Description
Technical field
The present invention relates to Accentric detector, particularly a kind of Accentric detector for detection of the eccentricity of glasses lens degree.
Background technology
Develop rapidly along with multimedia technology, digital camera (sees also Capturing images with digitalstill cameras, Micro, IEEE Volume:18, issue:6, Nov.-Dec.1998 Page (s): 14-19), video camera and favored by consumers in general with the mobile phone of camera, when the quality of image of people's logarithmic code camera, video camera and mobile phone cam shot object proposed requirements at the higher level, the product consumptions such as mobile phone that logarithmic code camera, video camera reach with camera were also increasing.In the first-class camera of digital camera, video camera and cell-phone camera, camera lens is indispensable parts.
Eyeglass is as the vitals in the camera lens, and the image quality of whole camera lens is played critical effect.Eyeglass is after moulding, grinding and polishing, and its optical axis tends to depart from its geometrical central axis, and this phenomenon is called off-centre.The off-centre of eyeglass can be divided into two kinds in theory, and a kind of is optical axis translation parallel with geometric center, and another kind is that optical axis intersects with the eyeglass geometric center, and the in fact normally combination of these two kinds of off-centre of the off-centre of eyeglass.
Traditional eccentricity of glasses lens measurement method has multiple, and wherein a kind of eccentricity of glasses lens measurement method at first adopts collimator to measure the first curvature center of eyeglass.Secondly, after the central axis of collimator rotates eyeglass, adopt again collimator to measure the torsion center of eyeglass, repeat above operation, thus the center of curvature of the eyeglass the when eyeglass of measuring is in diverse location with respect to collimator.After how much conversions, can obtain glasses lens eccentricity according to the eyeglass center of curvature of repeatedly rotating and measuring.Yet, rotate in the eyeglass process, may make the rotation axis of eyeglass depart from the central axis of collimator because the application of force is uneven, be not to obtain with same rotation axis thereby make the center of curvature of each measurement, thereby cause measurement result deviation to occur.
Summary of the invention
Therefore, be necessary to provide a kind of Accentric detector, to avoid the problem of rotation center skew, improve the measurement result accuracy rate.
Below will a kind of Accentric detector be described with embodiment.
A kind of Accentric detector, its it comprise coupling arrangement, eccentricity detecting device and bogey.This bogey is used for the carrying examined object.This coupling arrangement has relative first end and the second end.This first end is connected with the eccentricity detecting device, and this second end is connected with bogey.This first end and eccentricity detecting device be connected or in being connected of this second end and bogey at least one for being rotationally connected, so that eccentricity detecting device and bogey can relatively rotate around the central axis of coupling arrangement, thereby detect the examined object that is carried on bogey for the eccentricity detecting device.
Compared with prior art, this Accentric detector links to each other the eccentricity detecting device by coupling arrangement with bogey, when eccentricity detecting device and bogey are relatively rotated, remain take the central axis of coupling arrangement as rotation axis and rotate, avoid the offset problem of rotation axis in the rotary course, improve the measurement result accuracy rate.
