The holographic Near Eye Display, is also referred to as Head Mounted Display, which projects the images into the viewer’s eyes, creating a virtual image within the field of view. The virtual image appears within 1 meter distance from the viewer’s eye point to image projection and appears larger due to the magnification of the optics used to create the image.

Optical Imaging is an emerging medical technology that uses light to assess optical properties of tissues, and has a great potential for improving disease prevention, clinical research, medical diagnosis and treatment. The basic principle involves the detection of emitted photons at pre-defined wavelength ranges when the fluorescent probes in the optical imaging system can be excited by NIR light. Further advancements and breakthroughs in the field of fiber optics and photonics resulted in the emergence of innovative technologies such as Optical Coherence Tomography (OCT), Photo-Acoustic Tomography
