A spinning flat plate calorimeter device is provided for receiving and measuring laser energy. The device includes a circular disk, a shaft, a structure and a motor. The circular disk has temperature-detection instrumentation for measuring temperature from the laser energy. The shaft is supported by distal and proximal bearings. The structure supports the disk, shaft and its bearings. The motor turns the shaft and the disk. Additionally, the disk further includes a flat plate, a yoke wheel and a plurality of spacers. The plate has an obverse face for receiving the laser energy and a reverse face with a spiral groove for attaching the instrumentation. The yoke wheel attaches to the shaft. The thermal isolator spacers mechanically attach the yoke wheel to the flat plate.

An actuator mechanism is provided for disposing a plurality of filters into and out of a camera line-of-sight. The mechanism includes a base, a pair of frames, an axial shaft, a plurality of filter housings and a plurality of pivotable drivers. The base includes an auxiliary platform. The frames flank the base, and the shaft is disposed between the frames. Each filter housing holds a corresponding optical filter and is disposable in a deployment position in the line-of-sight and a withdrawn position out of the line-of-sight. The drivers are disposed on the platform. Each driver corresponds to an associated housing and is rotatable along the shaft to swing at least one housing between deployment and withdrawn positions upon command.

Actuator for positioning optical filters

A calorimeter board is provided for power calibration of a laser emission. The board includes a flat metal plate, a sinuous groove and a resistance temperature detector wire. The flat metal plate has obverse and reverse surfaces separated by a thickness. The groove is cut into the reverse surface and penetrates to a depth being part of the thickness. The wire is disposed within the groove at the depth. The wire connects to an instrument that measures electrical resistance responsive to the laser emission on the obverse surface.

Laser calorimeter board

A directional slug calorimeter is provided to enable accurate non-isotropic heat flux measurement in a high-temperature environment. The slug calorimeter includes a tubular member; a plurality of slots formed along a portion of an axial length of the tubular member, insulation disposed within the tubular member and within the plurality of slots; and thermocouples disposed with a thermocouple junction. The plurality of slots divide the tubular member into discrete segments. The thermocouples are disposed in a central region of each of the discrete segments.
