Abstract: A device of detecting a current from a sensor is disclosed. The device includes an integrating circuit including a network of capacitors for providing a gain setting and configured to convert the current to a voltage ramp over a length of integration time, the integrating circuit further including a reset switch configured to connect an input and an output of the network of capacitors; an ADC configured to digitize the voltage ramp into a plurality of voltage samples; and a set of modules including an analyzing module configured to analyze the plurality of voltage samples to determine a slope of the voltage ramp; an outputting module configured to determine a magnitude of the current based on the slope of the voltage ramp and the gain setting; and a reconfiguring module that is configured to reconfigure the network of capacitors and reset the voltage ramp via the reset switch.

Abstract: A system for measurement is provided. The system includes a first optical path configured to supply first light pulses with a first range of wavelengths; a second optical path configured to supply second light pulses with a second range of wavelengths shorter than the first range of wavelengths; an optical I/O unit configured to emit the first light pulses and the second light pulses to a target and acquire a light from the target to detect CARS light pluses from the target by a detector; and a first phase modulating unit configured to vary phase differences between the first light pulses and the second light pulses as the first light pulses and the second light pulses are emitted via the optical I/O unit.
