IMAX projectors have been categorized into two groups, "True IMAX" and "LieMAX," based on the quality and size of their projected image.[1] IMAX venues that feature either 15/70 mm film projectors or IMAX with Laser projectors are considered True IMAX.[2] IMAX venues with solely 2K resolution digital xenon projectors or other projectors are not considered True IMAX.
Traditional 15/70 mm IMAX locations use 70 mm film projectors, with the film running through the projector(s) horizontally, each frame being 15 perforations wide.[3] Cinemas show 3D presentations using two projectors and either linear polarized or LCD shutter glasses. These locations are capable of displaying aspect ratios as tall as 1.43:1. Dual Laser locations use two 4K resolution digital projectors with laser light sources,[4] with 3D content similarly using wavelength multiplex visualization to Dolby 3D. Some are capable of displaying aspect ratios as tall as 1.43:1.
