Abstract: Radiation sensor including a detection assembly and a chopper assembly, which are mechanically coupled to delimit a main cavity; and wherein the chopper assembly includes: a suspended movable structure, which extends in the main cavity; and an actuation structure, which is electrically controllable to cause a change of position of the suspended movable structure. The detection unit includes a detection structure, which faces the main cavity and includes a number of detection devices. The suspended movable structure includes a first shield of conductive material, which shields the detection devices from the radiation, the shielding of the detection devices being a function of the position of the suspended movable structure.

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 detector for use in optical measuring instruments such as a double-beam spectrophotometer, comprising a photoelectric element having a photosensitive surface and a beam mixer disposed adjacent the photosensitive surface for causing each of two alternate light beams to be projected evenly and uniformly onto the photosensitive surface of the photoelectric element thereby to eliminate errors which would otherwise be caused in the result of measurement due to local difference in sensitivity of the photosensitive surface of the photoelectric element. The beam mixer comprises a symmetrical pair of light diffusing plates so arranged as to form a roof-shaped configuration and a tublar body having one end opening closed by the pair of light diffusing plates and the opposite end opening closed by the photosensitive surface of the photoelectric element.

Abstract: There is disclosed a light modulating structure including an open-ended housing within which an electromagnetically driven tuning fork structure is supported. A source of light is located between the tines of the tuning fork. Apertured shutter members are secured to the ends of said tines intermediate the light source and the open end of said housing, relative movement of the shutter members causing variations in light intensity emitted by the light modulating structure. The tuning fork is of composite construction and is manufactured by a method which involves shaping at least two tuning fork tines to a desired thickness in a single machining operation before the two tines are separated and joined together symmetrically to form a composite tuning fork.

Abstract: A synchronizing light chopper which is rotatable and has a mechanical member in the form of a cylinder with a multiplicity of slots cut therethrough. One of the slots is wider than the others and permits a longer light pulse therein which is used to reset the flip-flop to its initial zero state. Thus, synchronization is ensured in spite of spurious, unwanted trigger pulses.
