    Abstract: 一种将斩光器应用于光致发光测量的方法,可以用于延迟发光的测量,测量中有两条光路:光路一是激发光照射样品的光路;光路二是探测器探测样品发光的光路;该方法利用反光镜或者棱镜将其中一条或者两条光路反射或折射,使两条光路都通过同一个斩光器。这样就实现了同一个斩光器在测量中同时对激发光和被测样品的发光进行斩光,因而可以探测样品的延迟发光和激发态寿命。该方法可以用于光谱仪和荧光成像装置,并可以搭配任意的稳态光源使用,且无需再配备脉冲发生器、延迟发生器和快门附件等,简化了仪器装置并降低了成本。该方法也可以搭配大功率的近红外激光器,用于上转化材料或近红外发射材料的时间分辨的成像。

    Abstract: The present disclosure concerns an apparatus (10) and method for reading out an optical chip (20). A light source (13) is arranged for emitting single mode source light (S1) from its emitter surface (A1) towards an optical input (21) of the optical chip (20). A light detector (14) is arranged for receiving measurement light (S2) impinging onto its receiver surface (A2) from an optical output (22) of the optical chip (20), and measuring said received measurement light (S2). The emitted source light (S1) is aligned to enter the optical input (21) of the optical chip (20) and the measurement light (S2) is aligned back onto the receiver surface (A2). The receiver surface (A2) is larger than the emitter surface (A1) for facilitating the overall alignment.

    Abstract: A device (1) for inspecting objects with a substantially spherical surface, such as for example eggs or fruit, comprises optical observation means (8) for observing the objects. The device has a supporting surface (10) for supporting the objects. There is a light source for illuminating the objects. The device also comprises a box (2) with reflective walls (3a, 4b and 4a shown) which is positioned above the supporting surface (11). The light source and the observation means (8) are accomadated in the box (2). A plurality of objects can be placed next to one another on the supporting surface (10) and can be illuminated equally well.
