Abstract: A measuring method for an optical element for obtaining a plurality of measurement errors of the optical element is disclosed, which comprises steps of irradiating a laser ray to an overall portion of the optical element, wherein the optical element is supported as one of a horizontal state and a vertical state; rotating continuously the optical element with 360 degrees to reflect the laser ray to obtain a reflected light wavefront picture from the reflected laser ray; analyzing the reflected light wavefront picture to obtain a plurality of aberration characteristics information, respectively, each being one of a sine and a cosine wave functions of a wavefront error for each of the plurality of specified rotation angles; analyzing a plurality of interference factors each for the plurality of measurement errors on each of the plurality of aberration characteristics information, respectively; calculating and extracting a plurality of classified aberration characteristics information for each of the plurality of specified rotation angles of the optical element from each of the plurality of aberration characteristics information according to the plurality of measurement errors, respectively; and analyzing each of the plurality of classified aberration characteristics information to obtain an error amount corresponding to each of the plurality of measurement errors, respectively.

Abstract: A gap compensation mechanism capable of self adaptive posture adjustment is disclosed, which comprises a base seat, having at least a fixation portion disposed thereon, the fixation portion having a flow path area disposed peripheral thereto; at least an adjustment unit, sleeved onto an outer rim of the fixation portion; and a filler, being filled within the flow path area. As such, a workpiece to be fixed may be disposed on a face of an adjustment unit. Further, the adjustment unit provides at least three freedoms for the altitude and two axial inclinations for self adaptively compensating a gap with any geometrical shapes and thus further adjusting the posture of the combined workpiece. After all the adjustments, a filler is filled to reinforce the structure and finally a fixation unit is employed for locking and fixing.
Abstract translation: 公开了一种能够进行自适应姿势调整的间隙补偿机构，其包括基座，至少具有固定部，所述固定部具有设置在其周围的流路区域; 至少一个调节单元，套在所述固定部分的外缘上; 和填充物，填充在流路区域内。 这样，待固定的工件可以设置在调整单元的表面上。 此外，调节单元为高度提供至少三个自由度和两个轴向倾斜度，以自适应地补偿具有任何几何形状的间隙，从而进一步调整组合的工件的姿态。 经过所有调整，填充填料以加固结构，最后采用固定单元进行锁定和固定。

Abstract: A projector having a first end and a second end opposite to the first end includes an image source, a mirror and a first lens set. The image source is disposed at the first end, and projects lights of an image along a first direction. The mirror is disposed at the second end along the first direction. The first lens set is disposed between the image source and the mirror, and forms for the lights a common aperture located between the first lens set and the mirror.
