3 results about "Projection optics" patented technology

A present disclosure relates to a projector including a light source, an excitation light source, a wavelength converter, a collimator system that parallelizes fluorescence outputted from the wavelength converter, a light separator that separates the fluorescence into second light and third light, a correction lens provided in an optical path of the second or third light, a superimposing lens, a light modulator having a plurality of pixels each including first, second, and third sub-pixels, a microlens array including a plurality of microlenses corresponding to the plurality of pixels, and a projection optical apparatus. First light is incident on a first position on the superimposing lens, the second light is incident on a second position on the superimposing lens, the third light is incident on a third position on the superimposing lens The first light passes through the microlenses and is incident on the first sub-pixels. The second light passes through the microlenses and is incident on the second sub-pixels. The third light passes through the microlenses and is incident on the third sub-pixels.

An imaging system includes an image realisation device and projection optics for rendering a display image on a display screen. The image realisation device includes a first image realisation surface tilted relative to an optical axis such that a first point in a first region of the image realisation surface is at a first distance from the focal point of the projection optics and a second point in a second region of the image realisation surface is at a second different distance from the focal point of the projection optics. A first source image formed on the first region and projected through the projection optics renders the first display image on the display screen at a first apparent depth, and a second source image formed on the second region and projected through the projection optics renders the second display image on the display screen at a second apparent depth.
