Reading circuit for infrared detectors and method for inspecting same
A reading circuit for an infrared detector, includes: pixel driving circuits arranged in a matrix; vertical selection lines provided for respective rows of the pixel driving circuits; horizontal selection lines provided for respective columns of the pixel driving circuits; a vertical selection circuit configured to output a row selection signal to the vertical selection lines; and a horizontal selection circuit configured to output a column selection signal to the horizontal selection lines to read, to a reading line, a signal from pixel driving circuits for one row selected by the row selection signal, wherein each pixel driving circuit includes a driving circuit of the infrared detector, and a switching circuit configured to switch whether or not to input a test signal to the driving circuit, based on the row selection signal output to a corresponding vertical selection line and the column selection signal output to a corresponding horizontal selection line.
