Timepix3: Compensation of Thermal Distortion of Energy Measurement
Sensors, 2023 The Timepix3 is a hybrid pixellated radiation detector consisting of a 256 px × 256 px radiation-sensitive matrix. Research has shown that it is susceptible to energy spectrum distortion due to temperature variations. This can lead to a relative measurement error of up to 35% in the tested temperature range of 10 °C to 70 °C.

Non-Uniform Offsetting and its Applications in Laser Path Planning of Sterolithography Machine [PDF]
, 2007 Laser path planning is an important step in solid freeform fabrication processes such as Stereolithography (SLA). An important consideration in the laser path planning is to compensate the shape of laser beam. Currently the compensation is divided into

Thermal effects and their compensation in Advanced Virgo
Journal of Physics: Conference Series, 2012 Thermal effects in the test masses of the gravitational waves interferometric detectors may result in a strong limitation to their operation and sensitivity. Already in initial LIGO and Virgo, these effects have been observed and required the installation of dedicated compensation systems.

Multipass amplifiers with self-compensation of the thermal lens [PDF]
Applied Optics, 2018 We present a novel architecture for a multi-pass amplifier based on a succession of optical Fourier transforms and short propagations that shows a superior stability for variations of the thermal lens compared to state-of-the-art 4f-based amplifiers. We found that the proposed multi-pass amplifier is robust to variations of the active medium dioptric ...

Use of a compensation parameter in the thermal decomposition of copolymers [PDF]
Thermochimica Acta, 1986 During the past 25 years, thermal techniques have been widely used to study the kinetics of solid state decomposition reactions. In principle, one should find prodigious data on homopolymers, to facilitate the interpretation of the thermal decomposition behaviour of copolymers.
