Disclosed are various embodiments for integrated diffuse correlation spectroscopy. A first control signal can be sent to a switch to cause an integrator to integrate a current from a photodiode. An integrated current can be received from the integrator, and a data signal can be sent to a computing device based at least in part on the integrated current. A second control signal can be sent to a switch to cause the integrator to cease integrating the current from the photodiode.

Systems or methods for losslessly compressing data received from sensors, such as photon counters, are disclosed. An integer representation of a sensor reading is received from a sensor. The integer representation is combined with additional integer representations from each of a plurality of additional sensors into a single integer value. The single integer value is then stored as an element of an integer array that represents a predefined sample interval.

A partitioned aperture wavefront imaging system includes an imaging system comprising a partitioned aperture lens array positioned at the aperture plane or Fourier plane between the entrance plane and camera plane of an imaging system. The partitioned aperture lens array can include 2 or more off-axis lenses symmetrically distributed about an optical axis, and adapted to produce simultaneously at the camera plane at least two images of an object, or intermediate image of an object, presented at the entrance plane. Preferably, the partitioned aperture lens array includes from 3 to 5 off-axis lenses and produces 3 to 5 images at the camera plane from which phase and amplitude information about the light field can be determined. The partitioned aperture wavefront imaging system provides enough information about the light field presented at the entrance plane to enable reconstruction of the light field at other planes relative to the entrance plane.
