摘要： An observation apparatus of the present comprises (i) a light source for generating light; (ii) a separating optical system which splits the light from the light source into two different polarized light beams; (iii) a condenser optical system which converges the two polarized light beams from the separating optical system so as to respectively form light spots on two different positions on a sample object; (iv) a polarization selecting means which has a predetermined analyzer angle and selects a specific polarized light component from composite light made of the two polarized light beams by way of the sample object; (v) light detecting means which detects the polarized light component selected by the polarization selecting means; and (vi) phase difference adjustment means which adjusts a phase difference between the two polarized light beams by way of the sample object and guides composite light composed of the two polarized light beams as circularly polarized light to the polarization selecting means, when the sample object does not modulate both phase and amplitude of the light incident thereon. Accordingly, this observation apparatus can detect a phase difference generated between the two light components respectively emitted from both side of a level difference on the sample object.

摘要： An optical waveguide device formed by a material showing anisotropy for refraction index and an optical instrument using the same device. The device comprises an electro-optic single crystal substrate on which are formed a first core portion higher in refractive index than the substrate with respect to both ordinary and extraordinary rays and a second core portion higher in refractive index than the substrate with respect to extraordinary rays pnly whereby the first core portion forms a single-moded waveguide for ordinary rays, and the overlapping region of the first and second core portions forms a double-moded waveguide for extraordinary rays. This optical waveguide device is used in place of a pinhole elementin an optical system of a confocal scanning optical microscopeso as to guide illuminating light to an object to be detected and to guide the reflected light from the object into a detector. This microscope includes a polarization conversion element for converting the polarizing direction of the illuminating light to one different from that of reflected light. The optical waveguide device functions as a single-moded waveguide for the illuminating light and as a double-moded waveguide for the reflected light.

摘要： A BPSK demodulator having a compound phase locked loop, such as a Costas loop, is disclosed. An in-phase component, signal SI from a Costas loop demodulating section 10 is converted by a symmetrical binary-valued signal forming converting circuit 21 into binary-valued signals, while a quadrature signal component SQ from the demodulating section 10 is also converted by a non-symmetrical binary-valued signal forming converting circuit 22 into binary-valued signals. The outputs of the circuits 21, 22 are supplied to a flip-flop 23 as its data input and its clock input, respectively. An output of flip-flop 23 is integrated by an integrating circuit 25. A CPU 28 decides whether or not an integrated value from integrating circuit 25 exceeds a predetermined threshold value TH to decide whether or not the Costas loop demodulating section 10 is in the locked state. In this manner, the locked state can be detected by a simplified constitution, while a pseudo-locked state may also be detected.
