A thermal lens forming element includes a first chamber serving as a control light absorbing region, which is configured as a columnar body or an N prismatic body (wherein N is an integer equal to or greater than 4) circumscribing the columnar body and filled with a control light absorbing dyestuff solution containing a solvent having a viscosity of 0 to 3 mPa·s at 160° C. or above and a ratio of the viscosity of the solvent at 160° C. to a viscosity of the solvent at 40° C. not less than 1 and not greater than 6, wherein the columnar body or the N prismatic body circumscribing the columnar body has a central axis coinciding with an optical axis of incident signal light. The first chamber is connected to a second chamber via a solution channel and a dam. The dyestuff solution and a bubble of an inert gas are confined in the second chamber.

An optical deflection apparatus includes a signal light source configured to emit signal light having one or more wavelengths, a control light source configured to emit control light having a wavelength different from the wavelength of the signal light, a thermal lens forming optical element including a light absorption layer configured to transmit the signal light and selectively absorb the control light, and a beam-condensing unit configured to cause beam-condensation of the control light and the signal light at different convergence points in the light absorption layer. The thermal lens forming optical element causes convergence and divergence of the control light and the signal light on an incidence plane of the light absorption layer or its vicinity in a light traveling direction, wherein a thermal lens is reversibly formed in the light absorption layer due to a temperature increase occurring in a region where the control light is absorbed and its peripheral region, and the thermal lens changes a refractive index to change a traveling direction of the signal light.
摘要:
An automatic circulation collection type data system is constructed by connecting a monitoring device and data collecting modules disposed at respective places through optical cables. The monitoring device transmits a trigger pulse for data collection through the optical cable to each data collecting module. An identification code is given to each data collecting module, and each data collecting module has an automatic circulation mechanism comprising first and second optical switches, a data collecting unit, and a controller 6 for performing various kinds of control for data collection. When receiving the trigger pulse from the monitoring device, the automatic circulation mechanism turns on the third switch and transmits the collected data through the optical cable to the monitoring device together with the identification code, and also transmits a trigger pulse through the optical cable to a next data collecting module.
