The presently disclosed subject matter provides methods, systems, and computer program products for optimizing a probe geometry for spectroscopic measurement in a turbid medium. According to one method, a probe geometry comprising one emitting entity for emitting electromagnetic radiation into a turbid medium and at least on collecting entity for collecting the electromagnetic radiation that has interacted with the turbid medium is selected. A simulation is performed with inputs of the probe geometry and a plurality of sets of optical property values associated with the turbid medium to generate output comprising optical parameter values measured by the probe geometry for each set of input optical property values. The measured optical parameter values are input to an inversion algorithm to produce corresponding optical properties as output. The produced optical properties are compared with optical properties known to correspond to the measured optical parameter values and a degree of matching between the produced optical properties and the known optical properties is determined. The simulation and inversion steps are repeated for a plurality of additional probe geometries. Each additional probe geometry differs from the previously tested probe geometry in at least one property. The property may be a quantity of collecting entities, a diameter of at least one emitting or collecting entity, a linear between the emitting and collecting entities, or combinations thereof. An optimization algorithm is applied at each iteration to select a probe geometry such that the resulting degree of matching will converge to an optimum value. An optimal geometry is selected based on the degree of matching determined for each geometry.
