Using the tightly focused visible light (wavelength λ=488nm) illuminating, the ferroelectric domain patterns of the undoped lithium niobate crystal have been demonstrated. The influence of the visible light intensity on the domain nucleation field was investigated. The reduction of nucleation field decreases exponentially with increasing incident irradiation intensity. Once a domain is nucleated it can be dictated by the far-field light diffraction patterns. An assumption is proposed that the reduction of nucleation field is directly related to the defects mobility and structure of the crystals.

So2 Concentration

SO2 is one of the most important atmosphere pollutants which can be figured out by measuring the attenuation of the visible light intensity on the characteristic wavelength. But the visible light intensity is also attenuated by the monodispersion soot particles because of the particles absorption and scattering. The interference of the monodispersion particles is discussed in the paper. Simulation results show that the impact parameters on the SO2 concentration accuracy include the received scattering angle range, particle size and concentration. According to the study SO2 concentration measurement accuracy can be improved

Incoming Radiation

This paper examines the photosynthetic response of single attached leaves (of four different species) to an increasing angle of incidence (8) of incoming radiation. The intensity of light falling upon a leaf can be deduced from geometrical optics to be proportional to cos 8. The results reported here suggest that the photosynthetic. activity of leaves exposed to a limiting light intensity follows a similar relationship. Explanations of this empirically determined relationship are discussed.
