The optical measurement system comprising a diagnostic, measurement and repair equipment arranged on the object for example a vehicle via a rigid linking structure. The system comprises a measuring head and one or more targets comprising one or more set of photodiodes. The measuring head is mounted under or on the vehicle. The system is configured to measure parameters representative of the vehicle. The device further comprises a computing device in communication with the equipment, comprising set of instructions to determine a position of the target regarding to a reference point. The location of the point is then compared to an original location of the point to determine the damage in the vehicle. ## Claims ### Claim 1 An optical system for evaluating a frame of a vehicle, comprising: a diagnostic, measurement and repair equipment arranged on the vehicle comprising, one or more targets secured at a desired location of the vehicle having an electronic circuitry including at least one set of photodiodes, and a measuring head detachably mounted at a desired location via a linking structure comprising, a laser configured to emit laser beam towards the at least one set of photodiode, and at least two encoders configured to generate parameters representative of the vehicle; a database comprising memory unit for storing one or more vehicle information necessary to diagnose the vehicle; and a computing device in communication with the database and the diagnostic test equipment via a wireless network is configured to: receive data representative of one or more parameters of the vehicle, determine a position of the target to a reference point based on the parameters of the vehicle and position of the point of the vehicle, and compare a position of the point of the vehicle with the vehicle information in the database to evaluate the state of the vehicle. ### Claim 2 (depends on 1) The system of claim 1, wherein the parameters representative of the vehicle comprises, (a) distance between the point of emission of the laser and the at least one set of photodiode, (b) angle between the direction of laser and horizontal axis, and (c) orientation of the laser regarding the vertical axis. ### Claim 3 (depends on 1) The system of claim 1, wherein the target is secured to the specific location of the vehicle via a magnetic or mechanical attachment. ### Claim 4 (depends on 1) The system of claim 1, wherein the diagnostic, measurement and repair equipment and the target are configured to be rigidly arranged on the vehicle without variation of the distance between the target, and structure of the vehicle to provide accurate parameters. ### Claim 5 (depends on 1) The system of claim 1, wherein the at least two encoders is a rotary encoder. ### Claim 6 (depends on 1) The system of claim 1, wherein the laser is a rotating laser. ### Claim 7 (depends on 1) The system of claim 1, wherein the measuring head and the target are mounted under the vehicle. ### Claim 8 (depends on 1) The system of claim 1, wherein the measuring head is configured to rotate in two directions to hit the target. ### Claim 9 (depends on 1) The system of claim 1, wherein the wireless network is at least anyone or combination of Wi-Fi network, WiMax network, or wireless local area network. ### Claim 10 (depends on 1) The system of claim 1, wherein the computing device is at least one of tablet computers, personnel computers, personnel digital assistants, smart phones, smart televisions, palm tops, phablets and laptops. ### Claim 11 (depends on 1) The system of claim 1, wherein the memory unit is at least one of a volatile memory, non-volatile memory, read only memory (ROM), random access memory (RAM), and a flash memory. ### Claim 12 A method for operating an optical system for evaluating a frame of a vehicle, the method comprising the steps of: arranging a diagnostic, measurement and repair equipment on the vehicle comprising the steps of securing one or more target at a specific location of the vehicle having an electronic circuitry including at least one set of photodiodes, and attaching a measuring head at a desired location via a linking structure comprising, a laser configured to emit laser beam towards the photo diodes, and at least two encoders configured to generate parameters representative of the vehicle; providing a database comprising memory unit for storing one or more vehicle information necessary to diagnose the vehicle; receiving data representative of one or more parameters of the vehicle from the diagnostic test equipment via a wireless network, at a computing device in communication with the database; determining, via the computing device, a position of the target regarding to a reference point based on the parameters of the vehicle and position of the point of the vehicle, and comparing, via the computing device, a position of the point of the vehicle with the vehicle information in the database to evaluate the state of the vehicle. ### Claim 13 (depends on 12) The method of claim 12, wherein parameters representative of the vehicle comprises, (d) distance between the point of emission of the laser and the photodiode, (e) angle between the direction of laser and horizontal axis, and (f) orientation of the laser regarding the vertical axis. ### Claim 14 (depends on 12) The method of claim 12, wherein the diagnostic, measurement and repair system and the target are configured to be rigidly arranged on the vehicle without variation of the distance between the target, and structure of the vehicle to provide accurate parameters. ### Claim 15 (depends on 12) The method of claim 12, wherein the measuring head and target are mounted and fixed under the vehicle. ### Claim 16 (depends on 12) The method of claim 12, wherein the measuring head is configured to rotate in two directions to hit the target.
