray into a transmitted portion and a reflected portion, the transmitted portions defining a first set of rays and the reflected portions defining a second set of rays; and a reflecting surface (532, 542) positioned to receive one of the sets of rays from the beam splitter and focus that set of rays towards the image point (562) via the beam splitter. Interferometric techniques may be applied to increase the light throughput of the system.</p> |
