Method and Device for Imaging an Interior of a Turbid Medium

Abstract

The invention relates to a method and device (1) for imaging an interior of a turbid medium (55). A turbid medium (55) inside a measurement volume (15) is irradiated from a plurality of source positions (25a) with light from a light source (5), and light emanating from the measurement volume (15) is detected from a plurality of detection positions (25b). An image of the interior of the turbid medium (55) is reconstructed from the detected light. In both the method and the device (1), detector signals can be amplified for each source position-detection position pair by a multi-gain amplification unit comprising an amplifier circuit (60). The amplification factor is selected from a number of possible amplification factors based on detected signal strength in the prior art. According to the invention, however, the method and device are adapted such that the amplification factor is selected for at least one source position-detection position pair on the basis of an estimate of expected electrical signal strength.
