Abstract: The present invention relates to an off-axis infrared optical system with a concept of an asymmetric field of view. The area of the surface of the area, which is a monitoring criterion on the entire image screen, is vertically positioned below the center of an image to cause a monitoring image screen (20) of a ski area, whereby the attention is focused to occupy a relatively wide area, thus improving the monitoring effects. The position of the surface of the sea in regards to an object to be monitored is made by adjusting an incidence angle of infrared rays received to an object lens (7). By including an object lens adjuster (10) with an installation angle (x) coupled to the object lens (7), a vertical field of view above the surface of the sea can be made wide while making a vertical field of view below the surface of the sea of little interest narrow with respect to the incidence angle of the infrared rays. More specifically, a reference surface of the sea can be moved to a desired position with a field of view of the off-axis infrared optical system, thereby efficiently adjusting the field of view of a region of interest, reducing a load on the optical design, and improving performance.

Abstract: PURPOSE: An autofocusing device of electric optical imaging equipment and an autofocusing method thereof are provided to calculate a defocus size by directly measuring the optical guide surface phase information of light which is incident to the optical system, to confirm a focal state, and to rapidly adjust focus of the electric optical imaging equipment. CONSTITUTION: An autofocusing device of electric optical imaging equipment(20) comprises a Shack Hartmann wavefront sensor(10), an optical system(21), a space filter(17), and an imaging equipment signal processing unit. The Shack Hartmamn wavefront sensor obtains a point light source which forms a plurality of point images from a complex optical image of a target(50). The defocus size of the Shack Hartmann wavefront sensor is calculated by obtaining a partial inclination of a light guide surface which forms the point light force based on the displacement of the point image with a phase value simultaneously. The optical system includes a focal adjusting lens(22), a lens adjusting device(24), and a plane mirror(25). The space filter is installed at a position where an optical passage changed in the plane mirror is connected to the wavefront sensor. The imaging equipment signal processing unit is connected to imaging equipment detecting unit(28) which detects an image phase fallen on a focal surface(26) of the imaging equipment by being arranged in the rear side of the focal surface.
