A device is disclosed for detecting time-resolved optical data, the device comprising a sensor comprising a number of detection elements configured to detect a light signal in a single photon regime, a timing circuit connected to said number of detection elements though a common line, and a control module connected to the sensor, the control module being configured to selectively enable the detection elements of the sensor according to a set of enabling patterns. The timing circuit is configured to measure a time of arrival of an output signal from the detection elements on the common line, the output signal being indicative of the detection of a photon of the light signal by any of the enabled detection elements.

Device and method for detecting time-resolved optical data

A Fourier-transform hyperspectral imaging system may include an optical imaging system configured to produce an image of an object, and an adjustable birefringent common-path interferometer module comprising a movable birefringent element and configured to produce interfering replicas of an input radiation which are delayed from each other by a phase delay adjustable by the moving birefringent element. The interferometer module may be configured to produce collinear replicas for entering optical rays parallel to said optical axis. The hyperspectral imaging system further comprises a two-dimensional light detector configured to receive the replicas and provide digital images of the object depending on said adjustable phase delay. The system also includes an analysis device configured to perform a Fourier Transform of the digital images to obtain a hyperspectral representation of the object.
