1. A multi-channel densitometer for measuring optical density of sample areas, said densitometer comprising:

  • from 3 to 8 sensors distributed on a probe and facing said sample areas, such that each said sensor receives light impinging first upon the sample area opposite said sensor, and thence from said sample area to a light detector of said sensor, and has an output characteristic of the light intensity incident on said light detector, and a controller circuit electrically connected to each said sensor, said controller circuit providing power to said sensors, and receiving said outputs from said sensors;

    whereby said controller circuit collects signals characteristic of the optical density of said sample areas at positions opposite the respective sensors.
