美国霍尼威尔光电中心研制了一种热释电探测器/硅CCD混合焦平面,它的红外探测和成象性能都很好,且成本低。这种LiTaO_3/CCD混合焦平面能够在室温下工作,光谱响应宽而平坦。霍尼威尔光电中心研制成了一种倒置、压接LiTaO_3/CCD模型,有10×32个象素、单元面积50×50mm~2,他们在热匹配条件非常接近混合结构的兰宝石衬底上做出了面积从50×50mm~2直到250×250mm~2的各种LiTaO_3试验列阵。50×50mm~2元件的响应率大于10~6V/W。他们将理论值和数据作了比较。在一个集成的LiTaO_3/CCD结构中,可以获得接近探测器噪声限的性能,这样,CCD的设计达到最佳,而且多路传输信号输出也适宜于用后焦平面电子学进行处理。
Honeywell Optoelectronics Center developed a pyroelectric detector / silicon CCD hybrid focal plane, which infrared detection and imaging performance are good, and low cost. The LiTaO 3 / CCD hybrid focal plane operates at room temperature with broad and flat spectral response. Honeywell Optoelectronics Center has developed an inverted, crimp LiTaO_3 / CCD model with 10 × 32 pixels with a cell area of 50 × 50 mm2. They are closely matched in hybrid configuration with sapphire substrates Made on the area of 50 × 50mm ~ 2 up to 250 × 250mm ~ 2 of various LiTaO_3 test array. Response rate of 50 × 50mm ~ 2 components is greater than 10 ~ 6V / W. They compared the theoretical value with the data. In an integrated LiTaO_3 / CCD structure, near-detector noise floor performance is achieved so that the CCD design is optimized and the multiplexed signal output is also suitable for processing with back focal plane electronics.
