Description

Jig and Measuring Apparatus Including the Jig for Accurately Measuring the Characteristics of Mirror Surface The present embodiment relates to a jig capable of accurately measuring the characteristics of a mirror surface and a measuring device including the same. The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art. Optical mirrors are incorporated into various devices for diverse applications. Optical mirrors must be manufactured to possess the optical characteristics required by the device. However, due to the nature of the manufacturing process, tolerances may occur, and there may be cases where the finally manufactured optical mirror fails to meet the optical characteristics required during the design phase. As such, a measuring device exists to determine whether an optical mirror possesses the required optical characteristics. The measuring device irradiates light onto all parts of the surface of the optical mirror and senses the reflected light reflected from the surface of the optical mirror after irradiation to measure the optical characteristics of the optical mirror. Since the measuring device must irradiate light onto all parts of the surface of the optical mirror, it irradiates light while rotating the optical mirror after mounting it on its mirror stand. However, because the optical mirror rotates during the measurement process, the problem of the mounted optical mirror (the object to be measured) moving out of the correct position on the stand occurs frequently, and consequently, unintended errors have occurred in the measurement results. FIG. 1 is a drawing illustrating the configuration of a measuring device according to one embodiment of the present invention. FIG. 2 is a perspective view of a jig having an optical mirror arranged thereon according to one embodiment of the present invention. FIG. 3 is a cross-sectional view of a jig having an optical mirror arranged thereon according to one embodiment of the present invention. FIG. 4 is a plan view of a jig having an optical mirror arranged thereon according to one embodiment of the present invention. The present invention is susceptible to various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. Similar reference numerals have been used for similar components in the description of each drawing. Terms such as first, second, A, B, etc., may be used to describe various components, but said components should not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. The term "and/or" includes a combination of a plurality of related described items or any of a plurality of related described items. When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between. The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, terms such as "comprising" or "having" should be understood as not precluding the existence or addition of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which this invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. In addition, each component, process, procedure, or method included in each embodiment of the present invention may be shared within a scope that is not technically contradictory to one another. FIG. 1 is a drawing illustrating the configuration of a measuring device according to one embodiment of the present invention. Referring
