A light detection and ranging system includes a transmitter transmitting a transmitted light pulse timing sequence, with pseudo-random timing and including a plurality of light pulses, toward a target. A baseplate disposed adjacent to the speaker outlet can combine with the housing of the phone to form a flaring, right-angled horn having an inlet coupled to the outlet of the speaker and an outlet terminating at a periphery of the housing. A first isolator diaphragm is located proximate the first process fluid inlet and is operably coupled to the first sensor inlet through a first fill fluid volume. The overall goal is to allow an operator to select which imagery from multiple WFOV sensors to display in order to prescreen regions of interest that require further investigation using sensors with more magnification. According to the present invention, the distribution chute comprises a circumferentially closed funnel portion which tapers in the direction of flow and is arranged downstream of the impact section and with its outlet at the downstream end of said trough-shaped main part.
