1. A miniature scan-free optical tomography system, comprising:
a broadband light source emitting a light beam; a detection device without a grating in front of it; a beamsplitter splitting the light beam emitted from the broadband light source into a first reference light beam and a first sample light beam; an optical delay device comprising a fixed single curved reflecting surface reflecting the first reference light beam from the beamsplitter into a second reference light beam and causing the second reference light beam to have different optical path lengths along and only along a first dimension, wherein the second reference light beam reflected from the optical delay device is incident through the beamsplitter to the detection device; and a focusing device focusing the first sample light beam from the beamsplitter along and only along a third dimension, wherein a second sample light beam reflected from the sample is incident through the beamsplitter to the detection device, wherein different portions of the second reference light beam along the first dimension have different optical path lengths, wherein the broadband light source, the detection device, the beamsplitter, the optical delay device and the focusing device are integrated and configured to be sealed in a capsule-like compartment without any mechanism for scan or phase shift. |
