The problem of 3D panel display systems either (a) requiring special glasses to separate left and right viewing images, or (b) having auto-stereoscopic 3D with compromised fidelity, is solved by providing a projection three dimensional (3D) display system for providing glass-free, 3D display to a plurality of viewing volumetric pairs (VVAs) in space corresponding to a hypothetical plurality of viewers' eye aperture pairs, the projection 3D display system comprising: (a) a dual-image projector configured to project both a left viewing tri-color image and a right viewing tri-color image; and (b) means for (1) receiving a tri-color mixed input beam encompassing the left and right viewing tri-color images, (2) multiplying the tri-color mixed input beam into a plurality of tri-color mixed output beams, and (3) focusing the plurality of tri-color mixed beams for viewing at the VVAs.

The problem of 3D panel display systems either (a) requiring special glasses to separate left and right images, or (b) having auto-stereoscopic 3D with compromised fidelity, is solved by providing, for each of a plurality of left and right sub-pixels, both (1) means for separating the left and right image signals (e.g., alternating wedges, prisms, off-axis self-sourcing pixels, etc.), and (2) means for multiplexing the separated left and right signals to a plurality of viewers (e.g., gratings, such as amplitude gratings, phase gratings, etc.), such that (1) the left image is provided to a plurality of virtual volume apertures (VVA) containing positions of the left eyes of the plurality of viewers, and (2) the right image is provided to a plurality of virtual volume apertures (VVA) containing positions of the right eyes of the plurality of viewers. Glass-free 3D systems consistent with the present invention may treat far field optical signals from the display panel as electro-magnetic waves (and therefore treat diffraction and interference properties as significant, dominating far field optical distribution) rather than as rays consistent with geometric optical theory.

A fiber optic bioprobe in which an immobilized biolayer, such as an antigen or antibody, acts as a sensing etalon of a Fabry-Perot interferometer. The bioprobe is used in a system in which a shift in the spectral dispersion pattern, caused by reflected out-of-phase beams, is used to determine a concentration of a substance in a sample solution.
