Abstract

Various embodiments of the invention provide a device for detecting the range or the velocity or other state data for a target. According to various embodiments, the device includes a transmitter, a reflective surface, and a receiver. In various embodiments, the transmitter is configured to transmit laser pulses from the device towards a target thereby producing return laser pulses from the target. In particular embodiments, the reflective surface of the device is positioned to receive return laser pulses and is configured to reflect the return laser pulses from the target to a focal point. In various embodiments, the receiver is located at the focal point and is configured to detect the reflected laser pulses to generate a signal used to determine the target's range or velocity. The reflective surface can be used to replace a relatively heavy lens assembly normally mounted in the front of previous devices, thereby improving the balance of the device or reducing its weight.
