摘要： Techniques are disclosed for systems and methods to provide thermal despace compensation for optics assemblies, such as devices including one or more lenses and/or optical devices. A thermal despace compensation system may include one or more interfaces substantially situated between optical devices that expand and contract with changing temperature according to their coefficients of thermal expansion (CTEs). Each interface may be implemented with one or more shapes and/or interfaces adapted to provide a compensation despace to compensate for thermal expansion and contraction and/or reduce optical defects caused by changes in temperature of the various optical devices.

摘要： A piezoelectric device includes an elastic member, an electrical-mechanical energy conversion element fixed to the elastic member, configured to cause the elastic member to generate vibration, and a supporting member that supports the elastic member. The electrical-mechanical energy conversion element is formed of a piezoelectric material in which, in a usage temperature range of the piezoelectric device, a piezoelectric constant decreases along with temperature rise. A supporting member that supports the elastic member is formed of a material in which, in the usage temperature range of the piezoelectric device, Q value increases along with temperature rise.
