Abstract: The invention relates to a method and a device for obtaining a low-noise optical signal.According to the method, a luminous beam is injected through two apertures and after detection respectively a basic optical signal (21) and a corrective optical signal (22) are generated. Both optical signals obtained (21, 22) are subtracted, so that a resulting optical signal is generated, forming the low-noise optical signal. The apertures are preferably two slits of a spectroscope, the optical signals being expressible relative to the wavelength.

Abstract: A device for measuring the intensity of incoming light is disclosed. This device includes a rotatable light blocking unit which interrupts incident signal light at short regular intervals. The device also includes a light source which emits certain light different from the signal light while the signal light is interrupted by the block unit, and a measurement unit for measuring intensity values of the signal light and the certain light. A correction unit is provided for correcting the measured signal light intensity based on the certain light intensity. A calculator unit calculates a correction value through comparison of the intensity of the certain light to a reference value. The correction unit uses this correction value to correct the signal light intensity.

Abstract: A device for characterizing the formation of a sheet material is described. The device comprises a basis weight sensor for measuring the basis weight of the sheet material as the material moves through the sensor and signal processing circuitry which receives a signal from the basis weight sensor indicative of the measured basis weight. The basis weight sensor includes a light source for directing a beam of light at the moving sheet and a light detector which detects the beam after it passes through the sheet. This detector produces a signal indicative of the intensity of the detected beam and transmits the signal to the signal processing circuitry. To calibrate the signal processing circuitry, a rotatable opaque wheel having a plurality of slots is positioned in the path of the light beam. The rotating wheel alternately blocks the light beam and allows the beam to pass through the slots to the detector. By rotating the wheel at a predetermined speed, the signal produced by the light detector is modulated at a predetermined frequency dependent upon the rotational speed of the wheel and the number of slots in the wheel. After calibration, an electromagnet rotates and holds the wheel in a position wherein the light beam passes, unobstructed by the wheel, through one of the slots.

Abstract: A two beam alternating light colorimeter is disclosed wherein a light beam passing through a lens system having a shutter is periodically deflected by a pivoting mirror. In a first non-deflecting position of the pivotable mirror a first measuring beam is created which passes through a first measuring cell and is guided to a common photo cell. In a second deflecting position of the mirror a second measuring beam is created which is guided through a second measuring cell to the same photo cell. Signals from the photo cell are connected through a controlled switching element to an analog memory. A computing circuit is provided which connects to an output of the analog memory and also to the photo cell. The switching element connects the first measuring signal to the analog memory when the mirror is in a non-deflecting position and opens when the mirror is in a deflecting position. The computing circuit compares the signals corresponding to the first and second measuring beams.

Abstract: Process for the photo-optical measurement of the absorption behavior of solid, liquid and gaseous media. A measurement light beam from an optical radiation source is made intermittent by a rotating chopper comprising a rotatable metal wheel. The chopper frequency is maintained constant by regulation of the speed of the metal wheel by two alternating-current magnets inducing eddy currents to slow or speed up the wheel. The actual speed of the wheel is detected and compared with a reference speed and the magnitude of the excitation currents is adjusted on the basis of the rotatory speed difference to effect the regulation of the speed of the chopper.

Abstract: Operation between a beam switch which directs light to a photoelectric detector and a gating means for directing signals from the photoelectric detector to separate storage channels is synchronized by generating a marker pulse within a sequence of clock pulses which correspond to the positions of the beam switch. Signals from the separate storage channels are directed to an analyzing means in a predetermined sequence by the gating means and sequencing within the analyzing means is also accomplished thereby. Furthermore, comparative analysis between signals corresponding with two positions of the beam switch is provided at the input to and/or the output from the separate storage channels.

Abstract: A spectral sensor operating with a radiation sensitive detector employs a pulsed signal. A chopper is interposed in the radiation path comprising a needle of a moving needle meter whose needle is restrained at its tip. An alternating current applied to its coil causes the needle to vibrate, alternately exposing and blocking the detector. The sensor is low cost, and sensitive enough to respond to a temperature differential between a normal area and an inflamed area of a human body. Operating ranges can be varied by adjustment of electrical circuits or by interchangeable filters.
