Description

雷射微型投影機 Laser micro projector

本發明係關於一種雷射微型投影機,尤指一種具有多重投影與立體顯示功能之雷射微型投影機。 The invention relates to a laser micro projector, in particular to a laser micro projector with multiple projection and stereo display functions.

一般習知之投影機只能具有單一投影功能,因此其所投影出來之影像只有單一畫面,如要具有多重投影功能的話則需要利用多個光學鏡片來加以分光以達到多重投影之功能,如申請專利號201234097『具雙投影功能之投影機』中所揭露的,利用兩分光鏡片加以組合以達到雙重投影之目的,但是在組合該兩分光鏡片時,對於組裝之精準度有其困難所在。 Conventional projectors can only have a single projection function, so the projected image has only a single image. If multiple projection functions are required, multiple optical lenses are needed to split the light to achieve multiple projection functions, such as patent application. No. 201234097 "Projector with Dual Projection", which uses two spectroscopic lenses to combine to achieve dual projection, but when combining the two spectroscopic lenses, there is difficulty in assembly accuracy.

另外如要達到具有立體顯示功能的話則需要有兩組光源模組,分別對於上述之兩組光源進行偏極化才能達到立體投影之效果,其成本相對偏高,同時對於雷射微型投影機之體積就無法縮小,而達到輕量化之要求。 In addition, if you want to achieve the stereo display function, you need to have two sets of light source modules. The two sets of light sources can be polarized to achieve the effect of stereoscopic projection. The cost is relatively high, and at the same time, for the laser micro projector. The volume cannot be reduced, and the requirement for weight reduction is achieved.

另外為偵測雷射光源的衰減程度,通常為多增設一雷射光源或是使用分光稜鏡分光,使該光源照射於光偵檢器上,而如果使用增加雷射光源則會造成成本增加與投影機體積不易小型化的缺失;若是使用分光稜鏡來進行分光,則無法控制分光量大小,容易造成影像品質低落的缺失。 In addition, in order to detect the attenuation degree of the laser light source, usually a laser light source is added or a split light beam is used to make the light source illuminate the light detector, and if the laser light source is used, the cost is increased. It is not easy to miniaturize the size of the projector; if the splitter is used for splitting, the amount of light splitting cannot be controlled, which is likely to cause a lack of image quality.

本發明人為改善上述之缺失,提出利用一分光鏡片來達到分光的功能,藉由該分光鏡片的設計,可以達到控制分光量大小的效果,改善因利用分光稜鏡而無法控制分光量所造成之影像品質 不佳與需增加一額外雷射光源鎖增加之成本。 In order to improve the above-mentioned defects, the inventors have proposed to use a spectroscopic lens to achieve the function of splitting light. By designing the spectroscopic lens, the effect of controlling the amount of spectroscopic amount can be achieved, and the amount of splitting light cannot be controlled by using the spectroscopic diaphragm. Image quality Poor and the need to add an additional laser source lock to increase the cost.

本發明更提供一種利用分光鏡片來達成雙投影之功能,改善上述之需利用多個分光鏡來達成雙投影之分光鏡組裝不易之缺失;本發明更提供一種利用分光鏡片將雷射光束分光後再加以偏極化,以改善立體投影需用雙投影光機所形成之成本偏高與無法縮小投影機體積之缺失。 The present invention further provides a function of using a spectroscopic lens to achieve dual projection, and improving the above-mentioned need to use a plurality of spectroscopes to achieve a double projection of the spectroscope assembly is not easy to be missing; the present invention further provides a spectroscopic lens for splitting the laser beam The polarization is further increased to improve the cost of the stereo projection required by the dual projection machine and the lack of the projector volume.
