Abstract:
1. A method of imaging an object comprising: using a light source to emit light along a first optical path including an object to be imaged, and along a second optical path that is spatially separated by a splitter from the first optical path at the object to be imaged; combining light from the first optical path and light from the second optical path such that the combined light is incident on a two-dimensional imaging device having a plurality of pixels, the two dimensional imaging device receiving light along the first optical path that is tilted at an angle relative to the second optical path such that the incident light at the two-dimensional imaging device is received at different angles; detecting a two dimensional image of the object with the two-dimensional imaging device; and processing the two dimensional image with a Hilbert transform to obtain quantitative image data.
