簡(jiǎn)介:CCD航天光學(xué)遙感相機(jī)的成像與傳統(tǒng)的膠片成像有著很大的差異,膠片的顆粒度相對(duì)于光學(xué)系統(tǒng)彌散斑來(lái)說(shuō)它的大小可以忽略,而CCD探測(cè)器的像元尺寸一般來(lái)說(shuō)是光學(xué)系統(tǒng)彌散斑的幾倍,把以CCD探測(cè)器為接收器的光學(xué)成像系統(tǒng)看作是空間移不變系統(tǒng)會(huì)帶來(lái)一定的理論上的近似,因而在理論上不能準(zhǔn)確求得分辨力與像質(zhì)的關(guān)系,所以在實(shí)踐中又采用了平均意義的MTF。這里則采用模擬試驗(yàn)及計(jì)算機(jī)仿真的方法來(lái)研究在空間移變條件下的CCD遙感相機(jī)的影像分辨力和像質(zhì)問(wèn)題,這種研究不僅在理論上是一種補(bǔ)充,在工程實(shí)踐上也很有實(shí)際意義。鑒于CCD探測(cè)器成像是數(shù)字化成像,所以本文采用計(jì)算機(jī)仿真和CCD相機(jī)模擬成像試驗(yàn)及理論分析的方法對(duì)CCD探測(cè)器的目標(biāo)影像的分辨力與CCD像元分辨力的關(guān)系及像質(zhì)進(jìn)行了研究并獲得如下主要結(jié)論。1首先仿真了物像與CCD探測(cè)器相對(duì)靜止情況下的成像過(guò)程,仿真中的目標(biāo)采用鑒別率板的圖案即黑白相間的條帶。
