“…In recent years, the LED has been widely applied because of its small volume, low energy consumption, long life, high brightness, environmental protection etc in the indoor and outdoor lighting, but because of LED light source with high directivity and high color temperature, easy to produce the glare, easy to cause the human eye light damage, thus limit its actual application [1]. In order to realize the light uniformity and high efficiency, the light diffusion plate is widely used in LED lighting [2][3][4], its main function is to transfer the point and the line source into the line and the surface light source, which gets beam shaping and make the intensity of incident beam uniform distribution. But it requires the diffuser must have high light transmittance, in order to reduce the loss of light energy.…”

In the paper, the transmission process of light in the light diffuser plate of micro V-cut prism structure was analyzed and the uniformity and transmittance of the diffuser were calculated based on Light Tools software; At the same time, the effect of micro V-cut prism structure, namely the height of the prismthe width of the prismthe aspect ratio of the prism and the arrangement of the prism on the uniformity and transmittance of the diffuser were simulated. The result shows that the light diffuser plate of micro V-cut prism structure has effective diffusion on the LED daylight lamp which integrated optical property of the uniformity and transmittance is more than 85%; Furthermore, the aspect ratio of the prism has a big influence on the optical property of the diffuser, it shows that the integrated optical property of the diffuser is best when the aspect ratio is 1.2.

Spectral imaging is performed primarily using reflective devices, but for transparent objects, especially transparent liquids, a transmission-based device is required to obtain more effective spectral imaging data. For this purpose, a transmitted spectral imaging data acquisition device based on a miniature multispectral spectrometer was developed and demonstrated its capability in the analysis of transparent liquids. This device allows rapid and noncontact acquisition of spectral imaging signals from transparent liquid samples. The design of the device mainly includes two parts: a shooting system and a master computer, and the optical path is optimized by selecting the appropriate diffusion plate. As an application example, a concentration-absorbance model of liquid samples at characteristic wavelengths was established and used to predict the concentrations of different liquid samples. Experimental results showed that the relative error of the predicted concentration values was within 4%, indicating excellent detection performance. Therefore, the design of the device demonstrates favorable feasibility and wide applicability in liquid detection systems.
