摘要:
According to one embodiment of the present invention, a system for viewing an area includes a dewar and an optical system positioned within the dewar. The dewar permits operation of the flux detector at cryogenic temperatures, in some embodiments. The optical system includes an infrared radiation system capable of focusing one or more light beams. The inclusion of the optical system within the cryogenic space of the dewar allows reduction of the overall system length and weight, if desired.

According to one embodiment, an optical device includes a variable aperture mechanism configured on a structure having a radiation detector that receives radiation through an aperture of the variable aperture mechanism. The aperture is selectively movable from a first position to a second position in which the aperture has a different size relative to the aperture in the first position. The structure is configured with one or more magnets that function with one or more magnetically permeable members configured on the variable aperture mechanism to hold the variable aperture mechanism in at least one position using a magnetic force between the magnets and magnetically permeable members.
摘要:
According to one embodiment, an optical device comprises a housing. A structure is disposed within the housing. The structure has an optical entrance whereby radiation may enter. An aperture is located between the optical entrance and a radiation detector. At least one brace is rigidly coupled to the structure and the housing.
摘要:
In certain embodiments, a system may include a sensor platform, a cold shield, and a support system. The sensor platform supports a sensor system. The cold shield allows first radiation to reach the sensor system and prevents second radiation from reaching the sensor system. The support system is coupled to the cold shield and the platform, and supports the cold shield and maintains a separation between the cold shield and the platform.
