Abstract: Methods, devices, and systems that may help improve the dynamic range of a signal receiver. The method includes (i) causing a signal emitter to emit a signal during a first period of time; (ii) receiving, at the signal receiver, a reflected signal during a second period of time, where the received reflected signal corresponds to the emitted signal, and where the second period of time begins after a beginning of the first period of time; and (iii) increasing a signal gain that is applied to the received reflected signal during a third period of time, where the third period of time begins not earlier than a beginning of the second period of time.

Abstract: In some applications, it may be desirable to position multiple photodetectors at precise locations on a curved focal surface defined by an optical system. To achieve this positioning, the photodetectors may be mounted at desired locations on a flexible substrate that is in a flat configuration. The flexible substrate with mounted photodetectors can then be shaped to substantially conform to the shape of the curved focal surface. This shaping can be accomplished by clamping the flexible substrate between at least two clamping pieces. The curved flexible substrate clamped between the at least two clamping pieces can be positioned relative to the optical system such that the photodetectors are positioned at desired three-dimensional locations on the curved focal surface.
