Filed: 1978-07-17
Abstract: PURPOSE: To increase the dynamic range as well as to prevent the lowering of the signal quality by carrying out instantaneously both compression and expansion of the amplitude for the audio signals in accordance with the signal level.  
     CONSTITUTION: The audio signals sent from input terminal of amplitude compressor A are applied to output terminal 2 via amplitude compression circuit 3, and at the same time part of the audio signals is applied to FM modulation circuit 5 to have the FM modulation. The FM-modulated signal is applied to BPF6. And in case the modulated signal features a larger band width of BPF6, the output with AM modulation applied by slope of the filter characteristics is generated at the output of BPF6. This output is detected through detection circuit 7, and the signal of the positive pole area of the output signal is applied as the control voltage of circuit 3. Thus the compression is performed in accordance with the signal level. On the other hand, amplitude expander B has the same operation as compressor 1 via FM modulation circuit 5', BPF6' and detection circuit 7' in order to expand the signal level for expander B.

Abstract: PURPOSE:To detect movements in a fundus part with good accuracy so that eyeball motions are automatically followed up by discriminating travel speeds of blood cells in the fundus part by using speckle signals so as to identify a blood vessel part in the fundus part, by controlling points of illumination and observation of a laser light in accordance with the travel of the blood vessel part, if it moves, and thus following up the blood vessel part automatically. CONSTITUTION:A laser light is made to arrive at a fundus 16b of a subject eye 16 through relay lenses 12, 13, a perforated mirror 14, an objective lens 15 and a cornea 16a along an optical path, through which lights for fundus observation and photography are injected into the fundus, and is made to illuminate a blood vessel to be measured and followed up. A movable mirror 8 makes a position of beam spot on the fundus 16b of the subject 16 movable and its control is carried out by operating, for example, a track ball 17 through an output part 46 before the measurement is started. The movable mirror 8 is controlled in such a manner that tilting angles of the mirror with the optical axis in X and Y directions are made changeable independently. As the movable mirror 8 is set almost at a conjugate position with the cornea 16a or pupil of the subject eye 16, it is possible to move the beam on the fundus without largely changing an incident position of the laser beam on the cornea of the subject eye 16.
