High-speed large-area pixels compatible with 200-Hz frame rates

Honeywell has developed a high-speed infrared emitter pixel and implemented the design on two 512 X 512 scene projector array designs. This pixel is a faster version of the original Gen-III Gossamer pixel implemented on previous 512 X 512 arrays. The new pixel has a 10% - 90% rise time under 4 milliseconds, enabling a dramatic increase in scene projection frame rates over currently available arrays. Full array frame rates of 200 Hz are not practical and subarrays can be driven up to 400 Hz. In spite of the increased speed, the array still maintains high brightness using the same CMOS electronics. This design and other array developments will be described.
