Description

図6(a)に示すものはダイクロイックミラーを用いる方式である。これはダイクロイックミラー22c´により特定の波長の光を反射し、透過した残りの光について、さらに別のダイクロイックミラー22a´により別の特定の波長の光を反射して分光し、撮像素子23a、23b、23cを三つ並列にして読み出す方式である。ここでは、ダイクロイックミラー22a´が光学フィルタ22a、22bに相当し、ダイクロイックミラー22c´が光学フィルタ22cに相当する。撮影レンズ21から入射する光はダイクロイックミラー22c´により分光感度S3に従う光が反射され、残りの光は透過する。ダイクロイックミラー22c´により反射された光を反射鏡26により反射して撮像素子23cにより分光感度S3を得る。一方、ダイクロイックミラー22c´を透過した光は、ダイクロイックミラー22a´において、分光感度S1に従う光が反射され、残りの分光感度S2に従う光は透過する。ダイクロイックミラー22a´を透過した光を撮像素子23bにより撮像して分光感度S2を得る。ダイクロイックミラー22a´により反射された光を反射鏡29により反射して撮像素子23aにより分光感度S1を得る。ダイクロイックミラーに代えて同様な特性を有するダイクロイックプリズムを用いて三つに分光し、それぞれの光が透過する位置に撮像素子23a、23b、23cを接着することとしてもよい。 FIG. 6A shows a system using a dichroic mirror. This is because light of a specific wavelength is reflected by the dichroic mirror 22c ′, and the remaining light that has been transmitted is further reflected by another dichroic mirror 22a ′ to be spectrally separated, and the image pickup devices 23a, 23b. , 23c are read in parallel. Here, the dichroic mirror 22a ′ corresponds to the optical filters 22a and 22b, and the dichroic mirror 22c ′ corresponds to the optical filter 22c. Light incident from the photographic lens 21 is reflected by the dichroic mirror 22c ′ according to the spectral sensitivity S3, and the remaining light is transmitted. The light reflected by the dichroic mirror 22c ′ is reflected by the reflecting mirror 26, and the spectral sensitivity S3 is obtained by the imaging device 23c. On the other hand, the light transmitted through the dichroic mirror 22c ′ is reflected by the dichroic mirror 22a ′, and the light according to the spectral sensitivity S1 is transmitted, and the remaining light according to the spectral sensitivity S2 is transmitted . The light transmitted through the dichroic mirror 22a ′ is imaged by the image sensor 23b to obtain the spectral sensitivity S2. The light reflected by the dichroic mirror 22a ′ is reflected by the reflecting mirror 29, and the spectral sensitivity S1 is obtained by the imaging device 23a . Instead of the dichroic mirror, a dichroic prism having the same characteristics may be used to split the light into three, and the image sensors 23a, 23b, and 23c may be bonded to the positions where each light is transmitted.
