強(qiáng)力激光成防御小行星有利武器
Arcoptix公司推出的基于偏振光學(xué)的具有光子級(jí)別高靈敏度的微型光譜儀，其靈敏度比常用的光柵式光譜儀高出100倍。探測(cè)器靈敏度可達(dá)15光子/count, 噪聲可低至0.02count.此種設(shè)計(jì)特別適用于低光照光譜的研究。包括混濁液的光譜測(cè)試，漫反射光譜測(cè)試，熒光光譜測(cè)試。The ARCspectro HT-2D is an ultra compact stationary Fourier transform spectrometer. Based on polarization optics it provides an extremely high sensitivity and is ideal for measurements of low light and diffusing sources （diffuse reflection and turbid media）. Its unique design permits to collect light over a large angles and it has an high entrance surface of several millimeters. The operation principle prevents from problems like drift or dark noise which allows high contrasts at single shot measurements. Thanks to its 2D camera it averages over 1000 measurements in one shot! It can be used in extremely simple optical setups, no need for focusing optics. The user can directly illuminate the entrance opening with the light to be spectrally analyzed or can bring the light to the system with fiber bundles.
