An optical sensor apparatus includes an optically transmissive structure (e.g., a prism) having two planar faces and a third planar face that connects the two planar faces, two or more light sources located outside the structure, and a photodetector array located outside the prism. The structure, light sources, and photodetector array are configured such that light from the light sources that is totally internally reflected at an optical interface between the prism and a sample outside the structure proximate one of the two planar faces is incident on a portion of the photodetector array that depends on a refractive index of the sample. The light sources are positioned with respect to the structure and photodetector array such that the totally internally reflected light from each light source corresponds to a different range of refractive index of the sample and maps to a corresponding portion of the photodetector array.

Optical sensor apparatus to detect light based on the refractive index of a sample

An optical sensor apparatus includes an optically transmissive structure having planar first, second, and third faces, two or more light sources located outside the structure adjacent the first face, and a photodetector array located outside the prism adjacent the first face. The structure, light sources, and photodetector array are configured such that light from the light sources that is totally internally reflected at an optical interface between the prism and a sample outside the structure proximate the second face is reflected at the third face and incident on a portion of the photodetector array that depends on a refractive index of the sample. The light sources are positioned with respect to the structure and photodetector array such that the totally internally reflected light from each light source corresponds to a different range of refractive index of the sample and maps to a corresponding portion of the photodetector array.

An arrangement, a method and a system to read information stored in a layer of ferroelectric media. The arrangement includes a layer including a ferroelectric media having one or more ferroelectric domains holding bit charges, a domain corresponding to information; a probe having a tip, wherein the media and the tip are adapted to move relative to one another such that the tip scans the ferroelectric domains of the media while applying a contact force to the domains to generate a direct piezoelectric effect within the domains; and circuitry coupled to the tip and adapted to generate a signal in response to an electrical coupling between the tip and the domains while scanning the tip in contact with the domains, the signal corresponding to a readout signal for ferroelectric bit charges stored in the media.

Arrangement and method to perform scanning readout of ferroelectric bit charges

According to embodiments of the present invention, a probe storage medium includes a conductive layer as an electrode and a metal, metalloid, and/or non-metal doped diamond-like carbon (DLC) layer disposed on the conductive layer. A probe array may be positioned close proximity with the layer of doped DLC. An individual probe in the probe array may have an atomic force microscope tip. The probe storage medium may be written to by applying a current, voltage, and/or power to the tip between a thresholds current, voltage, and/or power value and a limiting current, voltage, and/or power value. The current, voltage, and/or power cause the layer of DLC to change conductance. The probe storage medium may be read by applying a current, voltage, and/or power to the tip below a threshold current, voltage, and/or power value and sensing the conductance.
