    Abstract: Изобретение относится к контрольно-измерительной технике и используется при измерении деформаций (напряжений) в различных конструкциях. Фотоупругий элемент имеет в плане крестообразную форму. Фронтальные поверхности элемента параллельны направлению прилагаемых усилий и являются оптически плоскими. Боковые поверхности имеют постоянный или переменный радиус кривизны. При приложении измеряемой нагрузки вдоль одной из его осей возникают дополнительные напряжения в центральной части элемента и как следствие дополнительная разность фаз между взаимно перпендикулярными компонентами поляризации луча, прошедшего сквозь фотоупругий элемент, что приводит к повышению чувствительности фотоупругого элемента к нагрузкам.

    Abstract: A method and apparatus for measuring strain on a surface of a substrate (140) utilizes a substrate surface coated with at least one coating layer (145). The coating layer (145) provides both luminescence and photoelasticity. The coating layer (145) is illuminated with excitation light (110), wherein longer wavelength light is emitted having a polarization dependent upon stress or strain in the coating. At least one characteristic of the emitted light is measured, and strain (if present) on the substrate (140) is determined from the measured characteristic.

    Abstract: A cladded birefringent pressure sensor for use in a pressure-sensing system. The sensor is a single composite plate consisting of two plates (122, 124) each with different indices of refraction. One surface of the sensor is exposed to the environmental pressure under measurement. A collimated broad band light source is transmitted via a fiber optic cable, a polarizer and a birefringent bias element which transmits a wavelength/polarization component of light through the sensor. An external force applied to the sensor adds a stress-induced component to the polarized lightwave. The lightwave exits the sensor and is captured by a second polarizer producing a modulated light spectrum. A focusing element collects the light and transmits it down another fiber optic cable. The cable transmits the light to an opto-electronic interface where the fringe pattern is extracted and a computer compatible signal is generated for a CPU. The CPU performs a Fourier transform on the fringe pattern, where the phase term for a selected frequency is the measure of the externally applied pressure on the sensor.

    Abstract: The invention provides a load measuring apparatus for weighing vehicles. The cell is in the form of a plate structure which is of such small thickness that the vehicle wheel can be driven onto the plate structure without the use of a ramp. The plate structure comprises or embodies light transmitting material, a polarised light source which sends a beam of polarised light through the light transmitter material in a direction in the plane of the plate structure, and a polarizer and photodetector are located to detect the light beam emerging from the plate, the intensity of the emerging beam being an indication of the compressive weight or load on the plate. A plurality of the plate structures are used for the respective wheels of the vehicle and an electronic processor is used to provide indications of the loads on the cells to give total vehicle weight.

    Abstract: It is possible to reduce the time required for calculating a force vector by using a force vector reconstruction method using an optical tactile sensor. The method includes: a step for imaging behavior of a colored marker when an object is brought into contact with a contact surface of an elastic body; a step for acquiring, from the marker image, information on behavior of a number of markers greater than the number of force vectors to be obtained; and a step for inputting the information on the behavior of the acquired markers to a transmission function and outputting a force vector. The force vector is calculated by using only the information on the behavior of markers of an area A1 in the vicinity of the position P at which the force vector is to be obtained.
