OPTICAL SYSTEMS INCLUDING LENS ASSEMBLIES AND METHODS OF IMAGING FIELDS OF VIEW USING SUCH OPTICAL SYSTEMS |
| 摘要 |
Optical systems including lens assemblies and methods of imaging fields of view using such optical systems are disclosed. An optical system for imaging a two dimensional field includes a first lens assembly, a first scanning mirror, a second lens assembly, and a two dimensional image sensor. The first lens assembly has a first transform function whose output is within 0.1% of f1*(c1*θ1+(1−c1)*sin(θ1)) for any ray of light that traverses the first lens assembly from a center of an entrance pupil of the first lens assembly at an angle θ1 relative to an optical axis of the first lens assembly. f1 is a focal length of the first lens assembly, and −0.5<c1<2. |

1. An optical system for imaging a two dimensional field comprising:
a first lens assembly having a first transform function whose output is within 0.1% of f1*(c1*θ1+(1−c1)*sin(θ1)) for any ray of light that traverses the first lens assembly from a center of an entrance pupil of the first lens assembly at an angle θ1 relative to an optical axis of the first lens assembly, wherein f1 is a focal length of the first lens assembly, and wherein −0.5<c1<2; a first scanning mirror; a second lens assembly having a second transform function whose output is within 0.1% of f2*(c2*θ2+(1−c2)*sin(θ2)) for any ray of light that traverses the second lens assembly from a center of an entrance pupil of the second lens assembly at an angle θ2 relative to an optical axis of the second lens assembly, wherein f2 is a focal length of the second lens assembly, and wherein −0.5<c2<2; and a two dimensional image sensor, wherein: the first lens assembly, the first scanning mirror, and the second lens assembly are positioned in an optical path between the two dimensional field and the two dimensional image sensor such that light from the two dimensional field traverses the second lens assembly, is incident on the first scanning mirror, is redirected into the first lens assembly by the first scanning mirror, traverses the first lens assembly, and is incident upon the two dimensional image sensor, thereby imaging the two dimensional field with the two dimensional image sensor. |
