Abstract
An optical system device with a concave mirror, applicable for a scanner, comprising at least a curved reflection mirror and an image sensor. The curved reflection mirror is used for reflecting an image from an object to the image sensor. The curved reflection mirror can comprise a concave surface or a convex surface or both. At least a planar reflection mirror is located between the object and the curved reflection mirror, and is used to adjust a reflection angle and a reflection position of the image.

15. An optical system device with a concave mirror, applicable for a scanner, comprising:
-
a curved reflection mirror;
a plurality of planar reflection mirrors, locating at both sides of a surface of an optical axis of the curved reflection mirror in such a way that a space is formed close to the surface of the optical axis; and
an image sensor, located on the surface of the optical axis of the curved reflection mirror, wherein an image is reflected by the planar mirrors to the curved reflection mirror, the image is then reflected by the curved reflection mirror passing through the space to reach the image sensor.

17. An optical system device with a concave mirror, applicable for a scanner, wherein the device is used to receive an image from an object that has a desired surface, the device comprising:
-
a planar reflection mirror, reflecting the image;
a curved reflection mirror, wherein a surface of an optical axis of the curved reflection mirror is at an angle to the desired surface of the object; and
an image sensor, wherein the image of the object is reflected by the planar mirror to the curved reflection mirror, the image is then reflected by the curved reflection mirror to the image sensor. - View Dependent Claims (18)
