IPC: H01S3/213
Filed: 1994-08-31
Abstract: PURPOSE: To enable the improvement of excitation efficiency of dye solution even if its concentration is reduced to allow exciting light to be partly transmitted, by placing the reflection mirrors and cylindrical lenses of a pair of focusing optical systems conjugately with respect to a flow cell. CONSTITUTION: Exciting light P, let in at either of a first and a second focusing optical systems 12A, 12B, is focused and shaped into a rectangle of DXL on a flow cell 11 shaped through an incident window 13a. The component that passes through the flow cell 11 is shaped into DXL by the other focusing optical system, and forms an image on the flow cell 11. In other words, the cylindrical lenses 16 and the reflection mirrors 12 of the focusing optical systems 12A, 12B are conjugately positioned with respect to the flow cell 11. Thus exciting light P that first irradiates the flow cell 11 and exciting light P that, after passing through the flow cell 11, irradiate it again, are identical with each other in Y-position when they irradiate the flow cell 11. This improves excitation efficiency.

Filed: 1991-07-24
Abstract: PURPOSE:To decrease the dispersion in the manufacture of phase noise cancellers applied as a patent whose application number is 265585 in 1990 with a phase matching phase shifter and to reduce phase noise more by using an optical signal. CONSTITUTION:A signal outputted from a signal source 1 is bisected and imparted to a delay line 2 and a mixer 3. The delay line 2 acts like delaying an imparted signal by a predetermined time. The signal delayed by the delay line 2 is subjected to phase change with a phase shifter 5.

The phase change in the phase shifter 5 is decided so that the phase of the original signal and the phase of the signal outputted from the phase shifter 5 are in-phase. Thus, the phase noise component having a frequency being a period of the integer multiple of the delay time is cancelled.
