Abstract: A photon-counting type streak camera device measures by an integration operation the probability distribution of production timing of phenomenon light such as fluorescence light which a specimen produces upon reception of repeatedly generated pulse exciting light. A phenomenon streak camera system time-measures the phenomenon light, and a reference streak camera system time-measures reference light being synchronous with the exciting light. An arithmetic unit calculates the difference between outputs of the phenomenon and reference streak camera systems, so that the streak camera device can be prevented from being effected by a jitter or drift caused by a power change of a pulse light source.

Abstract: A microscope is modified to allow for precise imaging of samples using different filters at different focal planes under computer control. A filter accessory includes a filter disc having bandpass filters. The filter disc may be rotated to move a selected filter into the optical path between a light source and the microscope sample. Adjustment of the image plane of the microscope is controlled by the computer using feedback from a lens position sensor.

Abstract: An apparatus for measuring particles in a fluid comprises a laser source for producing a laser beam which is projected onto the fluid containing the particles. Laser light scattered by the particles is converted into an electrical signal consisting of pulses corresponding to the particles to be measured. The pulses are counted by first and second counters and processed in a processor to derive therefrom the diameter and/or concentration of the particles. The first and second counters are alternately operated for pulse counting and inhibited from pulse counting. Each counter transfers its count to the processor during the period that it is inhibited from counting.

Abstract: An accessory is provided to convert a conventional microscope to a microspectrofluorimeter. The accessory includes a filter disc having bandpass filters separated by opaque segments. The filter disc is rapidly and continuously rotated to move the filter sequentially into the optical path between a wideband light source and a microscope sample. Photon counting of radiation from the sample is synchronized to the position of the filters during rotation by means of synchronization marks on the filter disc. The same accessory may be positioned between the sample and a detector to detect emitted light of different frequencies.

Abstract: The various embodiments described herein include methods, devices, and systems for fabricating and operating transistors. In one aspect, a transistor includes: (1) a semiconducting component configured to operate in an on state at temperatures above a semiconducting threshold temperature; and (2) a superconducting component configured to operate in a superconducting state while: (a) a temperature of the superconducting component is below a superconducting threshold temperature; and (b) a first current supplied to the superconducting component is below a current threshold; where: (i) the semiconducting component is located adjacent to the superconducting component; and (ii) in response to a first input voltage, the semiconducting component is configured to generate an electromagnetic field sufficient to lower the current threshold such that the first current exceeds the lowered current threshold, thereby transitioning the superconducting component to a non-superconducting state.

Abstract: Superconducting nanowire single photon detectors have recently been developed for a wide range of applications, including imaging and communications. An improved detection system is disclosed, whereby the detectors are monolithically integrated on the same chip with Josephson junctions for control and data processing. This enables an enhanced data rate, thereby facilitating several new and improved applications. A preferred embodiment comprises integrated digital processing based on single-flux-quantum pulses. An integrated multilayer fabrication method for manufacturing these integrated detectors is also disclosed. Preferred examples of systems comprising such integrated nanowire photon detectors include a time-correlated single photon counter, a quantum random number generator, an integrated single-photon imaging array, a sensitive digital communication receiver, and quantum-key distribution for a quantum communication system.

Abstract: An optical energy detector and a method for detecting a broad range of optical energy are disclosed. The detector comprising a superconducting nanowire filament on a substrate, an electrical current pulse source, a laser pulse source, a first pickup probe, and a second pickup probe for measuring the voltage across the filament. The filament is maintained below a supercomputing critical temperature. The filament is biased with an electrical current pulses slight below the critical current of the filament which creates nonequilibrium state. The filament is excited by the laser pulses, and as a result, a voltage appears after a delay time. The voltage is measured for determining the amount of the optical energy. A reference curve of the voltage and the corresponding delay time can be used for calibrating any light source.
