The invention relates to an optical module 1, in particular for a motor vehicle, intended to emit a light beam along a longitudinal optical axis A comprising: at least one first light source producing a first function and at least one second light source performing a second function; a light...
We introduce a photochemical bond forming system, where two colours of light are required to trigger covalent bond formation. Specifically, we exploit a visible light cis/trans isomerization of chlorinated azobenzene, which can only undergo reaction with a photochemically generated ketene in its cis ...
second group of second light sources (2), the light sources (1, 2) of the two groups being at least partly allocated different lighting functions and the region (3) formed by the first light sources (1) is completely enclosed by the region (4) formed by the second light sources (2)....
All light sources operated in the continuous-wave mode without any optical choppers. Dependence of up-converted characteristics of (b) the short-circuit current (ΔJsc) and (c) open-circuit voltage (ΔVoc) on the 1,300 nm LD excitation power. The solid lines indicate fitted curves ...
Figure 1. A simple circuit that measures relative light densities. Note that in this circuit, there are two special resistors, R1 and R2. R1 (LDR1) measures the brightness of the two light sources. What is an LDR? The term stands for light dependent resistor or photoresistor. It is a...
We investigate and propose a method for assessment of the illumination condition covering two light sources. The method may be of some support for color vision and multispectral analysis methods that rely on a specific illumination condition. It is constrained to classifying the illumination condition ...
Question: A plastic surgeon is using two light sources: a headlamp that emits a beam of visible light and a handheld laser that emits infrared light. For which source are the photons more energetic? A plastic surgeon is using two light sources: a...
There are two types of participle in English: the past participle and the present participle. 英语中有两类分词: 过去分词和现在分词. 《简明英汉词典》 May the friendship between the peoples of ( our ) two countries last forever. 祝两国人民的友谊万古长青. 《现代汉英综合大词典》 There is keen...
There are at least two light sources one of which operates with the train movement in one direction and the other can be switched on during movement in the opposite direction. One light source has at least one forked light lead with one end facing the light source and with two free ends ...
A lighting unit for a motor vehicle comprises at least two light sources (1,2) with sheets (6) between the light sources inside the beam (L1,L2) so directed that light from at least one light source (2) hits the sheet surfaces and at least part of the light from the other light so...
