6. The problem state.

Improvement of agricultural production quality is one of prominent direction promoting the development of the agrarian sector of economy and agro-food systems. This direction is inseparably linked with solving of problems for evaluation of characteristics of farm products that include fruits, vegetables and meat foods to define optimal harvesting, preserving and processing conditions and terms. There is a number of biotechnological methods, namely sensory evaluation, which gives only qualitative results, and various mechanical tests (punch, pressure tests and so on), which are characterized by destruction during study process, and thus are undoubtedly imperfect. On the other hand, nondestructive optical-digital techniques based on analysis of biospeckle patterns by using spatial-temporal speckle correlation have developed successfully. Our department as one of the first among research groups has started to deal with a problem of use of spatial-temporal speckle correlation techniques to study the cellular activity of biotissues (see Refs. in Section 5).  In particular, mechanisms of temporal changes of biospeckle spatial distributions displaying cellular activity of fruit and vegetable tissues by using spatial-temporal speckle correlation technique were established. Studying of these mechanisms allows elaborating the methods for estimation of apples, tomatos and other fruit and vegetable freshness and shelf life (see Refs. ). Besides, researches of meat food for operational assessment of structural changes in muscle tissues after slaughtering by using optical-digital correlation methods were also fulfilled . Now we start to develop new techniques based on digital speckle pattern interferometry for detection and localization of different defects and physiologic disorders in fruits and vegetables during their harvesting, storage and processing. This direction is also very challenging, because a lot of data about cellular processes and their spatial-temporal disturbances in studied biological objects is accumulated in temporal series of biospeckle fringe patterns.
