Absolute timing of the Crab Pulsar at optical wavelengths with STJs
Context. We have observed the Crab Pulsar in the optical with S-Cam, an instrument based on Superconducting Tunneling Junctions (STJs) with μs time resolution. Aims. Our aim was to study the delay between the radio and optical pulse. Methods. The Crab Pulsar was observed three times over a time span of almost 7 years, on two different locations, using three different versions of the instrument,...
متن کاملMultichannel photon counting instrument for spatially resolved near infrared spectroscopy
We have developed a multichannel photon counting instrument for near infrared spatially resolved spectroscopy. The instrument uses two laser diodes at 780 and 830 nm. The two wavelengths are time multiplexed at a rate of 5 MHz for virtually simultaneous measurements at the two wavelengths. The photon pulses are then multiplexed with an optical switch so that the incident optical signals are dir...
متن کاملFrequency domain near-infrared multiwavelength imager design using high-speed, direct analog-to-digital conversion.
Frequency domain near-infrared spectroscopy (FD-NIRS) has proven to be a reliable method for quantification of tissue absolute optical properties. We present a full-sampling direct analog-to-digital conversion FD-NIR imager. While we developed this instrument with a focus on high-speed optical breast tomographic imaging, the proposed design is suitable for a wide-range of biophotonic applicatio...
متن کاملReference optical phantoms for diffuse optical spectroscopy. Part 1--Error analysis of a time resolved transmittance characterization method.
Development, production quality control and calibration of optical tissue-mimicking phantoms require a convenient and robust characterization method with known absolute accuracy. We present a solid phantom characterization technique based on time resolved transmittance measurement of light through a relatively small phantom sample. The small size of the sample enables characterization of every ...
متن کاملAbsolute Flux Calibrated Spectrum of Vega
An absolute flux calibrated reference spectrum of Vega, the primary calibration standard in the optical, is presented. The spectrum covers the entire 0.12 to 2.6 microns wavelength. The ultraviolet spectrum is based on IUE measurements. The optical and near-infrared up to 1.05 microns consists of Hayes (1985) average spectrum. A model spectrum normalized to Hayes (1985) Johnson V flux covers th...
