Inventor: HIRONISHI KAZUO
IPC: H04B10/60
Filed: 1990-08-27
Abstract: PURPOSE:To know the modulation factor of intensity modulation by converting optically modulated light into an electric signal by a photodetector which has a narrower photodetection range than the modulation range of the optical modulation and finding the time mean ratio of the DC and AC components of the electric signal. CONSTITUTION:This transmitter receiver is equipped with light source 2, an optical modulator 4 which imposes intensity modulation upon light from the light source, a bias circuit 6 which applies a bias voltage to the optical modulator, an optical branching circuit 10 which branches light from the optical modulator, the photodetector 12 which converts one light beam branched by the optical branching circuit photoelectrically, a DC level detecting circuit 14, an AC level detecting circuit 16, etc. The optically modulated light is converted into the electric signal by the photodetector 12 which has the narrower photodetection sensitivity range than the modulation band of the optical modulation, the DC and AC components of the electric signal are separated and detected, and the time mean ratio of the DC and AC components is found to monitor the modulation factor of the optical modulation. Further, the bias voltage applied to the optical modulator is so controlled that the time mean ratio of the DC and AC components becomes constant, thereby stabilizing the modulation factor.

Title: Camera
Inventor: SHIBAYAMA YOSHINOBU
IPC: G03B1/00
Filed: 1986-09-20
Abstract: PURPOSE:To perform more accurate detection with simple structure and at low cost by arranging both a light emitting element and a light receiving element on the same surface side with a film and providing a light guide opposite to both elements across the film surface as a detecting means which uses both elements and detects the leader part of the film. CONSTITUTION:When a rear cover 19 is closed, a lock mechanism locks the rear cover 19 and the film F advances toward a film entry path 18 temporarily and is wound in a cartridge P. In a camera, on the other hand, light projected by the light emitting element 4 is cut off the film F and never reaches the light guide 5, so the light receiving element 6 judges that the film F is passing over the light emitting element 4. When the film F further moves and one of perforations F1 is positioned on the light emitting element 4, the light from the light emitting element 4 passes through the perforation F1 and is reflected by a 1st reflecting surface 5a to pass through the light guide 5. Then, the light is changed in direction to the film F side by a 2nd reflecting surface 5b, but the light is cut off the film F again and never reaches the light receiving element 6. Consequently, the leading part of the film is accurately detected with simple structure and at low cost.
