The invention relates to optical microscopy, in particular to methods for photothermal examination of absorbent microinhomogeneities using laser radiation sources and can be widely used in laser engineering, industry and biomedicine for examining relatively transparent objects containing submicron impurities, including the detection of local inclusions and defects in ultrapure optical and semiconductor materials and the non-destructive diagnosis of biological samples on a cellular and subcellular level. The aim of the invention is to increase the sensitivity, spatial resolution and informativity of examination of local absorbent microinhomogeinities in transparent objects and to measure said microinhomogeinities even when they are less than the used emission wavelength. The inventive method consists in radiating a sample with a pumping laser beam. The duration of the radiation is equal to or less than a representative time for cooling the examined microinhomogeinity. The relatively large surface of the sample is radiated, the shape thereof being greater than the wavelength of the used pumping laser. Thermal variations of the refractive index occurring in the sample as a result of absorption produced with the aid of the pumping beam are recorded by measuring parameters of a test laser beam. The diameter of the test beam is chosen in such a way that it is equal to or greater than the diameter of the pumping beam. A diffraction-limited phase distribution along the cross-section of the testing laser beam is transformed into an amplitude image, the microinhomogeinity properties being determined by measuring said amplitude image.

The invention relates to optical microscopy, and more particularly to the methods for photothermal examination of absorbing microheterogeneities using laser radiation. The invention can be widely used in laser technique, industry, and biomedicine to examine transparent objects with absorbing submicron fragments, including detection of local impurities and defects in super-pure optical and semiconducting materials and non-destructive diagnostics of biological samples on cellular and subcellular levels.The object of the present invention is to increase sensitivity, spatial resolution and informative worth when examining local absorbing heterogeneities in transparent objects, as well as to detect the size of said heterogeneities even if said size is smaller than the radiation wavelength used.Said object is achieved by the pump beam irradiation of a sample, the duration of said irradiation not being longer than the characteristic time of cooling of the microheterogeneity observed. A relatively vast surface of the sample is irradiated at once, the size of said surface not being larger than the wavelength of the pump laser used. The refraction index thermal variations, induced by the pump beam in the sample and being the result of absorption, are registered by the parameter change of the probe laser beam. A chosen probe beam diameter should not be smaller than the pump beam diameter. The diffraction-limited phase distribution over the probe laser beam cross-section is transformed to an amplitude image using a phase contrast method. The properties of microheterogeneities are estimated by measuring said amplitude image.

One object of the present invention is to monitor water pipes regularly and to detect water leaks by using basic equipment and to provide a device that generates an alarm when a leak occurs. The present invention responds not only to minor leaks that occur naturally because, for instance, a water pipe is decrepit, but also responds to human-caused leaks, such as those that occur because a person forgets to turn off a water faucet or because of the failure of equipment such as a hot-water heater. The present invention is a leak-detection alarm system that is composed of two main parts: (1) a leak-detecting check valve that detects movements of a movable device that makes the same movement as the valve element of a check valve that is attached to a water pipe and performs switching, and that transmits as detection signals the movement of valve elements, and (2) a signal-processing device that analyzes detection signals transmitted by the leak-detecting check valve and actuates a leak-detection alarm. The leak-detecting check valve has a main valve and an ancillary valve. The main valve operates in response to a high rate of flow of fluid through the pipe, such as occurs when there is a large leak that corresponds to said human-cause leaks, and the ancillary valve operates in response to low rate of flow of fluid through a pipe, such as occurs when there is a small leak that occurs naturally.
