摘要： Laser apparatus containing an electrically operated laser (laser diode) is temperature stabilized so that it is able to generate a beam of laser light of sufficient intensity to be suitable for use in a laser printer without entering a failure mode due to overheating. The laser diode is integrated into a hybrid thick film integrated circuit wherein the laser diode is bonded to one side of the hybrid's substrate of thermally conductive and electrically insulating material of the hybrid. The hybrid has conductors thereon which are connected to the leads from the laser diode. A circuit containing temperature sensitive material (elements formed of positive or negative temperature co-efficient resistive material) is distributed in spaced areas on the opposite side of the hybrid's substrate from the laser diode. The distributed thermistor circuit and its close thermal coupling to the cooler and the diode laser reduce thermal mass (capacitance), which must be heated or cooled, to maintain athermal conditions. A control circuit responsive to the thermistor resistance which includes a proportional gain stage which follows rapid changes in thermistor resistance and an integral stage which prevents slow changes in thermistor resistance from rendering the temperature unstable, provides current in the proper direction through the cooler so as to maintain and stabilize the temperature of the laser.

摘要： Embodiments relate to detector imaging arrays with scintillators (e.g., scintillating phosphor screens) mounted to imaging arrays or radiographic detectors using the same. For example, the detector imaging arrays can include a scintillator, an imaging array comprising imaging pixels, where each imaging pixel comprises at least one readout element and one photosensor; and a first dielectric layer formed between the scintillator and the imaging layer, wherein the dielectric constant of the insulating layer is very low. Embodiments according to the application can include a second dielectric layer formed over at least a portion of the non-photosensitive regions of the array and/or a first dielectric layer, each with a dielectric constant.
