Abstract: A device for controlling an amount of light of a lighting unit for use in an endoscope, used to view an image of an object. The device includes a light shield for shielding light generated by a light source and transmitted to the endoscope. A stepping motor drives the light shield for a series of predetermined time intervals. Brightness of the image is detected during each of the time intervals and a predetermined number of pulses are generated during each of the time intervals. An angular position of the light shielding system is determined and the phase of excitation of the motor is varied in response to the angular position. The pulses generated are used to drive the stepping motor in each of the plurality of time intervals.

Abstract: A pyroelectric detector is provided to measure the energy of pulsed light. To measure the power of continuous wave light (CW light), the pyroelectric detector is releasably attached to optical sampling apparatus which divides the CW light into pulsed light. Means are included to inform processor circuitry in the read-out electronics that the detector is attached to the optical chopper. The processor circuitry then calculates the power of the CW light given the energy of the pulsed light by the pyroelectric detector and the exposure time which is fixed by a crystal clock.

Abstract: PROBLEM TO BE SOLVED: To provide a photosensor having a configuration with the stability of an output value for calibration secured so that reliability and stability of calibration operation is improved. SOLUTION: The photosensor is provided with a reflection plate for calibration 14 for calibrating sensitivity and an optical path for calibration L3 for calibrating sensitivity inside the sensor, so that the positional relation of a light-emitting element 11, a light-receiving element 12 and the reflecting plate for calibration 14 is fixed. Thus, the stability of the output value for calibration can be secured, to improve the reliability of sensitivity calibration operation. An optical functional element 13 capable of switching the transmission/interception of light by the application of a voltage is installed in the optical path for calibration. The optical functional element is controlled into a light transmission state, when the calibration operation is performed and into a light interception state, when the calibration operation is not performed, so that the light cannot pass through the optical path for calibration L3, except when calibration operation is performed. Thus, extra operation work, such as, the separation of the influence of reflected light for calibration from the output value in normal detection becomes unnecessary. COPYRIGHT: (C)2009,JPO&INPIT
