Arrangement for and method of imaging targets at plural focal planes |
摘要 |
An imaging arrangement for, and method of, imaging a target at one of a plurality of focal planes, includes a two-dimensional sensor having an array of pixels for converting incident light into electrical signals to be processed into an image of the target, and an optical assembly including a stationary optical element transmissive to the incident light en route to the sensor. The element is fixed relative to the sensor and has a plurality of optical portions respectively arranged in a plurality of patterns relative to a plurality of groups of the pixels. The assembly is operative for focusing the respective groups of the pixels in the respective patterns at respective focal planes spaced apart from one another away from the sensor.
