摘要： An endoscope includes in order from an object side, an objective optical system, an optical-path splitter, an image sensor, and an image processor. A λ/4 wavelength plate is disposed between the objective optical system and the splitter. The splitter includes first and second prisms, and has a beam splitting surface at which the first prism and the second prism are brought into close contact. The splitter splits light at the beam splitting surface, into a first optical path through which P-polarized light is transmitted and a second optical path through which S-polarized light is reflected. The first and second prisms are slid relative to one another along the beam splitting surface to adjust optical path lengths of the first and second optical paths, and are disposed at positions to cancel an amount of shift in focusing positions of extraordinary and ordinary light, and satisfy specific conditional expressions.

摘要： A beam combining module combines a first beam corresponding to a first wavelength and a second beam corresponding to a second wavelength. The beam combining module includes a collimating lens, a first mirror, and second mirror. The collimating lens is configured to receive the first beam and the second beam that are parallel to each other and to emit the first beam and the second beam in respective non-parallel directions. The first mirror is configured to reflect the first beam emitted by the collimating lens. The second mirror is configured to reflect the second beam emitted by the collimating lens in a direction parallel to the first beam reflected by the first mirror and in such a manner that the second beam emitted by the collimating lens spatially overlaps the first beam reflected by the first mirror.

摘要： Disclosed is a high-stability nano-radian-order angle measuring method and device based on drift value feedback, belonging to the technical field of precision measurement and the field of optical engineering. The device consists of LED light sources, convex lenses, multi-slit diaphragms, beam splitters, deflecting mirrors, steering mirrors, a collimator objective set, linear array CCDs, a four-quadrant position detector and a plane mirror. The method includes: enabling two paths of measuring light beams to carry angle change information of a measured object, respectively forming respective images on two sensors, and calculating a pitch angle and a yaw angle of the measured object relative to an optical axis by using positions of the two images so as to achieve the detection capability on the angle change of the measured object. While a focal distance of the objective is greatly improved by using the collimator objective set, the linear array CCDs are used as sensors to improve a measuring range. Therefore, the technical advantage of nano-radian-order angle limit resolution is achieved under the condition of the same measuring range. The LED light sources, the convex lenses and the multi-slit diaphragms are used, and at the same time, drift value feedback is performed by using the four-quadrant position detector and the steering mirrors, and the system stability is improved to 10 nano-radian order, thus solving the problem of limitation of light beam drift value to limit resolution of an autocollimator. Additionally, a system device designed by the present disclosure has the technical advantages of small structure size, high measurement precision and high measurement frequency response.
