Imaging system having four image sensors

An imaging system comprising:

• an imaging lens;
• a first dichroic filter, a second dichroic filter, and a third dichroic filter;
• and
• a first image sensor, a second image sensor, a third image sensor, and a fourth image sensor;
• wherein the first dichroic filter reflects light having a first wavelength band and a second wavelength band toward a second dichroic filter, and transmits light having a third wavelength band and a fourth wavelength band toward the third dichroic filter,
• the second dichroic filter reflects light having the first wavelength band toward the first image sensor, and transmits light having the second wavelength band toward the second image sensor, and
• the third dichroic filter reflectes light having the third wavelength band toward the third image sensor, and transmits light having the fourth wavelength band toward the fourth image sensor;
• wherein the imaging lens forms a 2D image of the first wavelength band on the first image sensor, a 2D image of the second wavelength band on the second image sensor, a 2D image of the third wavelength band on the third image sensor, and a 2D image of the fourth wavelength band on the fourth image sensor;
• and
• wherein the first dichroic filter, the second dichroic filter, and the third dichroic filter are included in an integrated part.
