摘要： Disclosed herein is a Uni-axis type lens module for a thermal imaging camera. The Uni-axis type lens module includes an object lens facing an object, receiving light from the object to capture an image of the object and transmitting visible rays and far infrared rays through one optical axis to integrate the visible rays and the far infrared rays; a beam splitter located behind the object lens in the direction of the optical axis, reflecting far infrared rays from lights that pass through the object lens and transmitting visible rays from the lights; a far-infrared imaging lens located in the direction of the optical axis of the far infrared rays reflected from the beam splitter, receiving the far infrared rays that reflect from a fold mirror and forming an image on a far-infrared sensor that converts an optical image into a thermal image signal; and a visible light imaging sensor located in the direction of the optical axis of the visible rays that pass through the beam splitter, arranged behind the beam splitter, receiving the visible rays that pass through the beam splitter and forming an image on a CCD sensor that converts an optical image into an actual image signal. Accordingly, images of visible rays and far infrared rays can be simultaneously captured to acquire distinct images.

摘要： An optical system for monitoring an alignment state of a large telescope comprises a primary mirror and an annular null mirror which is placed at the outside of a secondary mirror. The optical system functions as a null system, where the wave front of the reflected rays from the null mirror is consistent with the surface shape of the primary mirror in regional band. Since the null system uses a small annular lens on the outside of the secondary mirror, it has the advantages of light weight and small overall size.
