摘要

微中子望遠鏡是用於偵測濤子微中子，由光學系統與電子讀出系統構成，光學系統包含透鏡與凹面鏡，我們借助平行光去量測
面鏡的成像大小。因此，我們設計名為線性導軌的機器，它能在空間中控制雷射光源的位置，以便於模擬平行光。

當線性導軌平移雷射光源，有一些因素使得光源無法保持相同的指向。所以，我們增加監控裝置以便於觀測這種微小的方向偏差，
然後修正雷射光源的座標。此外，也展示使用攝像機進行雷射光點位置的讀取。

Neutrino telescope (NuTel) is used to detect tau neutrino. It is composed of optics system and
electronics readout system. The optics system is composed of a lens and a concave mirror. We need
parallel light to measure image size through mirror. Therefore, we design a machine which is named as
Linear Guide. It can control the position of a laser source to simulate parallel light.

When Linear Guide move the laser source, the direction of laser beam can not keep the same resulted
from some factors. So, we add a monitor device to observe the tiny orientation bias, and then calibrate
the coordinate of laser source. Besides, we use camera to readout the spot position.
