IPC: G03H1/22
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To effectively and spatially separate a light source from a light receiving means by using a polarizing hologram having a relatively small diffraction angle. SOLUTION: Luminous flux from a semiconductor laser 1, which is a light source, illuminate the recording surface of an optical recording medium 8 through a diffraction grating 3, the returned luminous flux reflected from a recording surface is received by a light receiving mean 9 through the diffraction grating 3 to conduct an information writing and/or reproducing. The diffraction grating 3 is a polarizing hologram having different diffraction depending on the polarization condition of the transmission luminous flux and is arranged to conduct a polarization operation to the returned luminous flux. A 1/4 wavelength plate 6 is provided on the optical path of the medium 8 side of the hologram to rotate the deflected surface of the returned luminous flux by approximately 90 degrees to the light beams from the light source.  A cube shaped optical element 2 is provided between the light source and the hologram so that the luminous flux from the light source 1 is totally reflected toward the hologram 3 and the diffracted returned luminous flux by the hologram are transmitted toward the means 9. The element 2 is made by combining two prisms 2a and 2b so that the tilted surfaces of the prisms are brought in close proximity to each other and the space between the tilted surfaces made by the prisms 2a and 2b becomes a region 2c having a low refractive index against the luminous flux from the light source 1.

Title: Optical encoder
Inventor: MURAKAMI HIROSHI
IPC: G01D5/245
Filed: 1995-01-30
Abstract: PURPOSE: To lower changes in duty ratio owing to changes in quantity of output light while preventing erroneous pulses as caused by the rotation of an encoder and the repetition of stopping by sampling the level of an biological signal during the zero-crossing of a differentiation signal obtained by time-based differentiation of the biological signal received by a photodetector. CONSTITUTION: After the time-based differentiation of a biological signal (a) received by a photo detector with a differentiation circuit 4, a wave form shaping is performed at a zero-crossing timing by a comparison section 5 to generate a signal (c). The signal (c) is free from the effect of changes in the duty attributed to changes in quantity of light of a light source during the rotation of an encoder but during the stoppage, a differentiation signal (b) is down to zero to cause an erroneous pulse. To solve this problem, the level of the biological signal (a) at the rising or falling edge of the signal (c) is monitored by a rising edge detection circuit 6, a sample holding circuit 8, a falling edge detection circuit 7 and a sample holding circuit 6.  The upper peak value and the lower peak value of the biological signal (a) are compared by making possible the discrimination of the rotation and stoppage of the encoder.
