    Abstract: Systems and methods are presented that use light sensors and computing devices to compute the depth of an object using shuttered light pulses (T). In one embodiment, depth is determined as follows: A light emitter emits a pulse of light that is directed toward an object. The pulse is reflected off the object and travels toward a beam splitter. The beam splitter splits the reflected pulse into multiple pulses, with each pulse directed to a shuttered sensor with a different shutter location (t). The shuttered sensors measure the integrated intensity of the light, and these values are used to determine the depth of the object. A method is presented which calibrates a system that has an arbitrary number of shutters and enables the system to determine the depth of an object, even in the presence of ambient illumination and scattered light.

    Abstract: A radiation detection panel has an integrated array of x-ray sensors, each of which includes a charge storage capacitor (14), a radiation sensitive layer (50) over the charge storage capacitor (14), and a control layer (52) over the radiation sensitive layer (50). The electrical conductivity of the control layer (52) can be changed reversibly in the field, after the panel is manufactured and without disassembly of the panel, to make the time constant of the layer t = (1/g)ke change between high and low values in the range of, e.g., 0.03 and 20 seconds, where g is the conductivity and k is the dielectric constant of the control layer, and e is the permittivity of free space. The conductivity, and thus the time constant of the control layer (52), are controllable via the application of electromagnetic energy, preferably infrared radiation. Preferably, the radiation sensitive layer (50) is a photoconductor and the control layer (52) is an organic photoconductor "OPC".

The control layer's electrical conductivity can be changed reversibly in the field, after the panel is manufactured and without disassembly of the panel, to make the time constant of the layer T=(1/y)Kε 0 change between high and low values in the range of, e.g., 0.03 and 20 seconds, wherein y is the conductivity and K is the dielectric constant of the control layer, and ε 0 is the permittivity of free space. The conductivity, and thus the time constant of the control layer, are controllable via the application of electromagnetic energy, preferably infrared radiation. Preferably, the radiation detection layer is a photoconductor and the control layer is an organic photoconductor (OPC).
