    Abstract: The system is provided with a first branch (10, 12) and a second branch (14) which receive light from a sample and reference target respectively. A shutter (22) sequentially allows light from the two branches to pass to a mirror (20) having a slit (30), reflective portions (32) and transparent portions (34). Light from the first branch passes through portions (30) and (34) to a detecting branch (42, 46, 50-56) and some light is reflected through a lens (16) to eye piece (19). Similarly some light from the second branch passes through mirror (30) and (34) to eye piece (19) and some light is reflected to the detecting branch. Accordingly the measunngfield can be accurately identified by looking through the eye piece (19) whilst at the same time light is directed to the detecting branch for analysis.

    Abstract: PURPOSE: A pyroelectric infrared sensor system is provided to improve convenience of use by preventing a convenience unit connected to the pyroelectric infrared system from being shut off. CONSTITUTION: A pyroelectric infrared sensor system includes an induction unit for inducing a secondary detection by using a pyroelectric infrared sensor and a chopper(32). In order to obtain a relationship between the pyroelectric infrared sensor and the chopper(32), data detected by the pyroelectric infrared sensor are inputted into a microprocessor. When the chopper is moved, a signal value is detected by means of an infrared ray source. When the infrared ray source moves from a left to a right of the pyroelectric infrared sensor, signals having plus and minus values are detected from an X-axis.

    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.
