Abstract: Example embodiments relate to an integrated lens-free imaging device. One embodiment includes a lens-free imaging device for imaging a sample. The lens-free imaging device includes a radiation guiding structure that includes a first surface parallel with a second surface. The lens-free imaging device also includes an imaging region. The radiation guiding structure is adapted for receiving an incoming radiation wave, thereby obtaining a confined radiation wave. At least one perturbation is present in the radiation guiding structure for generating, from the confined radiation wave, a first radiation wave and a second radiation wave. The radiation guiding structure is configured to direct the first radiation wave out of the radiation guiding structure toward the first surface to a sample measurement region. The radiation guiding structure is further configured to direct the second radiation wave toward the second surface to the imaging region.

Abstract: The invention relates to a multi-channel spectrometer device (10) for detecting/quantifying a predetermined analyte (5) in a medium (6). The device (10) comprises an input (11) for receiving radiation (7), a first plurality of optical modulators (12) adapted for transforming the radiation (7) in accordance with a first transfer function, and a second plurality of optical modulators (13) adapted for transforming the radiation (7) in accordance with a second transfer function. The spectrometer device also comprises a detector (15) for generating output signals (4) indicative for the intensity of each transformed radiation signal. The ratio of the number of optical modulators in the first plurality and the number of optical modulators in the second plurality is determined by the ratio of a reference spectrum of the predetermined analyte transformed by the first transfer function and the reference spectrum transformed by the second transfer function.

Abstract: Embodiments relate to a sensor structure for an acoustical pressure sensor and an opto-mechanical sensor and system that may be used for detecting acoustical pressure waves. Embodiments of a sensor structure for an acoustical pressure sensor include an optical waveguide closed-loop resonator and a plurality of sensor elements. The individual sensor elements of the plurality of sensor elements are configured to be affected by an acoustical pressure wave such that a physical property of the individual sensor element is changed. The optical waveguide closed-loop resonator is arranged at the plurality of sensor elements and associated with each of the individual sensor elements such that a resonance frequency of the optical waveguide closed-loop resonator is shifted due to the affected physical properties of all individual sensor elements. The sensor structure provides a high sensitivity from each sensor element, which is advantageous in e.g. ultrasonic imaging, such as photo-acoustic imaging where the signals typically are low.

Abstract: A system and for distributing data for 3D light field projection and a method thereof. The system comprises input terminals and output terminals that are connectable to pixel elements of a display. Data paths are established between input terminals and output terminals, and are controlled by data switches. The system also comprises a control plane adapted for applying control variables to the data switches. Control switches of the control plane select the control variables which are applied to the data switches. Sequences of control variables and enable variables propagate along at least one first delay line and along at least one second delay line respectively. Delay units of the at least one first delay line and of the at least one second delay line have a synchronous relationship. During system run-time patterns contained in the stream of input data are detected for determining the sequences of control variables.
