A method and apparatus for rapidly erasing and rebiasing a thermoptic thin film. A thermal insulating material (16) is disposed adjacent a thermoptic thin film (10). A layer of resistive material (14) is disposed between the insulating material and the thermoptic thin film and is connected to a current generator (18) which supplies a current to the layer dissipating heat into the thermoptic thin film and insulating layer. A thermal body (22), having high thermal conductivity and interfacing with the insulating layer the opposite boundary from the thermoptic thin film, contains a conduit through which a refrigerated liquid is flowed to establish a thermal gradient from the thermoptic thin film to the fluid. Sufficient current is supplied to the resistive layer to maintain the temperature of the thermoptic thin film at the bias temperature. A control circuit is provided for intermittently interrupting the current flow, causing heat to dissipate from the thermoptic thin film and the temperature to drop to a point below the hysteresis loop, whereby images written in the thermoptic thin film are erased.

Alkali electric discharges have been considered previously for night-vision illuminator applications due to copious near-infrared emissions. However, high-pressure alkali short arc lamps exhibited low brightness, particularly at the cathode tip. The cause of this phenomenon is now recognized and a lamp invented which exhibits a small volume arc of high brightness. This lamp has better beam collimation and focussing characteristics than previously tested alkali lamps.

Devices and methods are taught by this invention of populating excited energy levels with fundamental particles. When these populated excited energy levels are further pumped, a population inversion used in quantum electronic applications can result. Each of the various methods involve pumping on an excited energy level of an elemental physical system to cause, by the absorption of energy, the transition of fundamental particles from the excited energy level to a higher energy level. Part of the energy is used for transition of fundamental particles residing in neighboring elemental physical systems from the lowest energy to the excited energy level.

A new system for millimeter wave electronic imaging is described. This system utilizes a spatial light modulator in the focal plane of the collection optics. Each pixel of the modulator is driven by a specific high duty cycle modulation function provided by a modulation function generation circuit. Thus the throughput radiation at each pixel is uniquely labeled(encoded). A post modulation detector sums the signal from all the pixels. Subsequent to detection, the appropriate transform of the sum signal yields specific pixel throughput radiation intensity levels. Several configurations are described including one transmittance configuration and two reflectance configurations. Three specific millimeter wave transmittance embodiments and one reflectance embodiment are also described.
