Abstract
The present technology relates to an optical pulse detection device, an optical pulse detection method, a radiation counter device, and a biological testing device which are capable of performing radiation counting in a more accurate manner. The optical pulse detection device includes a pixel array unit in which a plurality of pixels are arranged in a two-dimensional lattice shape, an AD converter that converts output signals of each of the pixels in the pixel array unit into digital values with gradation greater than 1 bit, and an output control circuit that performs error determination processing of comparing the digital value with a predetermined threshold value, and discarding a digital value, which is greater than the threshold value, among the digital values as an error. For example, the present technology is applicable to a radiation counter device, and the like.
