1. An optical projection tomography system for imaging an object of interest, the optical projection tomography system comprising:

  • (a) a light source;

    (b) an object-containing tube, a portion of which is located within the region illuminated by the light source, wherein the object of interest has at least one feature of interest located within the object-containing tube;

    (c) at least one detector, wherein the at least one detector is located to receive emerging radiation from the object of interest; and

    (d) at least one lens located in the optical path between the object region and the at least one detector, wherein the at least one lens includes at least one optical field extension element such that light rays from multiple object planes in the object-containing tube simultaneously focus on the at least one detector.
