Image sensor using a large-area high-aspect-ratio integral image sensor with plural light sensitive subareas
Among other things, an integral image sensor includes a sensor surface having a surface area at which light-sensitive pixels are arranged in rows and columns. The surface area includes two or more light-sensitive subareas each of the subareas having been configured to have been diced from a wafer along two orthogonal dimensions to form a discrete image sensor. The two or more light-sensitive subareas are arranged along one of the two orthogonal dimensions. The sensor surface of the integral image sensor is flat and continuous across the two or more subareas.
1. An apparatus comprising
a large-area high-aspect-ratio integral image sensor comprising two or more light-sensitive subareas in at least one row at a sensor surface,
a chamber configured to confine a sample at a supporting surface, the chamber having a chamber surface spaced from the supporting surface by a predetermined distance associated with characteristics of the sample, and
a processor and an application coupled to a memory, the application being configured to perform a count of elements in the sample.
2. The apparatus of claim 1 comprising a sensor drive circuit coupled to the integral image sensor.
3. The apparatus of claim 2 comprising a memory coupled to the sensor drive circuit.
