The invention relates to an apparatus for probing a sample comprising a light source for emitting an illuminating light beam, a birefringent element for splitting the illuminating light beam into two sheared beams, a reflective element for reflecting the two sheared beams, wherein the apparatus is configured such that the reflected beams propagate through the birefringent element for recombining the reflected beams, and a detector for detecting the recombined beam, wherein the sample is arrangeable in the optical path of the sheared beams or at the backside of a reflective surface in the optical path of the sheared beams, the reflective surface exhibiting a surface plasmon resonance or a localized surface plasmon resonance.

Apparatus for exploring an optical property of a sample

An image cytometer for capturing and analyzing the image of a sample in the momentum domain. The cytometer is provided with a light source for illuminating a sample with a light beam, an optical transforming system positioned behind the sample in the beam propagation direction for generating the Fourier transform in the space plane, a light sensor array and a spatially selective filter positioned with respect to the optical system such that the Fourier transform is imaged onto the light sensor array.

Image cytometer for characterization and quantification of particulate samples

Apparatus for measuring light scattering of a sample comprising a light beam source, means for collimating the beam and making it impinge on the sample in a perpendicular direction, at least one light sensor, and at least one spatial filter between the sample and the optical sensor, provided with two apertures, means for measuring the total power reaching the sensor and means for measuring the power of beams with a low k vector after the beam traverses the filter. The invention provides thus a simplified, portable and compact device for measuring different parameters like haze, turbidity, etc. can be built, for any sample and without the need of changing detectors.
