The aperture is located on an incident light path. The primary mirror is located on an aperture side. The secondary mirror is located on a primary mirror reflected light path. The tertiary mirror is located on a secondary mirror reflected light path. The detector located on a tertiary mirror reflected light path. The primary mirror and the tertiary mirror have a same fifth-order polynomial freeform surface expression.

摘要： A method for designing an off-axis three-mirror imaging system with freeform surfaces is provided. A primary mirror initial structure, a secondary mirror initial structure, and a tertiary mirror initial structure are established. A number of first feature rays are selected, while the primary mirror initial structure and the secondary mirror initial structure unchanged. The first feature rays are forward ray tracked from an object space to an image detector. A number of first feature data points are calculated to obtain a tertiary mirror. A number of fields and a number of second feature rays are selected, while the secondary mirror initial structure and the tertiary mirror unchanged. The second feature rays are reverse ray tracked from the image detector to the object space. A number of second feature data points are calculated to obtain the primary mirror.

摘要： A design method of freeform imaging lens with a wide linear field-of-view (FOV) is provided. A initial freeform imaging lens is developed, and the initial freeform imaging lens includes a first lens surface and an entrance pupil spaced from each other, wherein the FOV of the system 2ω (±ω) is divided into 2k+1 sampling fields with equal interval Δω between each two adjacent sampling fields. Each two adjacent sampling fields are taken as one group. Two constraints are employed to calculate the plurality of data points of the first lens surface to obtain a front surface of the freeform imaging lens. The data points are calculated based on Snell's law, and a curve is obtained through the data points. A back surface is added to approximately keep the previous outgoing direction of rays from the front surface.
