Infra-red (IR) imaging (in the LWIR and MWIR bands) is widely used for observation and surveillance applications. Most of IR optical materials are very sensitive to temperature changes. This sensitivity is reflected in a temperature dependent refractive index, that in turn it affects the focal lengt.....

Intraocular pressure (IOP), an important part of any eye exam, is measured with a special instrument called a tonometer. The most widely employed devices are the Goldmann and the air-puff tonometers. In both, the intraocular pressure is inferred from the force required to flatten (applanate) a const.....
