Study On Characteristics Of NVIS Components

NVIS:It is the acronym for night vision imaging system. The flat panel display components of night vision imaging system are used to display components. That is, we know LED. This thesis focuses on the LED module to measure, after the conclusion, discuss its consistency.Since different LED applications, it will be encapsulated with different lens. The light intensity distribution is also different, so the LED test should not use the brightness units to measure in the experiment. Parameters of the test light only on the luminous flux, luminous intensity, light intensity distribution, spectral power distribution, color and other important parameters. LED color is also one of important physical parameters. We can use advanced optical technology shoot the international spectrum in which LED's color test and the spectral color measurement.After the test of LED, according to the experimental curves obtained by optical properties of LED, research on the consistency of LED, hope that the process of analysis, conducted on a horizontal contrast LED, distinguish between the merits of LED, and on this basis, I can do some adjustment with the characteristics of NVIS display, thereby improving the overall level of the device.In this experiment, we will learn all principles of LED and Build a test platform about NVIS flat light emitting device, and do some test about LED. We use the computer to process data and analysis of the data, eventually find the best answer.
