1. A patient monitoring device, comprising:
a transceiver for transmitting millimeter wave signals toward a target area and receiving reflected millimeter wave signals from the target area;
a replaceable lens attached to the transceiver, the replaceable lens being configured to collimate the millimeter wave signals transmitted from the transceiver, and the replaceable lens including a slidable handle for adjusting a focus of the millimeter wave signals between large and small dispersions; and
a signal analysis device having a processing device and at least one non-transitory computer readable data storage device storing instructions, that when executed by the processing device, cause the patient monitoring device to:
transmit the millimeter wave signals;
receive the reflected millimeter wave signals; and
determine a non-contact vital sign measurement based on the reflected millimeter wave signals.
