IPC: G03F7/20
Filed: 1994-12-06
Abstract: PURPOSE:To miniaturize a beam splitter for optical path conversion while realizing a large numerical aperture and to attain a satisfactory image forming performance. CONSTITUTION:Illuminating light IL1 of linearly polarized light emitted from an object face 1 passes a first lens group G1 and is made incident on a polarizing beam splitter 2 formed to a rectangular parallelepiped. The length of the optical path from an exit/incidence face 5 of the polarizing beam splitter 2 to an exit face 6 is made shorter than that from the incidence face to the exit/ incidence face 6, and light made incident on a direction conversion face 4, a transmission part 3a, or a transmission part 5a goes to a concave mirror 9 through the exit/incidence face 5 and a quarter-wave plate 8. Illuminating light IL2 reflected by the concave mirror 9 is condensed on an image surface 10 through the quarter-wave plate 8, the direction conversion face 4, the exit face 6, and a second lens group G2. Transmission parts 3a and 5a are provided with thin films 7A and 7B which correct the phase deviation due to the direction conversion face 4.

Title: Measuring apparatus for electromagnetic field strength
Inventor: ITO HIROSHI
IPC: G01R29/08
Filed: 1990-11-06
Abstract: PURPOSE:To enable accurate measurement of an electromagnetic field strength without being affected by disturbance, by detecting as a beat signal a frequency difference between first and second polarization components which are different slightly in a light frequency. CONSTITUTION:A sensor element 50 is set in an electromagnetic field measuring field 100, while a measuring light generating element 70 and an electromagnetic field strength measuring circuit 90 are set outside the measuring field 100. A waveguide 56 for a measuring light propagates one of first and second polarization components of an introduced measuring light 200 in a TE mode and the other in a TM mode, and makes them pass through a phase modulating element 58 of the sensor element 50 in the course of propagation. A phase difference corresponding to an electromagnetic field strength occurs between the polarization components propagated through this modulating element 58 in the respective modes thereof. The measuring light 200 passing through the modulating element 58 is received as an input by a beat signal detecting element of the circuit 90 through a polarization plane maintaining optical fiber 68, and it subjects the first and second polarization components to square detection and outputs a frequency difference between the two polarization components as a beat signal. Based on this beat signal, an arithmetic element detects a phase difference between the polarization components and computes the electromagnetic field strength.

Title: Optical head device and optical device
Inventor: YAMAMOTO HIROAKI
IPC: G11B7/135
Filed: 1992-11-12
Abstract: PURPOSE:To reduce the number of head amplifiers for signal detection and to eliminate unbalance in a magneto-optical signal head amplifier. CONSTITUTION:Light emitted from a semiconductor laser 101 is converged and reflected on an optical disk 105, and is converted to focusing light by a detection lens 104 via a beam splitter 106. Furthermore, the light is divided into two optical paths by a beam division element 10. Then, the light is made incident on a polarization separation hologram 121, and is polarized and separated to diffracted light and transmission light. Those light are detected by a photodetector 195 divided into plural areas. Since the transmission light is used for the detection of a tracking error signal, and the diffracted light for a focusing error signal, the unbalance in the head amplifier can be prevented from being generated in the reproduction of a magneto-optical signal. Also, the number of head amplifiers can be reduced without necessitating single head amplifier for the detection of the magneto-optical signal.
