Temperature Drift Modeling and Compensation for Gyroscope
2021Temperature, temperature change rate and temperature gradient are the main environmental factors that cause fog error. If the temperature effect of the optical fiber is considered, when the beam passes through the optical fiber length of L with the propagation constant \(\beta (z)\).

The Role Of Temperature And Temperature Drifts In Determining Performance Limits For SIRTF
SPIE Proceedings, 1986The temperature of the SIRTF optical system has two significant effects: it determines the contribution of the telescope thermal emission to the photon shot noise seen by the detectors, and it determines the magnitude of the telescope emission that constitutes the radiometric baseline against which astronomical measurements are made.

Generalized drift velocity of a cholesteric texture in a temperature gradient
Soft Matter, 2016We propose a general method to calculate the drift velocity of cholesteric textures subjected to a temperature gradient when the backflow effects are negligible. The textures may be Translationally Invariant Configurations (TICs) or localized structures such as cholesteric droplets or cholesteric fingers. For the TICs and for the droplets, the drift is

CMOS Voltage-to-Frequency Converter With Temperature Drift Compensation
IEEE Transactions on Instrumentation and Measurement, 2011This paper presents a new complementary metal-oxide-semiconductor (CMOS) differential voltage-to-frequency converter (VFC) suitable for sensor signal conditioning. Designed in a low-cost 0.18- μm CMOS process, the proposed VFC consumes less than 0.4 mW at a 1.8-V supply. For a differential input range of 0-1.2 V, output frequency varies from 0.1 to 1.1

Studies on the temperature dependent drift velocity for the HELIX Drift Chamber Tracker
Inquiry@Queen's Undergraduate Research Conference ProceedingsHELIX (High Energy Light Isotope eXperiment) is a ballon experiment designed to measure abundance of cosmic ray isotopes from hydrogen to neon, with a particular interest in abundances of beryllium isotopes. HELIX aim to provide essential data to study the cosmic ray propagation in our galaxy.

A long time low drift integrator with temperature control
Review of Scientific Instruments, 2016The output of an operational amplifier always contains signals that could not have been predicted, even with knowledge of the input and an accurately determined closed-loop transfer function. These signals lead to integrator zero-drift over time. A new type of integrator system with a long-term low-drift characteristic has therefore been designed.

Drift mobility of dopeda-Si:H at high temperatures
Physical Review B, 1987The traveling-wave drift mobility \ensuremath{\mu} was measured in two phosphorus-doped hydrogenated amorphous silicon (a-Si:H) samples which showed at ${T}_{K}$\ensuremath{\approxeq}380 K an upward kink in their conductivity curves and below ${T}_{K}$ a metastable excess conductivity after rapid quenching.

Temperature dependence of the c-axis drift mobility in 4H–SiC
Microelectronic Engineering, 2006The electrical characteristics of 4H-SiC Schottky diodes were performed in the temperature range 80-700 K, in order to determine the temperature dependence of the drift mobility. At room temperature, a value of 724 cm(2)/(V s) was found, which decreased to 48.6 cm(2)/ (V s) at 700 K. In the temperature range 200-700 K, a dependence of the mobility as T-

A helium high temperature drift chamber
2009We have built and operated a high temperature TPC which was integral to a polarized target originally designed for a triton detector at TRIUMF. The TPC is the key part for the improvement of the measurement accuracy in the study of the spin dependence of the reaction: μ⁻ + ³He → ³H + vμ.
