A sensor system, device, and methods for determining the concentration of an analyte in a sample is described. The perspective is reduced in an image by receiving a first image of a first field of view and receiving a second image of a second field of view. One transducer is coupled to one of the rigid mount boosters. The laser driver also has a temperature compensation mechanism for monitoring the temperature of the driver IC and selectively adjusting the dc and ac parameters of the VCSEL drive waveform to compensate for the changes in temperature.
