Patent number: 8985846Abstract: A laser power meter incorporating an absorber disc with a peripheral thermopile ring, either continuous or segmented, and an additional temperature detection element in the central portion, that enables measurement of beam size. This detection element can be a thermopile element, generally a ring of smaller diameter than the peripheral thermopile used, and located closer to the center of the absorber disc. With this arrangement the beam size can be measured, in addition to measurements of the power and the position of the beam. Alternatively, this centralized detection element can be a single thermocouple junction located at the center of the disc, which acts as the hot junction of a thermocouple pair. The second or cold junction is effectively located on the disc close to the peripheral thermopile. Alternatively, two temperature measuring elements can be used, one at the disc center and one at the periphery.Type: GrantFiled: June 10, 2010Date of Patent: March 24, 2015Assignee: Ophir Optronics Solutions Ltd.Inventors: Eliyahu Bender, Shimon Elstein, Mark Ivker

Publication number: 20150053847Abstract: One embodiment of the disclosure includes an A-D conversion circuit connected to a photodiode for providing a silicon photomultiplier that with enhanced detection accuracy and a time resolution. A current generated upon photon detection by the photodiode partially flows into another photodiode adjacent to the photodiode arranged in parallel via a resistor. At this time, the current is charged into a parasitic capacitance adjacent to the photodiode, and thereafter is discharged. However, the discharged current cannot flow toward an output terminal by the A-D conversion circuit, and also cannot switch the A-D conversion circuit. Consequently, the construction of the disclosure can detect light with no influence of the current discharged from the parasitic capacitance. As a result, the disclosure achieves a silicon photomultiplier with high detection accuracy and a satisfactory time resolution.Type: ApplicationFiled: March 29, 2012Publication date: February 26, 2015Applicant: SHIMADZU CORPORATIONInventor: Tetsuo Furumiya
