摘要:
The invention concerns a modifiable assembly of microscopic apertures comprising several plates (100, 110) that are opaque except on transparent parts (101, 114, 115), capable of moving relative to one another, to modify the size of resulting pinholes. The invention is applicable for microscopic apertures for confocal microscopy.

Confocal optical device for illuminating points on a sample 807 using illuminating beams FE and for detecting beams FD coming from the illuminated points and passing through a pinholes array 806. An exchangeable block 600 comprising a beamsplitter 602 and a redirection mirror 603 is used to superimpose the optical pathes of the illuminating beams FE and the beams to be detected FD.
摘要:
Confocal optical scanning device designed to allow visualization of an object to be observed (1107) and comprising: an optical system designed, on the one hand, to focus an illuminating beam (FX) coming from a light source on to at least one illuminating point (FXO) intended to illuminate a point of the object to be observed (1107) and, on the other hand, to focus a light beam (FE) coming from the illuminated point of the object (1107) on to a luminous point (FEO) in a first image plane (PI); at least one rotatably mounted mobile mirror (1104) on which are reflected, on the one hand, the illuminating beam (FX) to allow the scanning of the object to be observed (1107) along an observed plane and, on the other hand, the light beam (FE) to bring the luminous point (FEO) on to a fixed point on the first image plane; and a first spatial filtering system (1203) arranged in the first image plane and designed to filter the luminous point (FEO) to obtain a beam to be detected (FD). The optical system and the first spatial filtering system (1203) are designed to send back the beam to be detected (FD) on to said rotatably mounted mobile mirror (1104), the optical system is also designed to focus said beam to be detected (FD), on to a point to be detected (FDO) in a second image plane (P2) to obtain, in said second image plane, a movement of said point to be detected proportional to the movement of the illuminated point in the observed plane of the object.

The invention concerns a microscope for observing diffracting objects comprising a laser beam (2000) reflected by a first surface of mobile mirrors (2003) and (2007), passing through the condenser (2011), the sample (2040), the lens (2013), reflected by a second surface of mobile mirrors, passing through a filtering device (2019) and third-wave palates (2022) (2027) applying phase shifts only to the non-diffracted part of the wave, and detected by the cameras (2024) (2029) (2032). The invention is applicable in fast three-dimensional and two-dimensional microscopy, in biology and the study of materials.
摘要:
The invention concerns a microscope comprising an optical part for generating interference figures between a reference light wave and a light wave diffracted by the observed object, sensors for digitising these interference figures, actuators for operating the optical system, and a computer for receiving the digitised interference figures, controlling the actuators, and provided with a memory and computing means for computing the three dimensional images from the interference figures, based on a principle analogous to holography. The optical part enables the recording on a sensing surface (116) interference figures generated by a reference beam (Fr) and a beam (Fe) passing through a sample (109). The interference figures can differ from one another by the reference wave phase controlled by the piezoelectric actuator (120) or the spatial distribution of the illuminating beam controlled by the positioning device (106). This microscope can be used in biology or metrology.
摘要:
Receiver (5) for digital signals which comprises a differential decoding circuit deinterleaving and convolution decoding circuit for received digital signals. The differential decoding circuit restores each received symbol to the original phase it had on transmission. This permits the calculation of optimum metrics(M.sub.k.sup.a,M.sub.k.sup.b)which are used by convolution decoding circuit to provide optimum decoding of received symbols.
