技术领域 FIELD

[0001] 本发明涉及一种光学测量的装置以及方法。 [0001] The present invention relates to an optical measuring apparatus and methods.

[0063] 以下将开始依序说明本发明的优选实施例的一种光学测量装置以及方法。 [0063] The following will describe a start sequence and a method of optical measuring apparatus of the preferred embodiment of the present invention.

[0064] 首先,请先参考图2A、图2B、图2C以及图3,图2A是本发明的光学测量装置的第一实施例的示意图,图2B、图2C分别是图2A的参考镜组放大示意图。 [0064] First of all, please refer to FIGS. 2A, 2B, 2C, and 3, FIG. 2A is a schematic first embodiment of an optical measuring apparatus of the present invention, FIG. 2B, 2C are reference mirror group 2A of FIG. an enlarged schematic view. 图3则为本发明光学测量装置的步骤流程图。 While Figure 3 shows the step of the optical measuring apparatus of the present invention a flowchart.

[0065] 本实施例的光学测量装置2至少可包括光源模块20、光耦合模块24、参考镜组22以及处理单元26。 Optical measurement apparatus [0065] Example 2 of the present embodiment may include at least a light source module 20, the optical coupling module 24, a reference mirror group 22 and a processing unit 26.

[0066] 光源模块20可提供光线。 [0066] The light source module 20 may be provided. 并且如果应用于人眼的角膜、视网膜测量时,为了顾及被测量者的舒适程度,则此光源模块20可为宽带激光光源。 And if applied to the cornea of ​​a human eye, the retina measurement, in order to take into account the comfort level of the measured subject, this light source module 20 may be a broadband laser. 例如,若应用于视网膜则波长可调整成约840nm,应用于角膜则可调整成1060nm或是1310nm,若应用于皮肤则可调整成约1310nm,光源模块的频宽约为20nm至40nm。 For example, if applied to the retina is adjusted to a wavelength of about 840 nm, applied to the cornea can be adjusted to 1060nm or 1310nm, when applied to the skin can be adjusted to about 1310nm, the light source module bandwidth of about 20nm to 40nm. 换言之,实际的波长跟频宽将依据应用的对象不同而有所调整。 In other words, the actual wavelength with the bandwidth depending on the application objects will be adjusted.

[0067] 光耦合模块24可将光源模块20的光线分别传递、汇聚至参考镜组22以及待测物01。 [0067] The optical module 24 may be coupled to the light source module 20 are transmitted, the convergence to the reference mirror groups 22 and 01 analytes. 本实施例的光稱合模块24可为分光器,但不局限于分光器。 This embodiment the light module 24 can be engaged, said beam splitter, but not limited to the beam splitter. 例如可将光源模块20的50%的光线反射进入参考镜组22,而其余50%的光线穿透进入待测物01,以达成光耦合的效果。 For example, 50% of the light source module 20 into the reference light reflecting mirror group 22, while the remaining 50% of the light penetration into the sample substance 01, to achieve optical coupling effect. 此外,本实施例的待测物01为一个球状体,且以眼球为例示,但不局限于测眼球。 In addition, the analyte 01 embodiment is a spheroid, and eyeball illustrative, but not limited to measuring the eye.

[0068] 本实施例的参考镜组22可包括致动器221 (micro-actuator)以及反射镜222,反射镜222为可挠性材质所构成,贴附于致动器221。 [0068] Example embodiment of the present reference mirror set 22 may include an actuator 221 (micro-actuator) and a reflecting mirror 222, the mirror 222 is composed of a flexible material, attached to the actuator 221. 致动器221可依据处理单元26提供的调整信号调整反射镜221的曲率,例如可调整成凸面(图2B)、凹面(图2C)或平面(图2A)。 The actuator 221 can be based on the curvature of the processing unit 26 provides the mirror adjustment signal 221, for example, be adjusted to the convex surface (FIG. 2B), the concave (FIG. 2C) or a plane (FIG. 2A). 具体而言,致动器221可依据不同的调整信号调整其形变的程度,进而使得反射镜222的曲率改变,以得到较好的测量结果。 Specifically, the actuator 221 may be different according to the degree of adjustment signal to adjust its deformation, thereby making the mirror 222 to change curvature to obtain a better measurement results. 详细的调整信号产生的方式将在下面描述。 The adjustment signal generated in detail will be described below.

[0069] 此外,本实施例的参考镜组22得以往复移动(例如可通过传动平台移动),以取得较好的干涉结果。 [0069] Further, the reference mirror group 22 of the present embodiment is reciprocated (e.g. a movable platform via a transmission), interference to achieve better results.

[0070] 实际应用时,首先,光源模块20可提供一个光线至参考镜组22,并提供又一光线至待测物(步骤SI)。 [0070] In practice, the first light source module 20 may provide light to a reference mirror group 22, and further to provide light to the object to be detected (step SI). 以本实施例的架构而言,光源模块20的光线可经由光耦合模块24传递至参考镜组22以及待测物01。 In the architecture of the present embodiment, the light source module 20 may be transmitted to the reference mirror 22 and the group of analytes 01 via the optical coupling module 24.

[0071] 接着,光线被参考镜组22反射后形成第一光线、光线将会被待测物01反射后形成第二光线。 [0071] Next, the reference light is formed in the rear lens group of the first reflected light 22, the light beam will be formed after the second reflection analyte 01. (步骤S2)。 (Step S2). 简言之,传递至参考镜组22、待测物01表面的光线都被反射。 Briefly, groups transmitted to the reference mirror 22, the surface 01 of the light is reflected analyte. 此时,通过光耦合模块24,被反射的第一光线与第二光线被传递至处理单元26。 In this case, 24, the first light and second light is reflected is transmitted to the processing unit 26 through the optical coupling module.

[0072] 第一光线与第二光线产生干涉(步骤S3)。 [0072] The first light and the second interference light (step S3). 此时,处理单元26可纪录此时第一光线与该第二光线的相对的光学路径长(光程差,0PD),以作为后续判断的依据。 At this time, the record processing unit 26 may have a relative optical path of the first light beam and the second length (optical path difference, 0PD), as a basis for subsequent determination. 详细而言,处理单元26可包括一个储存单元,其中可储存不同的光学路径长对应的干涉结果,亦即可通过查表的方式判断此步骤图为判断光学路径长是否符合预定干涉范围,若否,则依据干涉产生一个调整信号,参考镜组22依据调整信号调整参考镜组。 Specifically, processing unit 26 may include a storage unit which can store different optical path length corresponding to the result of the interference, this also can be determined by a table lookup step determines whether the picture shows the optical path length interference meets a predetermined range, if NO, then generating an adjustment signal based on the interference, the reference mirror groups 22 according to the reference mirror adjustment signal group. (步骤S4)。 (Step S4).

[0073] 以本实施例的架构为例,处理单元26将会依据第一光线与第二光线的干涉结果查找对应的修正方式(处理单元26内将会有一个数据库可对应查找干涉结果对应的调整方式,例如增加或减少曲度)以提供一调整信号。 [0073] In an example embodiment of the present architecture of the embodiment, according to the first processing unit 26 will light and the second light interference results in a manner corresponding to find correction (there will be a processing unit 26 may correspond to a database to find the corresponding result of the interference adjustment method, for example, increased or decreased curvature) to provide an adjustment signal. 接着,处理单元26会将调整信号传送给参考镜组22,参考镜组22将依据调整信号调整参考镜组22 (亦即致动器221将会使反射镜222产生形变,改变反射镜的曲率)。 Next, the transmission processing unit 26 will adjust the signal to the reference mirror group 22, the reference mirror groups 22 according to the adjustment signal sets the reference mirror 22 (i.e. the actuator 221 will deform the mirror 222, the mirror curvature change ).

[0074] 例如,可将参考镜组22预设曲率为O (亦即预设为一平面),进行第一次测量,接着再将参考镜组22的曲率调整成凸面及凹面,再分别针对凹面及凸面进行测量。 [0074] For example, the reference mirror group 22 of predetermined curvature O (i.e., programmed to a plane), the first measurement and then again adjusted to the curvature of the reference lens group convex surface and a concave 22, and then for each concave and convex were measured. 此时处理单元26将会比对这些测量结果,将参考镜组22调整至与待测物较为接近的曲率,以得到较精准的测量结果。 At this time, the processing unit 26 will adjust the ratio of these measurements, the reference mirror 22 to set the curvature closer to the analyte, to obtain a more accurate measurement result.

[0075] 或者,在约略知道待测物表面的曲率范围的情况下(例如已知测量者的年龄且欲测量角膜的情况),此时,在测量前处理单元26可依据数据库的查找该年龄的角膜曲率的平均值,将此平均值设定为第一次测量时参考镜组22的曲率,并由此曲率作为后续调整的基础。 [0075] Alternatively, in the scope of curvature approximate knowledge of the surface of the analyte (e.g., age, and those known measurement of the cornea to be measured), the case, at the age of 26 can be found before the measurement processing unit according to the database reference mirror group 22 of the average value of the curvature of the corneal curvature, this average value is set as the first measurement, and thus the curvature as the basis for subsequent adjustment. 也可以先将参考镜面调整至凸面(角膜为一凸面),再逐步减少凸面曲率,并测量反射的第二光线与第一光线的干涉情况,若干涉情况较差,则处理单元将会传送调整信号停止减少凸面曲率,并增加凸面曲率直至测量到最佳值为止。 Reference may be first adjusted to a convex mirror (the cornea is a convex surface), and then gradually reduce the curvature of a convex surface, and a second measure for interference light reflected to the first light, the case when the interference is poor, then the processing unit will send the adjustment signal is stopped to reduce the curvature of a convex surface, and the curvature of the convex surface increases until the measurement until the optimum value.

[0076] 简言之,通过上述方式调整后的第一光线与第二光线的干涉结果将会更加精准,并可测量出待测物01的表面曲率。 [0076] In short, the first result of the interference light is adjusted by the above-described second embodiment and the light will be more accurate, and can measure the surface curvature 01 of the analyte. 补充说明的是,上述的修正方式是以使参考镜组22的表面曲率调整至与待测物01的表面相似的曲率或是相似的曲率范围的方式。 It is added that the above-described embodiment correction is set so that the reference mirror 22 is adjusted surface curvature similar to the curvature of the surface 01 or a similar range to the curvature of analyte manner. 而且,可依据不同的需求,反复测量并加以调整至所需的精度。 Further, the repeatedly measured and adjusted according to the desired accuracy of the different needs.
