Disclosed embodiments include an energy waveguide system having an array of waveguides and an energy inhibiting element configured to substantially fill a waveguide element aperture and selectively propagate energy along some energy propagation paths through the array of waveguides. In an embodiment, such an energy waveguide system may define energy propagation paths through the array of waveguides in accordance to a 4D plenoptic system. In an embodiment, energy propagating through the energy waveguide system may comprise energy propagation for stimulation of any sensory receptor response including visual, auditory, somatosensory systems, and the waveguides may be incorporated into a holographic display or an aggregated bidirectional seamless energy surface capable of both receiving and emitting two-dimensional, light field or holographic energy through waveguiding or other 4D plenoptic functions prescribing energy convergence within a viewing volume. The waveguides may include different structures configured for each or all sensory system or energy domain to direct energy through refraction, diffraction, reflection, or other approaches of affecting the propagation paths of energy.

A highly reflective light-guide system has a highly reflective light-guide surface for reflecting light that has been emitted from a sample and has entered from an entry port opposing a window material and propagating the same to an exit port opposing a light reception surface of a photodetector. An optical filter is provided in a space surrounded by the window material, the photodetector, and the highly reflective light-guide system and transmits the signal luminescence to be measured that is emitted from the sample between the window material and photodetector. The optical filter is fixed to the window material or photodetector by an adhesive, and the peripheral shape of the optical filter is smaller than the shape of the inside of a fitting part to which the optical filter is fitted and that is formed on the highly reflective light-guide system.
