Core Optical Design Terms

Term	Meaning
Calibration	The process of optimizing rendering to match the position of the attached lens.
OVD	Optimal Viewing Distance (Optical Viewing Distance).
FOV	Field of View.
HoloGlass	MOPIC's ultra-thin 3D Filter product. Silicone adhesion lets users attach and detach it themselves.
Crosstalk (X-talk)	Ghosting — the left and right images appear blended together.
Moiré	A striped pattern caused by interference between the pixel and lens patterns.
Transmittance	The proportion of light that passes through an optical layer.
Lenticular Lens	The standard lens used to achieve glasses-free 3D.
PiP Lens (Picture-in-Picture)	A lens that can display 2D and 3D at the same time.
Switchable 3D	A lens that switches the lens pattern on and off using an electrical signal.
3D Filter	The full stack of optical layers placed on the display (Lens Sheet + Gap Glass + protective layers, etc.).
3D Lens Sheet	An optical sheet with a precise pattern that refracts light from the display in a set direction.
Color Filter	The pixel layer that produces RGB color in an LCD.
Gap Glass	Glass used to fill the optical distance (Gap) between the 3D Lens Sheet and the Color Filter.
OCA	A transparent optical adhesive layer that bonds layers together (Optically Clear Adhesive).
PPI	The display's pixel density and pixel spacing (Pixels per Inch).
CL	The distance from the display's Color Filter to the Lens.
LP	Lens Pitch — the spacing between lenses.

Camera Types (for Eye Tracking)

Term	Meaning
Depth Camera	A camera that can measure viewing distance — Stereo / IR / ToF, etc.
Mono Camera	A camera that cannot measure viewing distance — a standard single-lens camera, webcam, etc.

3D Content Formats

Term	Meaning
Stereo	3D content that includes both left-eye and right-eye images.
Mono	Standard 2D content with a single viewpoint and no left/right view information.
HSBS	Stereo images placed side by side, with the horizontal resolution compressed to half.
FSBS	Stereo images placed side by side, keeping the original aspect ratio and resolution.
Top & Bottom	Stereo images arranged top and bottom.
2D + Depth Map	A 2D image plus depth information.
VR180 / VR360	VR content formats based on a 180° / 360° field of view, used in HMD environments.
Frame Packing	A resolution-preserving format used in Blu-ray and similar media.

Software Acronyms

Term	Meaning
SDK	A set of developer features and libraries (Software Development Kit).
API	An interface for integrating with external programs (Application Programming Interface).
OpenXR	A standard XR runtime for outputting game and CG content as real-time 3D.
