Abstract: The invention relates to a method and to a device (1) for testing materials by determining and displaying as an image temperature differences above a threshold value on the surface of test objects (8). In a first step, a camera for determining and displaying as an image the temperature differences above a threshold value is used to determine the temperatures of object elements (22) within a test area (14) of the test object (8) facing the camera. The test area (14) is then provided with heat by means of a laser beam (4) in such a manner that the temperature of the surface of the test object (8) rises in the test area (14) by at least the amount of the threshold value. The object elements (22) are displayed as image elements in such a manner that the temperature differences above the threshold value between the object elements (22) are visible. The cool-down of the test area (14) is indicated by means of the image elements (20).

Abstract: The invention provides a method of sampling M sensors in a fiber optic detector array, by determining a maximum sampling rate possible, and assigning priority to each sensor. Thereafter, available sampling spots are divided into discrete blocks and the sensor of highest priority is assigned sampling slot(s). The remaining sensors are placed in the remaining sampling slots in order of priority, and if a sampling slot is taken, the remaining sensors are placed in the next closest slot. The invention also provides 1D and 2D digital and spatial wavelength domain systems including a plurality of fiber Bragg gratings (FBGs). The FBGs may be illuminated by a plurality of broad band light sources, and coupled thereto by 2null2 couplers. The systems may include a 1D or 2D wavelength dispersion device, and 1D or 2D optically sensitive solid state means for spatially separating the signals at each wavelength reflected by the FBGs.

Abstract: Optical touch switches are implemented based on the use of light total internal reflection and light scattering concepts. The optical touch switch basically consists of a light source, a light guide, a photodetector, and an electronic controller. The fingertip touching on the touching surface of the optical touch switch leads to the change in electrical current produced by the photodetector. As a result, the electronic control box senses this change of electrical current and allows the electrical load to stay at the desired state. Key advantages include ease of implementation, prevention of the light beam incident directly on the user's eyes, and ability to accept both strong and weak mechanical forces from users.

Abstract: Non-intrusive pressure sensors 14-18 for measuring unsteady pressures within a pipe 12 include an optical fiber 10 wrapped in coils 20-24 around the circumference of the pipe 12. The length or change in length of the coils 20-24 is indicative of the unsteady pressure in the pipe. Bragg gratings 310-324 impressed in the fiber 10 may be used having reflection wavelengths null that relate to the unsteady pressure in the pipe. One or more of sensors 14-18 may be axially distributed along the fiber 10 using wavelength division multiplexing and/or time division multiplexing.

Abstract: Systems and methods of measuring optical pulses are described. In one aspect, an optical pulse measurement system includes an optical signal divider and an optical signal conversion system. The optical signal divider has an optical input for receiving an input optical signal, multiple optical outputs, and a set of multiple optical channels. The optical channels are coupled between the optical input and respective optical outputs and are operable to delay propagation of optical signals, which are divided from the input optical signal, from the optical input to respective optical outputs by different respective amounts of time. The optical signal conversion system is coupled to the optical signal divider optical outputs and is operable to convert temporal intensity distributions of light received from the optical signal divider optical outputs into respective spatial intensity distributions in parallel.

The gas cell absorption lines are used to calibrate the Fabry-Perot etalon characteristics. Thus the device can be used to calibrate an optical instrument over a broad range of frequencies that are generated by the Fabry-Perot etalon with the accuracy determined by the stable gas absorption lines. A gas cell in combination with other frequency artifact generators such a Fiber-Bragg grating (30). The artifact generator has artifacts both within the gas cell spectrum as well as beyond. The transmission characteristics within the gas cell spectrum are used to calibrate the artifact at frequencies outside this range.
