Subject: Re: [EE] Dental xray sensors Energy spectrum is a tougher requirement. You need a scintillator material = which has a high energy resolution (they tend to blur different input photo= ns into closer-wavelength visible light photons unless they are a special k= ind) You also need a detector which can measure the brightness of each phot= on, even when multiple photos hit the same pixel with very little separatio= n.
