Abstract: A bridge circuit arrangement, method of providing said bridge circuit arrangement, and uses thereof are described. The bridge circuit arrangement comprises a first photodevice configured on a first arm, a second photodevice configured on a second arm, a first resistor configured on a third, the first resistor being a variable resistor and a second resistor configured on a fourth arm of the bridge, the second resistor being a constant resistor. The first and second photodevice provide current flow in opposing directions. The first photodevice on the first arm includes a third resistor having an equivalent resistance to the first photodevice. The second photodevice on the second arm includes a fourth resistor having an equivalent resistance to the second photodevice. The bridge circuit arrangement is balanced by illuminating the first and second photodiode and adjusting the arrangement so the net current is zero.
