Resolution

The highest spatial resolution achievable with liquid crystal thermography is limited by the type of liquid crystal formulation and resolving capacity of the optical system (namely, camera and lenses). A camera with a pixel array of 1024 × 1024 sensors viewing a 50 × 50 mm² surface would be able to record scattered light intensities from a single pixel whose size is approximately 50 × 50 µm² .
The encapsulated liquid crystal itself would be smaller than this size and presents the lower limit of area where a unique temperature can be assigned. These dimensions are often acceptable in laboratory scale measurements. The accuracy of temperature measurement and the resolution obtainable in an experiment with LCs is directly related to the accuracy and consistency of their color-temperature response. Inconsistency in lighting and viewing arrangements can contribute significantly to measurement errors in liquid crystal thermography.
