Abstract
An optical array includes one or more optical elements each including an incident surface at which light is incident into the optical element, a first reflection surface at which the light passing through the incident surface is reflected, a second reflection surface at which the light reflected by the first reflection surface is reflected again, an emission surface at which the light from the second reflection surface exits the optical element, and a refractive surface at which light that passes through the first reflection surface is refracted away from the emission surface.
Claims20
An optical array, comprising:
- one or more optical elements each including:
- an incident surface at which light can enter into the optical element;
- a first reflection surface at which the light passing through the incident surface is reflected;
- a second reflection surface at which the light reflected from the first reflection surface is reflected again;
- an emission surface at which the light reflected from the second reflection surface exits the optical element;
- and
- a refractive surface at which light passing through the first reflection surface from inside the optical element is refracted in a direction away from the emission surface.
An optical apparatus, comprising:
- a light source configured to emit light;
- and
- one or more optical elements each including:
- an incident surface at which light can enter into the optical element;
- a first reflection surface at which the light passing through the incident surface is reflected;
- a second reflection surface at which the light reflected from the first reflection surface is reflected again;
- an emission surface at which the light reflected from the second reflection surface exits the optical element;
- and
- a refractive surface at which light passing through the first reflection surface from inside the optical element is refracted in a direction away from the emission surface.
An image forming apparatus, comprising:
- a light source configured to emit light;
- one or more optical elements each including:
- an incident surface at which light can enter into the optical element;
- a first reflection surface at which the light passing through the incident surface is reflected;
- a second reflection surface at which the light reflected from the first reflection surface is reflected again;
- an emission surface at which the light reflected from the second reflection surface exits the optical element;
- and
- a refractive surface at which light passing through the first reflection surface from inside the optical element is refracted in a direction away from the emission surface;
- and
- an image forming unit configured to form a latent image according to the light emitted from the emission surface.
