摘要

In order to obtain high accuracy of wavelength measurement in automatic scanning monochromator, some improvements are taken in the computerized data processing. First, to get high signal to noise ratio, the sampling in full period is used at the digital conversion of optical intensity signal, which increases the correctness of peak judgment of spectral line. And then, to get low wavelength scale bias, the calibration with sine model function is used in the calculation of wavelength from step count, in which the parameter of the equation is determined with least squares method to make the residual minimum. Finally, it is proved in the experiment that this instrument has high accuracy of wavelength measurement with more repeatability and less bias.

Nails are the body part which are farthest from the heart and therefore receive oxygen at last. As a result the nails are the first who show the symptoms of a disease in the human body. Fingernails can be easily captured for diagnosis and there are no heavy equipment or no specific conditions required to use nail image for disease diagnosis, like in other tests and scanning processes. Human nails deliver beneficial information about complaints or any nutritive imbalances in the human body depending upon their shape, texture and colour. In human beings, numerous systemic and skin diseases can be easily analyzed through careful examination of nails of both the limbs. A lot of nail illnesses have been found to be primary signs of numerous underlying systemic illnesses. The colour, texture or shape changes in nails are signs of many diseases mainly affecting nails. Considering all these properties of nails a system is proposed that uses digital image processing (DIP) methods for identifying such changes in the human nail to get more precise results and predict numerous diseases effortlessly. With the emerging Internet of Things (IOT) concept the generated report is made available remotely, this will help users to reduce transportation efforts. As the system has to deal with large and private data, the security of data must be ensured. To keep the data confidential, the Blockchain concept which is one of the most emerging concepts in the field of data management is used. The paper contains the implementation of the digital image processing for feature extraction of nail images, usage of IOT (ThingSpeak cloud) for data storage and implementation of Blockchain to keep the system secured and theft free.
